(a) Computer Monitor: An electronic device, typically with a diagonal screen size greater than 12 inches and a pixel density greater than 5 000 pixels per square inch (pixels/in2), that displays a computer’s user interface and open programs, allowing the user to interact with the computer, typically using a keyboard and mouse.
Enhanced-Performance Display: A computer monitor that has all of the following features and functionalities:
(i) A contrast ratio of at least 60:1 measured at a horizontal viewing angle of at least 85°, with or without a screen cover glass;
(ii) A native resolution greater than or equal to 2,3 megapixels (MP); and,
(iii) A colour gamut size of at least sRGB as defined by IEC 619662-1. Shifts in colour space are allowable as long as 99 % or more of defined sRGB colours are supported.
(b) Digital Picture Frame: An electronic device, typically with a diagonal screen size less than 12 inches, whose primary function is to display digital images. It may also feature a programmable timer, occupancy sensor, audio, video, or bluetooth or wireless connectivity.
(c) Signage Display: An electronic device typically with a diagonal screen size greater than 12 inches and a pixel density less than or equal to 5 000 pixels/in2. It is typically marketed as commercial signage for use in areas where it is intended to be viewed by multiple people in non-desk based environments, such as retail or department stores, restaurants, museums, hotels, outdoor venues, airports, conference rooms or classrooms.
1.2. External Power Supply (EPS): Also referred to as an external power adapter. A component contained in a separate physical enclosure external to a display, designed to convert line voltage ac input from the mains to lesser dc voltage(s) in order to provide power to the display. An EPS connects to the display via a removable or hard-wired male/female electrical connection, cable, cord or other wiring.
1.3. Operational Modes:
(a) On Mode: The power mode in which the product has been activated, and is providing one or more of its principal functions. The common terms, ‘active,’‘in-use,’ and ‘normal operation’ also describe this mode. The power in this mode is typically greater than the power in Sleep Mode and Off Mode.
(b) Sleep Mode: The power mode the product enters after receiving a signal from a connected device or an internal stimulus. The product may also enter this mode by virtue of a signal produced by user input. The product must wake on receiving a signal from a connected device, a network, a remote control, and/or an internal stimulus. While the product is in this mode, it is not producing a visible picture, with the possible exception of user-oriented or protective functions such as product information or status displays, or sensor-based functions.
Notes: 1. Examples of internal stimuli are a timer or occupancy sensor.
2. A power control is not an example of user input.
(c) Off Mode: The power mode in which the product is connected to a power source, and is not providing any On Mode or Sleep Mode functions. This mode may persist for an indefinite time. The product may only exit this mode by direct user actuation of a power switch or control. Some products may not have this mode.
1.4. Luminance: The photometric measure of the luminous intensity per unit area of light travelling in a given direction, expressed in candelas per square meter (cd/m2). Luminance refers to the brightness settings of a display.
(a) Maximum Reported Luminance: The maximum luminance the display may attain at an On Mode preset setting, and as specified by the manufacturer, for example, in the user manual.
(b) Maximum Measured Luminance: The maximum luminance the display may attain by manually configuring its controls, such as brightness and contrast.
(c) As-shipped Luminance: The luminance of the display at the factory default preset setting the manufacturer selects for normal home or applicable market use. The As-shipped Luminance of displays with Automatic Brightness Control (ABC) enabled by default may vary based on the Ambient Light Conditions of the location in which the display is installed.
1.5. Screen Area: The viewable screen width multiplied by the viewable screen height, expressed in square inches (in2).
1.6. Automatic Brightness Control (ABC): The self-acting mechanism that controls the brightness of a display as a function of ambient light.
1.7. Ambient Light Conditions: The combination of light illuminances in the environment surrounding a display, such as a living room or an office.
1.8. Bridge Connection: A physical connection between two hub controllers, typically, but not limited to, USB or FireWire, which allows for expansion of ports typically for the purpose of relocating the ports to a more convenient location or increasing the number of available ports.
1.9. Network capability: An ability to obtain an IP address when connected to a network.
1.10. Occupancy Sensor: A device used to detect human presence in front of or in the area surrounding a display. An occupancy sensor is typically used to switch a display between On Mode and Sleep or Off Mode.
1.11. Product Family: A group of displays, made under the same brand, sharing a screen of the same size and resolution, and encased in a single housing that may contain variations in hardware configurations.
Example: Two computer monitors from the same model line with a diagonal screen size of 21 inches and a resolution of 2,074 megapixels (MP), but with variations in features such as built-in speakers or camera, could be qualified as a product family.
1.12. Representative Model: The product configuration that is tested for ENERGY STAR qualification and is intended to be marketed and labelled as ENERGY STAR.

5. User Interface
Manufacturers are encouraged to design products in accordance with the user interface standard, IEEE P1621: Standard for User Interface Elements in Power Control of Electronic Devices Employed in Office/Consumer Environments. For details, see http://eetd.LBL.gov/Controls. In the event that the manufacturer does not adopt IEEE P1621, the manufacturer shall provide EPA or the European Commission, as appropriate with its rationale for not doing so.

6. Effective date
6.1. The date that manufacturers may begin to qualify products as Energy Star under this Version 6.0, will be defined as the effective date of the Agreement. To qualify for ENERGY STAR, a product model shall meet the ENERGY STAR specification in effect on its date of manufacture. The date of manufacture is specific to each unit and is the date (e.g., month and year) on which a unit is considered to be completely assembled.
6.2. Future Specification Revisions: EPA and the European Commission reserve the right to change this specification should technological and/or market changes affect its usefulness to consumers, industry, or the environment. In keeping with current policy, revisions to the specification are arrived at through stakeholder discussions. In the event of a specification revision, please note ENERGY STAR qualification is not automatically granted for the life of a model.

7. Considerations for future revisions

7.1. Displays Larger Than 61 in Diagonal Screen Size
It is understood that interactive displays greater than 60’ in diagonal screen size are currently available in the market and are namely used for commercial and educational purposes. There is interest in better understanding the power consumption associated with these products when tested according to the Displays Test Method and EPA and the European Commission will work with stakeholders prior to, and during, the next specification revision development process to access the information. EPA and the European Commission are in principle interested in exploring expanding the scope of products to those greater than 61’ in diagonal screen size in the next specification revision.

7.2. Touch Screen Functionality
EPA and the European Commission are committed to continuing to develop performance levels for displays that account for new features and functionality, and anticipate that displays with touch screen functionality, which are included in the scope of this specification, will become more prevalent in the market, especially among signage displays. Going forward, EPA, DOE and the European Commission will explore with stakeholders whether touch screen functionality impacts On Mode power consumption to determine to what extent the next specification development process should address touch screen functionality.

II. UNINTERRUPTIBLE POWER SUPPLIES SPECIFICATIONS

1. Definitions
Unless otherwise specified, all terms used in this document are consistent with the definitions in the International Electrical Commission (IEC) standard IEC 62040-3.
International Electrotechnical Commission (IEC). IEC standard 62040-3:2011. ‘Uninterruptible power systems (UPS) - Part 3: Method of specifying the performance and test requirements.’ Ed. 2.0.
For the purpose of this specification the following definitions apply:
Uninterruptible Power Supply (UPS): Combination of convertors, switches, and energy storage devices (such as batteries) constituting a power system for maintaining continuity of load power in case of input power failure.
2 Input power failure occurs when voltage and frequency are outside rated steady-state and transient tolerance bands or when distortion or interruptions are outside the limits specified for the UPS.

1.1. Power conversion mechanism:
(a) Static UPS: UPS where solid-state power electronic components provide the output voltage.
(b) Rotary UPS: UPS where one or more electrical rotating machines provide the output voltage.
(1) Rotary UPS (RUPS) without Diesel: A rotary UPS that does not contain an integral diesel engine to supply power to the load during an input power failure.
(2) Diesel-coupled rotary UPS (DRUPS): A rotary UPS that contains an integral diesel engine that may be used to supply power to the load during an input power failure.
(c) Power Output:
(1) Alternating Current (Ac)-output UPS: UPS that supplies power with a continuous flow of electric charge that periodically reverses direction.
(2) Direct Current (Dc)-output UPS/Rectifier: UPS that supplies power with a continuous flow of electric charge that is unidirectional. Includes both individual rectifier units for dc applications and entire dc-output UPS frames or systems, consisting of rectifier modules, controllers, and any other supporting components.
Note: Dc-output UPSs are also known as rectifiers. For the purposes of this document, the term ‘Dc-output UPS/Rectifier’ is used because a ‘rectifier’ may also refer to an Ac-output UPS subsystem.
1.2. Modular UPS: A UPS comprised of two or more single UPS units, sharing one or more common frames and a common energy storage system, whose outputs, in Normal Mode of operation, are connected to a common output bus contained entirely within the frame(s). The total quantity of single UPS units in a modular UPS equals ‘n + r’ where n is the quantity of single UPS units required to support the load; r is the quantity of redundant UPS units. Modular UPSs may be used to provide redundancy, to scale capacity or both.

1.3. Redundancy: Addition of UPS units in a parallel UPS to enhance the continuity of load power, and classified as follows.
(a) N + 0: UPS that cannot tolerate any failures while maintaining Normal Mode operation. No redundancy.
(b) N + 1: Parallel UPS that can tolerate the failure of one UPS unit or one group of UPS units while maintaining Normal Mode operation.
(c) 2N: Parallel UPS that can tolerate the failure of one half of its UPS units while maintaining Normal Mode operation.

1.4. UPS Operational Modes:
(a) Normal Mode: Stable mode of operation that the UPS attains under the following conditions:

(2) All power is derived from the energy storage system or, in the case of a DRUPS, from the integrated Diesel engine or a combination of both.
(3) The load is within the specified rating of the UPS.
(c) Bypass Mode: Mode of operation that the UPS attains when operating the load supplied via the Bypass only.

1.5. UPS Input Dependency Characteristics:
(a) Voltage and Frequency Dependent (VFD): Capable of protecting the load from power outage.
The output of the VFD UPS is dependent on changes in ac input voltage and frequency and is not intended to provide additional corrective functions, such as those arising from the use of tapped transformers.
(b) Voltage Independent (VI): Capable of protecting the load as required for VFD, above, and in addition from:
(1) Under-voltage applied continuously to the input
(2) Over-voltage applied continuously to the input
An output voltage tolerance band narrower than input voltage window shall be defined by the manufacturer. The output of the VI UPS is dependent on ac input frequency and the output voltage shall remain within prescribed voltage limits (provided by additional corrective voltage functions, such as those arising from the use of active and/or passive circuits).
(c) Voltage and Frequency Independent (VFI): Independent of voltage and frequency variations and capable of protecting the load against adverse effects from such variations without depleting the stored energy source.

(b) Dc-Dc Power Supply: A PSU that converts line-voltage dc input power to one or more dc outputs for the purpose of powering a computer server. For purposes of this specification, a dc-dc converter (also known as a voltage regulator) that is internal to a computer server and is used to convert a low voltage dc (e.g., 12 V dc) into other dc power outputs for use by computer server components is not considered a dc-dc power supply.
(c) Single-output Power Supply: A PSU that is designed to deliver the majority of its rated output power to one primary dc output for the purpose of powering a computer server. Single-output PSUs may offer one or more standby outputs that remain active whenever connected to an input power source. For purposes of this specification, the total rated power output from any additional PSU outputs that are not primary and standby outputs shall be no greater than 20 watts. PSUs that offer multiple outputs at the same voltage as the primary output are considered single-output PSUs unless those outputs (1) are generated from separate converters or have separate output rectification stages, or (2) have independent current limits.
(d) Multi-output Power Supply: A PSU that is designed to deliver the majority of its rated output power to more than one primary dc output for the purpose of powering a computer server. Multi-output PSUs may offer one or more standby outputs that remain active whenever connected to an input power source. For purposes of this specification, the total rated power output from any additional PSU outputs that are not primary and standby outputs is greater than or equal to 20 watts.

1.4.2. I/O Device: A device which provides data input and output capability between a computer server and other devices. An I/O device may be integral to the computer server motherboard or may be connected to the motherboard via expansion slots (e.g., PCI, PCIe). Examples of I/O devices include discrete Ethernet devices, InfiniBand devices, RAID/SAS controllers, and Fibre Channel devices.
I/O Port: Physical circuitry within an I/O device where an independent I/O session can be established. A port is not the same as a connector receptacle; it is possible that a single connector receptacle can service multiple ports of the same interface.
1.4.3. Motherboard: The main circuit board of the server. For purposes of this specification, the motherboard includes connectors for attaching additional boards and typically includes the following components: processor, memory, BIOS, and expansion slots.
1.4.4. Processor: The logic circuitry that responds to and processes the basic instructions that drive a server. For purposes of this specification, the processor is the central processing unit (CPU) of the computer server. A typical CPU is a physical package to be installed on the server motherboard via a socket or direct solder attachment. The CPU package may include one or more processor cores.
1.4.5. Memory: For purposes of this specification, memory is a part of a server external to the processor in which information is stored for immediate use by the processor.
1.4.6. Hard Drive (HDD): The primary computer storage device which reads and writes to one or more rotating magnetic disk platters.
1.4.7. Solid State Drive (SSD): A storage device that uses memory chips instead of rotating magnetic platters for data storage.

1.5. Other Datacenter Equipment:
1.5.1. Network Equipment: A device whose primary function is to pass data among various network interfaces, providing data connectivity among connected devices (e.g., routers and switches). Data connectivity is achieved via the routing of data packets encapsulated according to internet Protocol, Fibre Channel, InfiniBand or similar protocol.
1.5.2. Storage Product: A fully-functional storage system that supplies data storage services to clients and devices attached directly or through a network. Components and subsystems that are an integral part of the storage product architecture (e.g., to provide internal communications between controllers and disks) are considered to be part of the storage product. In contrast, components that are normally associated with a storage environment at the data centre level (e.g., devices required for operation of an external SAN) are not considered to be part of the storage product. A storage product may be composed of integrated storage controllers, storage devices, embedded network elements, software, and other devices. While storage products may contain one or more embedded processors, these processors do not execute user-supplied software applications but may execute data-specific applications (e.g., data replication, backup utilities, data compression, install agents).
1.5.3. Uninterruptible Power Supply (UPS): Combination of convertors, switches, and energy storage devices (such as batteries) constituting a power system for maintaining continuity of load power in case of input power failure.

1.6. Operational Modes and Power States
1.6.1. Idle State: The operational state in which the OS and other software have completed loading, the computer server is capable of completing workload transactions, but no active workload transactions are requested or pending by the system (i.e., the computer server is operational, but not performing any useful work). For systems where ACPI standards are applicable, Idle State correlates only to ACPI System Level S0.
1.6.2. Active State: The operational state in which the computer server is carrying out work in response to prior or concurrent external requests (e.g., instruction over the network). Active state includes both (1) active processing and (2) data seeking/retrieval from memory, cache, or internal/external storage while awaiting further input over the network.

1.7. Other Key Terms

1.7.1. Controller System: A computer or computer server that manages a benchmark evaluation process. The controller system performs the following functions:

(b) control the workload demands of the performance benchmark;
(c) start and stop data collection from the power analyser so that power and performance data from each phase can be correlated;
(d) store log files containing benchmark power and performance information;
(e) convert raw data into a suitable format for benchmark reporting, submission and validation; and
(f) collect and store environmental data, if automated for the benchmark.
1.7.2. Network Client (Testing): A computer or computer server that generates workload traffic for transmission to a unit under test (UUT) connected via a network switch.

1.7.3. RAS Features: An acronym for reliability, availability, and serviceability features. RAS is sometimes expanded to RASM, which adds ‘Manageability’ criteria. The three primary components of RAS as related to a computer server are defined as follows:
(a) Reliability Features: Features that support a server’s ability to perform its intended function without interruption due to component failures (e.g., component selection, temperature and/or voltage de-rating, error detection and correction).
(b) Availability Features: Features that support a server’s ability to maximize operation at normal capacity for a given duration of downtime (e.g., redundancy [both at micro- and macro-level]).
(c) Serviceability Features: Features that support a server’s ability to be serviced without interrupting operation of the server (e.g., hot plugging).
1.7.4. Server Processor Utilization: The ratio of processor computing activity to full-load processor computing activity at a specified voltage and frequency, measured instantaneously or with a short term average of use over a set of active and/or idle cycles.
1.7.5. Hypervisor: A type of hardware virtualization technique that enables multiple guest operating systems to run on a single host system at the same time.
1.7.6. Auxiliary Processing Accelerators (APAs): Computing expansion add-in cards installed in general-purpose add-in expansion slots (e.g., GPGPUs installed in a PCI slot).
1.7.7. Buffered DDR Channel: Channel or Memory Port connecting a Memory Controller to a defined number of memory devices (e.g. DIMMs) in a computer server. A typical computer server may contain multiple Memory Controllers, which may in turn support one or more Buffered DDR Channels. As such, each Buffered DDR Channel serves only a fraction of the total addressable memory space in a computer server.

All	Standard Performance Evaluation Corporation (SPEC) Server Efficiency Rating Tool (SERT), Version 1.0.0, Rev. Feb 26, 2013

6.1.2. When testing Computer Server products, UUTs must have all Processor Sockets populated during testing.
If a Computer Server cannot support populating all Processor Sockets during testing, then the system must be populated to its maximum functionality. These systems will be subject to the base idle state power allowance based on the number of sockets in the system.

6.2. Number of Units Required for Testing
Representative Models shall be selected for testing per the following requirements:
(a) For qualification of an individual product configuration, the unique configuration that is intended to be marketed and labelled as ENERGY STAR is considered the Representative Model.

All such representative models shall have the same Common Product Family Attributes as defined in 1.8.1.

6.3. Qualifying Families of Products

6.3.1. Partners are encouraged to test and submit data on individual product configurations for qualification to ENERGY STAR. However, a Partner may qualify multiple product configurations under one Product Family designation if each configuration within the family meets one of the following requirements:
(a) Individual products are built on the same platform, are eligible under and meet the same specific requirements in this specification, and are identical in every respect to the tested, representative product configuration except for housing and colour; or
(b) Individual products meet the requirements of a product family, as defined in Section 1.8, above. In this case, partners must test and submit data as required in Section (b).
6.3.2. Partners are required to submit a Power and Performance Data Sheet for each product family that is submitted for qualification.
6.3.3. All product configurations within a product family that is submitted for qualification must meet ENERGY STAR requirements, including products for which data was not reported.

7. Effective Date
7.1. The effective date of this Version 2.0 ENERGY STAR Computer Servers specification will be defined as the effective date of the Agreement. To qualify for ENERGY STAR, a product model shall meet the ENERGY STAR specification in effect on its date of manufacture. The date of manufacture is specific to each unit and is the date on which a unit is considered to be completely assembled.
7.2. Future Specification Revisions: EPA and the European Commission reserve the right to change this specification should technological and/or market changes affect its usefulness to consumers, industry, or the environment. In keeping with current policy, revisions to the specification are arrived at through stakeholder discussions. In the event of a specification revision, please note that the ENERGY STAR qualification is not automatically granted for the life of a product model.

8. Considerations for Future Revisions
8.1. Active State Efficiency Criteria: EPA and the European Commission intend to set active state efficiency criteria in Version 3.0 for all computer server categories in which it has enough SERT data to adequately differentiate products.
8.2. Right Sizing of Power Supplies: EPA and the European Commission will investigate opportunities for encouraging right-sizing of power supplies in Version 3.0.
8.3. Inclusion of Dc-Dc Computer Servers: EPA and the European Commission encourage manufacturers to work with SPEC to develop support for dc servers in the SERT, so that dc computer servers may be considered for qualification in Version 3.0.
8.4. Inclusion of Additional System Architectures: EPA and the European Commission encourage manufacturers to work with SPEC to develop support for architectures that are not currently supported by the SERT, but which represent a sizeable portion of the Computer Servers market. EPA and the European Commission will consider any architecture that is supported by the SERT prior to the development of Version 3.0.
8.5. Removal of Adder for Additional Redundant Power Supplies: EPA and the European Commission are aware of technology that allows redundant power supplies to be kept in standby mode and only activated when needed. EPA and the European Commission encourage the adoption of this technology in computer servers, and will investigate whether the current adder for additional redundant power supplies is still necessary in Version 3.0.
8.6. Auxiliary Processing Accelerator (APA) Requirements: EPA and the European Commission intends to revisit and potentially expand APA requirements in Version 3.0, based on APA data collected from Version 2.0 as well as the potential incorporation of APA evaluation in the SERT.
8.7. Thermal Reporting and Testing Requirements: EPA and the European Commission plans to re-evaluate current temperature reporting and testing requirements to maximize the value of the data collected for manufacturers as well as data centre operators.

Appendix A Sample Calculations

1. Idle State Power Requirements
To determine the Maximum Idle State Power Requirement for ENERGY STAR qualification, determine the base idle state level from Table 3, and then add power allowances from Table 4 (provided in Section 3.6 of this Eligibility Criteria). An example is provided below:
Example: A standard single processor Computer Server with 8 GB of memory, two hard drives, and two I/O devices (the first with two 1 Gbit ports and the second with six 1 Gbit ports).
1.1. Base allowance:
(a) Determine base idle allowance from Table 3, provided for reference below.
(b) The example server is evaluated under Category A and could consume no more than 47,0 watts in Idle to qualify for ENERGY STAR.
Category	Number of Installed Processors(# P)	Managed Server	Base Idle Power Allowance(W)
A	1	No	47,0
B	1	Yes	57,0
C	2	No	92,0
D	2	Yes	142,0
Resilient	2	Yes	205,0
1.2. Additional Idle Power Allowances: Calculate additional idle allowances for extra components from Table 4, provided for reference below.
System Characteristic	Applies To	Additional Idle Power Allowance
Additional Power Supplies	Power supplies installed explicitly for power redundancy	20,0 watts per Power Supply
Hard Drives (including solid state drives)	All installed hard drives	8,0 watts per Hard Drive
Additional Memory	Installed memory greater than 4 GB	0,75 watts per GB
Additional Buffered DDR Channel	Installed buffered DDR Channels greater than 8 channels (Resilient Servers only)	4,0 watts per Buffered DDR Channel
Additional I/O Devices (single connection speed rounded to nearest Gbit)	Installed Devices greater than two ports of 1 Gbit, onboard Ethernet	< 1 Gbit: No Allowance = 1 Gbit: 2,0 watts/Active Port > 1 Gbit and < 10 Gbit: 4,0 watts/Active Port ≥ 10 Gbit: 8,0 watts/Active Port
(a) The example server has two hard drives. It therefore is provided with an additional 16,0 watt allowance for each hard drive (2 HDD × 8,0 watts).
(b) The example server has 4 GB in excess of the base configuration. It therefore is provided with an additional 3,0 watt allowance for memory (4 extra GB × 0,75 watts/GB).
(c) The example server has one I/O card that does not qualify for an adder: the first device has only two Ethernet ports and does not exceed the two-port threshold. Its second device does qualify for an adder: the server is provided with an additional 12,0 watt allowance for the device (six 1Gbit ports × 2,0 watts/active port).
1.3. Calculate the final idle allowance by adding the base allowance with the additional power allowances. The example system would be expected to consume no more than 78,0 watts at Idle to qualify (47,0 W + 16,0 W + 3,0 W + 12,0 W).

2. Additional Idle Allowance — Power Supplies
The following examples illustrate the idle power allowances for additional power supplies:
2.1. If a Computer Server requires two power supplies to operate, and the configuration includes three installed power supplies, the server would receive an additional 20,0 watt idle power allowance.
2.2. If the same server were instead shipped with four installed power supplies, it would receive an additional idle power allowance of 40,0 watts.

3. Additional Idle Allowance — Additional Buffered DDR Channel
The following examples illustrate the idle power allowances for additional buffered DDR channels:
3.1. If a resilient Computer Server is shipped with six installed buffered DDR channels, the server would not receive an additional idle power allowance.
3.2. If the same resilient server were instead shipped with 16 installed buffered DDR channels, it would receive an additional idle power allowance of 32,0 watts (first 8 channels = no additional allowance, second 8 channels = 4,0 watts × 8 buffered DDR channels).

Appendix B Identifying resilient server class

1. Processor RAS and Scalability — All of the following shall be supported:
1.1. Processor RAS: The processor must have capabilities to detect, correct, and contain data errors, as described by all of the following:
(a) Error detection on L1 caches, directories and address translation buffers using parity protection;
(b) Single bit error correction (or better) using ECC on caches that can contain modified data. Corrected data is delivered to the recipient (i.e., error correction is not used just for background scrubbing);
(c) Error recovery and containment by means of (1) processor checkpoint retry and recovery, (2) data poison indication (tagging) and propagation, or (3) both. The mechanisms notify the OS or hypervisor to contain the error within a process or partition, thereby reducing the need for system reboots; and
(d) (1) Capable of autonomous error mitigation actions within processor hardware, such as disabling of the failing portions of a cache, (2) support for predictive failure analysis by notifying the OS, hypervisor, or service processor of the location and/or root cause of errors, or (3) both.
1.2. The processor technology used in resilient and scalable servers is designed to provide additional capability and functionality without additional chipsets, enabling them to be designed into systems with 4 or more processor sockets. The processors have additional infrastructure to support extra, built-in processor busses to support the demand of larger systems.
1.3. The server provides high bandwidth I/O interfaces for connecting to external I/O expansion devices or remote I/O without reducing the number of processor sockets that can be connected together. These may be proprietary interfaces or standard interfaces such as PCIe. The high performance I/O controller to support these slots may be embedded within the main processor socket or on the system board.

2. Memory RAS and Scalability — All of the following capabilities and characteristics shall be present:
(a) Provides memory fault detection and recovery through Extended ECC;
(b) In x4 DIMMs, recovery from failure of two adjacent chips in the same rank;
(c) Memory migration: Failing memory can be proactively de-allocated and data migrated to available memory. This can be implemented at the granularity of DIMMs or logical memory blocks. Alternatively, memory can also be mirrored;
(d) Uses memory buffers for connection of higher speed processor -memory links to DIMMs attached to lower speed DDR channels. Memory buffer can be a separate, standalone buffer chip which is integrated on the system board, or integrated on custom-built memory cards. The use of the buffer chip is required for extended DIMM support; they allow larger memory capacity due to support for larger capacity DIMMs, more DIMM slots per memory channel, and higher memory bandwidth per memory channel than direct-attached DIMMs. The memory modules may also be custom-built, with the memory buffers and DRAM chips integrated on the same card;
(e) Uses resilient links between processors and memory buffers with mechanisms to recover from transient errors on the link; and
(f) Lane sparing in the processor-memory links. One or more spare lanes are available for lane failover in the event of permanent error.
3. Power Supply RAS: All PSUs installed or shipped with the server shall be redundant and concurrently maintainable. The redundant and repairable components may also be housed within a single physical power supply, but must be repairable without requiring the system to be powered down. Support must be present to operate the system in degraded mode when power delivery capability is degraded due to failures in the power supplies or input power loss.
4. Thermal and Cooling RAS: All active cooling components, such as fans or water-based cooling, shall be redundant and concurrently maintainable. The processor complex must have mechanisms to allow it to be throttled under thermal emergencies. Support must be present to operate the system in degraded mode when thermal emergencies are detected in system components.

5. System Resiliency — no fewer than six of the following characteristics shall be present in the server:
(a) Support of redundant storage controllers or redundant path to external storage;
(b) Redundant service processors;
(c) Redundant dc-dc regulator stages after the power supply outputs;
(d) The server hardware supports runtime processor de-allocation;
(e) I/O adapters or hard drives are hot-swappable;
(f) Provides end to end bus error retry on processor to memory or processor to processor interconnects;
(g) Supports on-line expansion/retraction of hardware resources without the need for operating system reboot (‘on-demand’ features);
(h) Processor Socket migration: With hypervisor and/or OS assistance, tasks executing on a processor socket can be migrated to another processor socket without the need for the system to be restarted;
(i) Memory patrol or background scrubbing is enabled for proactive detection and correction of errors to reduce the likelihood of uncorrectable errors; and
(j) Internal storage resiliency: Resilient systems have some form of RAID hardware in the base configuration, either through support on the system board or a dedicated slot for a RAID controller card for support of the server’s internal drives.

6. System Scalability — All of the following shall be present in the server:
(a) Higher memory capacity: >=8 DDR3 or DDR4 DIMM Ports per socket, with resilient links between the processor socket and memory buffers; and
(b) Greater I/O expandability: Larger base I/O infrastructure and support a higher number of I/O slots. Provide at least 32 dedicated PCIe Gen 2 lanes or equivalent I/O bandwidth, with at least one x16 slot or other dedicated interface to support external PCIe, proprietary I/O interface or other industry standard I/O interface.

5.1.1. As-shipped Condition: Products shall be tested in their ‘as-shipped’ configuration, which includes both hardware configuration and system settings, unless otherwise specified in this test method. Where relevant, all software options shall be set to their default condition.
5.1.2. Measurement Location: All power measurements shall be taken at a point between the ac power source and the UUT. No Uninterruptible Power Supply (UPS) units may be connected between the power meter and the UUT. The power meter shall remain in place until all Idle and Active State power data are fully recorded. When testing a Blade System, power shall be measured at the input of the Blade Chassis (i.e., at the power supplies that convert data centre distribution power to Chassis distribution power).
5.1.3. Air Flow: Purposefully directing air in the vicinity of the measured equipment in a way that would be inconsistent with normal data centre practices is prohibited.
5.1.4. Power Supplies: All PSUs shall be connected and operational.
UUTs with Multiple PSUs: All power supplies shall be connected to the ac power source and operational during the test. If necessary, a Power Distribution Unit (PDU) may be used to connect multiple power supplies to a single source. If a PDU is used, any overhead electrical use from the PDU shall be included in the power measurement of the UUT. When testing Blade Servers with half-populated Chassis configurations, the power supplies for the unpopulated power domains can be disconnected (see section 5.2.4(b) for more information).
5.1.5. Power Management and Operating System: The as-shipped operating system or a representative operating system shall be installed. Products that are shipped without operating systems shall be tested with any compatible operating system installed. For all tests, the power management techniques and/or power saving features shall be left as-shipped. Any power management features which require the presence of an operating system (i.e. those that are not explicitly controlled by the Basic Input Output System (BIOS) or management controller) shall be tested using only those power management features enabled by the operating system by default.
5.1.6. Storage: Products shall be tested for qualification with at least one Hard Disk Drive (HDD) or one Solid State Drive (SSD) installed. Products that do not include pre-installed hard drives (HDD or SSD) shall be tested using a storage configuration used in an identical model for sale that does include pre-installed hard drives. Products that do not support installation of hard drives (HDD or SSD) and, instead, rely exclusively on external storage solutions (e.g. storage area network) shall be tested using external storage solutions.
5.1.7. Blade System and Dual/Multi-Node Servers: A Blade System or Dual/Multi-Node Server shall have identical configurations for each node or Blade Server including all hardware components and software/power management settings. These systems shall also be measured in a way that ensures all power from all tested nodes/Blade Servers is captured by the power meter during the entire test.
5.1.8. Blade Chassis: The Blade Chassis, at a minimum, shall have power, cooling, and networking capabilities for all the Blade Servers. The Chassis shall be populated as specified in section 5.2.4. All power measurements for Blade Systems shall be made at the input of the Chassis.

5.1.10. Input/Output (I/O) and Network Connection: The UUT shall have at least one port connected to an Ethernet network switch. The switch shall be capable of supporting the UUT’s highest and lowest rated network speeds. The network connection shall be live during all tests, and, although the link shall be ready and able to transmit packets, no specific traffic is required over the connection during testing. For the purpose of testing ensure the UUT offers at least one Ethernet port (using a single add-in card only if no onboard Ethernet support is offered).
5.1.11. Ethernet Connections: Products shipped with support for Energy Efficient Ethernet (compliant with IEEE 802.3az) shall be connected only to Energy Efficient Ethernet compliant network equipment during testing. Appropriate measures shall be taken to enable EEE features on both ends of the network link during all tests.

5.2. UUT Preparation
5.2.1. The UUT shall be tested with the processor sockets populated as specified in Section 6.1.2 of ENERGY STAR Eligibility Criteria Version 2.0.
5.2.2. Install the UUT in a test rack or location. The UUT shall not be physically moved until testing is complete.
5.2.3. If the UUT is a Multi-node system, the UUT shall be tested for per node power consumption in the fully-populated Chassis configuration. All Multi-node Servers installed in the Chassis shall be identical, sharing the same configuration.

5.2.4. If the UUT is a Blade System, the UUT shall be tested for Blade Server power consumption in the half-populated Chassis configuration with an additional option of testing the UUT in the fully-populated Chassis configuration. For Blade Systems, populate the Chassis as follows:
(a) Individual Blade Server Configuration
All Blade Servers installed in the Chassis shall be identical, sharing the same configuration (homogeneous).
(b) Half Chassis Population (Required)
(1) Calculate the number of Blade Servers required to populate half the number of Single-wide Blade Server slots available in the Blade Chassis.
(2) For Blade Chassis having multiple power domains, choose the number of power domains that is closest to filling half of the Chassis. In a case where there are two choices that are equally close to filling half of the Chassis, test with the domain or combination of domains which utilize a higher number of Blade Servers.
Example 1: A certain Blade Chassis supports up to 7 Single-wide Blade Servers on two power domains. One power domain supports 3 Blade Servers and the other supports 4 Blade Servers. In this example, the power domain which supports 4 Blade Servers would be fully populated during testing, while the other power domain would remain unpopulated.
Example 2: A certain Blade Chassis supports up to 16 Single-wide Blade Servers on four power domains. Each of the four power domains supports 4 Blade Servers. In this example, two of the power domains would be fully populated during testing, while the other two power domains would remain unpopulated.
(3) Follow all user manual or manufacturer recommendations for partially populating the Chassis, which may include disconnecting some of the power supplies and cooling fans for the unpopulated power domains.
(4) If user manual recommendations are not available or are incomplete, then use the following guidance:
(i) Completely populate the power domains.
(ii) If possible, disconnect the power supplies and cooling fans for unpopulated power domains.
(iii) Fill all empty bays with blanking panels or an equivalent airflow restriction for the duration of testing.
(c) Full Chassis Population (Optional)
Populate all available Chassis bays. All power supplies and cooling fans shall be connected. Proceed with all required tests in the test procedure as specified in Section 6.
5.2.5. Connect the UUT to a live Ethernet (IEEE 802.3) network switch. The live connection shall be maintained for the duration of testing, except for brief lapses necessary for transitioning between link speeds.
5.2.6. The Controller System required to provide SERT workload harness control, data acquisition, or other UUT testing support shall be connected to the same network switch as the UUT and satisfy all other UUT network requirements. Both the UUT and Controller System shall be configured to communicate via the network.
5.2.7. Connect the power meter to an ac voltage source set to the appropriate voltage and frequency for the test, as specified in Section 4.
5.2.8. Plug the UUT into the measurement power outlet on the power meter following the guidelines in 5.1.2.
5.2.9. Connect the data output interface of the power meter and the temperature sensor to the appropriate input of the Controller System.
5.2.10. Verify that the UUT is configured in its as–shipped configuration.
5.2.11. Verify that the Controller System and UUT are connected on the same internal network via an Ethernet network switch.
5.2.12. Use a normal ping command to verify that the Controller System and UUT can communicate with each other.
5.2.13. Install SERT 1.0.0 on the UUT and the Controller System as specified in the SERT User Guide 1.0.0.

1.2. Marking Technologies:
1.2.1. Direct Thermal (DT): A marking technology characterized by the burning of dots onto coated print media that is passed over a heated print head. DT products do not use ribbons.
1.2.2. Dye Sublimation (DS): A marking technology characterized by the deposition (sublimation) of dye onto print media as energy is supplied to heating elements.
1.2.3. Electro-photographic (EP): A marking technology characterized by the illumination of a photoconductor in a pattern representing the desired output image via a light source, development of the image with particles of toner using the latent image on the photoconductor to define the presence or absence of toner at a given location, transfer of the toner to the final print media, and fusing to cause the output to become durable. For purposes of this specification, Colour EP products simultaneously offer three or more unique toner colours, while Monochrome EP products simultaneously offer one or two unique toner colours. This definition includes Laser, Light Emitting Diode (LED), and Liquid Crystal Display (LCD) illumination technologies.
1.2.4. Impact: A marking technology characterized by the formation of the desired output image by transferring colorant from a ‘ribbon’ to the print media via an impact process. This definition includes Dot Formed Impact and Fully Formed Impact.

TT is distinguished from IJ in that the ink is solid at room temperature and is made fluid by heat.

1.3. Operational Modes:
1.3.1. On Mode:
(a) Active State: The power state in which a product is connected to a power source and is actively producing output, as well as performing any of its other primary functions
(b) Ready State: The power state in which a product is not producing output, has reached operating conditions, has not yet entered into any lower-power modes, and can enter Active State with minimal delay. All product features can be enabled in this state, and the product is able to return to Active State by responding to any potential inputs, including external electrical stimulus (e.g., network stimulus, fax call, or remote control) and direct physical intervention (e.g., activating a physical switch or button).
1.3.2. Off Mode: The power state that the product enters when it has been manually or automatically switched off but is still plugged in and connected to the mains. This mode is exited when stimulated by an input, such as a manual power switch or clock timer to bring the unit into Ready State. When this state is resultant from a manual intervention by a user, it is often referred to as Manual Off, and when it is resultant from an automatic or predetermined stimuli (e.g., a delay time or clock), it is often referred to as Auto-off.
For the purposes of this specification ‘mains’ or the ‘main electricity supply’ refers to the input power source, including a dc power supply for products that operate solely off dc power.
1.3.3. Sleep Mode: A reduced power state that a product enters either automatically after a period of inactivity (i.e., Default Delay Time), in response to user manual action (e.g., at a user-set time of day, in response to a user activation of a physical switch or button), or in response to external electrical stimulus (e.g., network stimulus, fax call, remote control). For products evaluated under the TEC test method, Sleep Mode permits operation of all product features (including maintenance of network connectivity), albeit with a possible delay to transition into Active State. For products evaluated under the OM test method, Sleep Mode permits operation of a single active network interface, as well as a fax connection if applicable, albeit with a possible delay to transition into Active State.
1.3.4. Standby: The lowest power consumption state which cannot be switched off (influenced) by the user and that may persist for an indefinite time when the product is connected to the main electricity supply and used in accordance with the manufacturer’s instructions. Standby is the product’s minimum power state. For Imaging Equipment products addressed by this specification, the ‘Standby’ Mode usually corresponds to Off Mode, but may correspond to Ready State or Sleep Mode. A product cannot exit Standby and reach a lower power state unless it is physically disconnected from the main electricity supply as a result of manual manipulation.

(b) If a product is not certain to be bundled with an automatic duplex tray, the partner must make clear in their product literature, on their Web site, and in institutional sales literature that although the product meets the ENERGY STAR energy efficiency requirements, the product only fully qualifies for ENERGY STAR when bundled with or used with a duplexer tray. EPA and the European Commission ask that partners use the following language to convey this message to customers: ‘Achieves ENERGY STAR energy savings; product fully qualifies when packaged with (or used with) a duplex tray.’

3.3.2. Typical Electricity Consumption: Calculated Typical Energy Consumption (TEC) per Equation 3 or Equation 4 shall be less than or equal to the Maximum TEC Requirement (TECMAX) specified in Equation 6.
(a) For Imaging Equipment with a Type 2 DFE that meet the Type 2 DFE maximum TECDFE requirement in Table 2, the measured energy consumption of the DFE shall be divided by 0,80 to account for internal power supply losses and then excluded when comparing the product’s measured TEC value to TECMAX. The DFE shall not interfere with the ability of the Imaging Equipment to enter or exit its lower-power modes. The energy use of a DFE can only be excluded if it meets the DFE definition in Section 1 and is a separate processing unit that is capable of initiating activity over the network.
Example: A printer’s total TEC result is 24,50 kWh/wk and its Type 2 TECDFE value calculated in Section 3.2.4 is 9,0 kWh/wk. The TECDFE value is then divided by 0,80 to account for internal power supply losses with the Imaging Equipment in Ready State, resulting in 11,25 kWh/wk. The power supply adjusted value is subtracted from the tested TEC value: 24,50 kWh/wk – 11,25 kWh/wk = 13,25 kWh/wk. This 13,25 kWh/wk result is then compared to the relevant TECMAX to determine qualification.
(b) For printers, fax machines, digital duplicators with print capability, and MFDs with print capability, TEC shall be calculated per Equation 3.

3.4. Requirements for Operational Mode (OM) Products
3.4.1. Multiple Sleep Modes: If a product is capable of automatically entering multiple successive Sleep Modes, the same Sleep Mode shall be used to determine qualification under the Default Delay Time to Sleep requirements specified in Section 3.4.3 and the Sleep Mode power consumption requirements specified in Section 3.4.4.

3.4.2. DFE Requirements: For Imaging Equipment with a functionally-integrated DFE that relies on the Imaging Equipment for its power, and that meets the appropriate maximum TECDFE requirement found in Table 2, the DFE power shall be excluded subject to the following conditions:
(a) Ready State power of the DFE, as measured in the test method, shall be divided by 0,60 to account for internal power supply losses.
(1) Sleep Mode Requirements: If the resultant power in Paragraph (a), above, is less than or equal to the Ready State or Sleep Mode power of the Imaging Equipment, then the power shall be excluded from the Imaging Equipment’s measured Ready State or Sleep Mode power when comparing to the Sleep Mode requirements in Section 3.4.4, below. Otherwise, the Sleep Mode power of the DFE, as measured in the test method, shall be divided by 0,60 and excluded from the Ready or Sleep Mode power of the Imaging Equipment for comparing to the requirements.
(2) Standby Requirements: If the resultant power in Paragraph (a), above, is less than or equal to the Ready State, Sleep Mode, or Off Mode power of the Imaging Equipment, then the power shall be excluded from the Imaging Equipment’s Ready State, Sleep Mode, or Off Mode power when comparing to the Standby requirements in Section 3.4.5, below. Otherwise, the Sleep Mode power of the DFE, as measured in the test method, shall be divided by 0,60 and excluded from the Ready State, Sleep Mode, or Off Mode power of the Imaging Equipment for comparing to the requirements.
(b) The DFE must not interfere with the ability of the Imaging Equipment to enter or exit its lower-power modes.
(c) In order to take advantage of this exclusion, the DFE must meet the definition in Section 1 and be a separate processing unit that is capable of initiating activity over the network.
Examples: Product 1 is an Imaging Equipment product whose Type 2 DFE has no distinct sleep mode. The Type 2 DFE has measured Ready State and Sleep Mode power both equal to 30 watts. The measured Sleep Mode power of the product is 53 watts. When subtracting 50 watts (30 watts/0,60) from the measured Sleep Mode power of the product, 53 watts, the resulting 3 watts is the Sleep Mode power of the product for use in the criteria limits below.
Product 2 is an Imaging Equipment product whose Type 2 DFE goes to sleep when the Imaging Equipment goes to sleep during testing. The Type 2 DFE has measured DFE Ready State and Sleep Mode power equal to 30 watts and 5 watts, respectively. The measured Sleep Mode power of the product is 12 watts. When subtracting 50 watts (30 watts/0,60) from the measured Sleep Mode power of the product, 12 watts, the result is -38 watts. In this case, instead subtract 8,33 watts (5 watts/0,60) from the measured Sleep Mode power of the product, 12 watts, resulting in 3,67 watts which is used in the criteria limits below.

3.4.3. Default Delay Time: Measured Default Delay Time to Sleep (tSLEEP) shall be less than or equal to the Required Default Delay Time to Sleep (tSLEEP_REQ) requirement specified in Table 6, subject to the following conditions:
(a) The Default Delay Time to Sleep may not be adjusted by the user to be greater than the Maximum Machine Delay Time. This Maximum Machine Delay Time shall be set by the manufacturer at less than or equal to 4 hours.
(b) When reporting data and qualifying products that can enter Sleep Mode in multiple ways, partners should reference a Sleep level that can be reached automatically. If the product is capable of automatically entering multiple, successive Sleep levels, it is at the manufacturer’s discretion which of these levels is used for qualification purposes; however, the default-delay time provided must correspond with whichever level is used.
(c) Default Delay Time does not apply to OM products that can meet Sleep Mode requirements in Ready State.

(a) Only those interfaces that are present and used during the test, including any fax interface, may be considered functional adders.
(b) Product functionality offered through a DFE shall not be considered a functional adder.
(c) A single interface that performs multiple functions may be counted only once.
(d) Any interface that meets more than one interface type definition shall be classified according to the functionality used during the test.
(e) For products that meet the Sleep Mode power requirement in Ready State, no further automatic power reductions are required to meet Sleep Mode requirements.
Equation 7: Calculation of Maximum Sleep Mode Power Consumption Requirement for OM products

Manufacturers are encouraged to design products in accordance with the user interface standard IEEE 1621: Standard for User Interface Elements in Power Control of Electronic Devices Employed in Office/Consumer Environments. For details, see http://eetd.LBL.gov/Controls.

6. Effective Date
Effective Date: The Version 2.0 ENERGY STAR Imaging Equipment specification shall take effect on January 1, 2014. To qualify for ENERGY STAR, a product model shall meet the ENERGY STAR specification in effect on its date of manufacture. The date of manufacture is specific to each unit and is the date on which a unit is considered to be completely assembled.
6.1. Future Specification Revisions: EPA and the European Commission reserve the right to change this specification should technological and/or market changes affect its usefulness to consumers, industry, or the environment. In keeping with current policy, revisions to the specification are arrived at through stakeholder discussions. In the event of a specification revision, please note that the ENERGY STAR qualification is not automatically granted for the life of a product model.

6.2. Items for Consideration in a Future Revision:
(a) Test Method Changes: EPA, DOE and the European Commission will continue to monitor the implementation of proxying capability in Imaging Equipment hardware and consider the development of a test method to determine the presence of a network proxy (e.g., one compliant with ECMA-393 ProxZzzy for Sleeping Hosts). EPA, DOE and the European Commission will also evaluate the possibility of measuring and reporting as-shipped product speed, recovery time from Sleep or Off Modes for OM products, and wakeup from Sleep Mode caused by common network events.
(b) TEC Requirements in Kilowatt-hours per Year: EPA and the European Commission have added columns to the TEC Tables expressing the requirements in kilowatt-hours per year in addition to the currently-used kilowatt-hours per week. Although this is purely informative, EPA and the European Commission will consider making this unit the only way to express TEC in a future specification revision as a way to address issues with reporting accuracy and comparisons between other ENERGY STAR products (which typically report in kilowatt-hours/year).
(c) Equipment for Printing and Scanning Media Other than Paper: EPA and the European Commission often receive questions about qualifying products that print or scan media other than paper (e.g., cloth, microfilm, etc.) and welcomes data on their energy consumption. Such data would support development of requirements for these products in a future version of the specification.
(d) Professional Products (High-speed TEC Products for Printing on Heavier, Larger Paper): EPA and the European Commission have learned that some high-speed TEC products have additional requirements for handling larger and heavier paper. EPA and the European Commission will consider separating these into a separate category in a future version of the specification.
(e) Decoupled Requirements for TEC Categories: In Version 1 and 2 Imaging Equipment specifications, EPA and the European Commission assumed that colour products would have higher TEC than monochrome products due to their additional complexity, and multi-function would have higher TEC than single-function. The TEC requirements were structured to reflect this relationship. However, EPA and the European Commission have recently learned that colour MFDs—a premium product—can incorporate energy saving features that decrease their energy consumption below that for monochrome non-MFDs. EPA and the European commission will therefore consider decoupling the TEC requirements in the future to recognize the highest performers among all TEC categories.
(f) Scope Re-evaluation: EPA and the European Commission may re-assess the current market for Imaging Equipment to determine whether the current scope of included products is still relevant and whether ENERGY STAR label continues to provide a market differentiation for all product classes included in scope.
(g) Expanding Duplexing Requirements: EPA and the European Commission may re-assess the requirements for the presence of duplexing as integral to the base product and consider how the optional requirements could be made more stringent. Changing the requirements to result in greater coverage of products with duplexing integral to the base marking engine could reduce paper usage.

(5) Measurements of accumulated energy should have resolutions which are generally consistent with these values when converted to average power. For accumulated energy measurements, the figure of merit for determining required accuracy is the maximum power value during the measurement period, not the average, since it is the maximum that determines the metering equipment and setup.

4.7. Measurement Uncertainty:
Measurement uncertainty calculations should be performed according IEC 62301 Ed. 2.0 Appendix D.
Only the uncertainty due to the measurement instrument shall be calculated.
(a) Measurements of greater than or equal to 0,5 W shall have an uncertainty of 2 % or better at the 95 % confidence level.

(b) For digital duplicators, there shall be only one original image.

7. Pre-test UUT Initialization for all products

General Initialization
Prior to the start of testing, the UUT shall be initialized as follows:
(a) Set up the UUT per the instructions in the Manufacturer’s Instructions or documentation.
(1) Accessories, such as paper source, that are shipped with the base product and are intended to be installed or attached by the end-user shall be installed as intended for the product model. Paper shall be placed in all paper sources designated to hold the paper specified for testing, and the UUT shall pull from the default paper source, using the as-shipped paper source settings.
(2) If the product is connected to a computer, either directly or via a network, during the test, the computer shall be running the newest version of the manufacturer’s default driver available at the time of testing using settings corresponding to the default settings upon shipment, unless otherwise specified in this test method. The print driver version used for testing shall be recorded.
(i) In the event that a setting does not have a default and is not defined in this test method, the setting shall be set according to the tester’s discretion and shall be recorded.
(ii) When connecting via a network and multiple computers are connected to the network, print driver settings apply only to the computer sending the print jobs to the UUT.
(3) For products designed to operate on battery power when not connected to the mains power source, the battery shall be removed for all tests. For UUTs where operation without a battery pack is not a supported configuration, the test shall be performed with fully charged battery pack(s) installed, making sure to report this configuration in the test results. To ensure the battery is fully charged, perform the following steps:
(i) For UUTs that have an indicator to show that the battery is fully charged, continue charging for an additional 5 hours after the indication is present.
(ii) If there is no charge indicator, but the manufacturer’s instructions provide a time estimate for when charging this battery or this capacity of battery should be complete, continue charging for an additional 5 hours after the manufacturer’s indication.
(iii) If there is no indicator and no time estimate in the instructions, the duration shall be 24 hours.
(b) Connect the UUT to its power source.
(c) Power on the UUT and perform initial system configuration, as applicable. Verify that default delay times are configured according to product specifications and/or manufacturer recommendations.
(1) Product Speed for Testing: The product shall be tested with speed settings in their default as-shipped configuration.
(2) Auto-off for TEC Products: If a printer, digital duplicator, fax machine, or MFD with print-capability has Auto-off capability and it is enabled as-shipped, it shall be disabled prior to testing.
(3) Auto-off for OM Products: If a product has an Auto-off Mode enabled as-shipped, it shall remain enabled for the duration of testing.
(d) User-controllable anti-humidity features shall be turned off or disabled for the duration of testing.
(e) Pre-conditioning: Place the UUT in Off Mode, then let the UUT sit idle for 15 minutes.
(1) For EP-TEC products, let the UUT sit in Off Mode for an additional 105 minutes, for a total of at least 120 minutes (2 hours).
(2) Pre-conditioning is only required prior to beginning the first test on each UUT.

8. Typical Energy Consumption (TEC) Test Procedure

8.1. Job Structure

8.1.1. Jobs per Day: The number of jobs per day (NJOBS) is specified in Table 17.
Table 17	
Number of Jobs per Day (NJOBS)	
Monochrome Product Speed, s(ipm)	Jobs per Day(NJOBS)
s ≤ 8	8
8 < s < 32	s
s ≥ 32	32

8.1.2. Images per Job: Except for fax machines, the number of images shall be computed according to Equation 9, below. For convenience, Table 21 at the end of this document provides the resultant images per job computation for each integer product speed up through 100 ipm.
Equation 9: Calculation of Number of Images per Job
NIMAGES =	1	s < 4 s ≥ 4
	int0,5× s2NJOBS	
Where:
NIMAGES is the number of images per job, rounded down (truncated) to the nearest integer,
s is the (monochrome) maximum reported speed in images per minute (ipm), calculated in section 6.1.1, of this test procedure, and
NJOBS is the number of jobs per day, as calculated per Table 17.
Test Image: Test Pattern A from International Organization for Standardization (ISO)/IEC Standard 10561:1999 shall be used as the original image for all testing.
(a) Test images shall be rendered in 10 point size in a fixed-width Courier font (or nearest equivalent).
(b) German-specific characters need not be reproduced if the product is incapable of German character reproduction.
Print Jobs: Print jobs for the test shall be sent over the network connection designated in Table 16 immediately before printing each job.
(c) Each image in a print job shall be sent separately, (i.e., all images may be part of the same document), but shall not be specified in the document as multiple copies of a single original image (unless the product is a digital duplicator).
(d) For printers and MFDs that can interpret a page description language (PDL) (e.g., Printer Command Language PCL, Postscript), images shall be sent to the product in a PDL.
Copy Jobs:
(e) For copiers with speed less than or equal to 20 ipm, there shall be one original per required image.
(f) For copiers with speed greater than 20 ipm, it may not be possible to match the number of required original images (i.e., due to limits on document feeder capacity). In this case, it is permissible to make multiple copies of each original, and the number of originals shall be greater than or equal to ten.
Example: For a 50 ipm unit that requires 39 images per job, the test may be performed with four copies of 10 originals or three copies of 13 originals.
(g) Originals may be placed in the document feeder before the test begins.
Products without a document feeder may make all images from a single original placed on the platen.
Fax Jobs: Fax jobs shall be sent via the connected phone line or line simulator immediately before performing each job.

8.2. Measurement Procedures
Measurement of TEC shall be conducted according to Table 18 for printers, fax machines, digital duplicators with print capability, and MFDs with print capability, and Table 19 for copiers, digital duplicators without print capability, and MFDs without print capability, subject to the following provisions:
(a) Paper: There shall be sufficient paper in the UUT to perform the specified print or copy jobs.
(b) Duplexing: Products shall be tested in simplex mode, unless the speed of duplex mode output is greater than the speed of simplex mode output, in which case they will be tested in duplex mode. In all cases, the mode in which the unit was tested and the print speed used must be documented. Originals for copying shall be simplex images.
(c) Energy Measurement Method: All measurements shall be recorded as accumulated energy over time, in Wh; all time shall be recorded in minutes.
'Zero meter' references may be accomplished by recording the accumulated energy consumption at that time rather than physically zeroing the meter.

9. Operational Mode (OM) Test Procedure

Measurement Procedures
Measurement of OM power and delay times shall be conducted according to Table 20, subject to the following provisions:
Power Measurements: All power measurements shall be made using either the average power or accumulated energy approaches as described below:
(1) Average Power Method: The true average power shall be measured over the course of a user selected period, which shall be no less than 5 minutes.
For those modes that do not last 5 minutes, the true average power shall be measured over the mode’s entire duration.
(2) Accumulated Energy Approach: If the test instrument is incapable of measuring the true average power, the accumulated energy consumption over the course of a user selected period shall be measured. The test period shall be no less than 5 minutes. The average power shall be determined by dividing the accumulated energy consumption by the time of the test period.
(3) If the power consumption of the tested mode is periodic, then the test duration shall contain one or more complete periods.

Notes:				
— Step 1 – If the unit has no Ready indicator, use the time at which the power consumption level stabilizes to the Ready level, and note this detail when reporting the product test data.				
— Step 4 – The Default Delay Time shall be measured starting from the completion of the job until the unit enters Sleep Mode.				
— Steps 4 and 5 – For products with more than one Sleep level, repeat these steps as many times as necessary to capture all successive Sleep levels and report these data. Two Sleep levels are typically used in large-format copiers and MFDs that use high-heat marking technologies. For products lacking this Mode, disregard Steps 4 and 5.				
— Steps 4 and 5 – For products without a Sleep Mode, perform and record measurements from Ready Mode.				
— Steps 4 and 6 – Default-delay time measurements are to be measured in parallel fashion, cumulative from the start of Step 4. For example, a product set to enter a Sleep level in 15 minutes and enter a second Sleep level 30 minutes after entering the first Sleep level will have a 15-minute default-delay time to the first level and a 45 minute default-delay time to the second level.				

10. Test Procedures for Products with a Digital Front End (DFE)
This step applies only to products that have a DFE as defined in Section 1 of the ENERGY STAR Program Requirements for Imaging Equipment.

10.1. Ready Mode DFE Test
10.1.1. Products that are network-capable as-shipped shall be connected during testing. The network connection used shall be determined using Table 16.
10.1.2. If the DFE has a separate main power cord, regardless of whether the cord and controller are internal or external to the imaging product, a 10 minute power measurement of the DFE alone shall be made, and the average power recorded while the main product is in Ready Mode.
10.1.3. If the DFE does not have a separate main power cord, the tester shall measure the dc power required for the DFE when the unit as a whole is in Ready Mode. A 10 minute power measurement of the dc input to the DFE shall be made, and the average power recorded while the main product is in Ready Mode. This will most commonly be accomplished by taking an instantaneous power measurement of the dc input to the DFE.

10.2. Sleep Mode DFE Test
This testing shall be performed to obtain the Sleep Mode power of a DFE device over a 1 hour period. The resulting value will be used to qualify Imaging Equipment products that incorporate DFEs with network-capable Sleep Modes.
10.2.1. Products that are network-capable as-shipped shall be connected during testing. The network connection used shall be determined using Table 16.
10.2.2. If the DFE has a separate main power cord, regardless of whether the cord and controller are internal or external to the imaging product, a 1 hour power measurement of the DFE alone shall be made, and the average power recorded while the main product is in Sleep Mode. At the end of the 1 hour power measurement, a print job shall be sent to the main product to ensure the DFE is responsive.
10.2.3. If the DFE does not have a separate main power cord, the tester shall measure the dc power required for the DFE when the unit as a whole is in Sleep Mode. A 1 hour power measurement of the dc input to the DFE shall be made, and the average power recorded while the main product is in Sleep Mode. At the end of the 1 hour power measurement, a print job shall be sent to the main product to ensure the DFE is responsive.

10.2.4. In cases 10.2.2 and 10.2.3, the following requirements apply:
(a) Manufacturers shall provide information on:
(1) Whether DFE Sleep Mode is enabled as-shipped; and
(2) The expected time to sleep of the DFE.
(b) If the DFE does not respond to the print request at the end of 1 hour, the Ready Mode power level measured in the test method shall be reported as the Sleep Mode power.
Note: All information specified or provided by manufacturers for product testing shall be publicly available.
