Battery Operated Products• EPA has clarified steps to ensure a fully charged battery
prior to testing, aligning with other ENERGY STAR Test
Methods for electronics:
Battery Operated Products: For products designed to operate using
batteries either when not connected to the mains or during a power
disruption, the battery shall be fully charged before the start of testingand shall be left in place for the test. To ensure the battery is fullycharged, perform the following steps:
 For UUTs that have an indicator to show that the battery is fully charged,continue charging for at least an additional 5 hours after the indication ispresent.
 If there is no charge indicator, but the manufacturer’s instructions provide atime estimate, continue charging for at least an additional 5 hours after themanufacturer’s estimate.
 If there is no indicator and no time estimate in the instructions, but thecharging current is stated on the UUT or in the instructions, terminate
charging 1 hour after the calculated charge duration or, if none of the aboveapplies, the duration shall be 24 hours.

11

Test Configuration• To limit variation and be consistent with otherENERGY STAR test procedures, EPA requires
the length of the Ethernet cable to be between 1and 2 meters:
Ethernet Cabling: All Ethernet cables used for testing
shall meet ANSI/EIA/TIA-568 Category 5e (Cat5e)
specifications and shall be between 1 and 2 meters inlength.

Wireless Link Precedence• EPA has revised the tables for wireless testing to clarify
appropriate channel bandwidths and address theinclusion of IEEE 802.11ac:
Single instantaneous frequency band support: The first supported
wireless standard and frequency band starting from the top of Table 4 shallbe used for Access Point testing. Only one band shall be active during thetest.

WAN Link Precedence• MoCA, HPNA and WiMAX (802.16e) connection types havebeen removed from Table 6, due to limited data and inability
to test them in the current test method. These protocols
should be turned off during testing. Products that act solely as
bridges between an Ethernet network and one of the removed
protocols are now out of scope.

Definitions• Clarified the Access Point definition• Harmonized Operation Modes and States with latest
revisions to the test method• Per stakeholder suggestion, replaced “maximum raw bitrate” with “maximum PHY bit rate”:
Link Rate: The maximum PHY bit rate possible on a particular link (e.g.,
1000BASE-T Ethernet supports 1 Gb/s in each direction [2 Gb/s total]; IEEE
802.11g supports 54 Mb/s total).

• New definitions for Full Network Connectivity andExternal Proxy Capability relating to the proposedSection 3.3.3 External Proxy Allowance (to be discussed
later on in the presentation).
17Product Family• For the purpose of reducing testing burden while
ensuring representativeness, EPA has proposed thefollowing Product Family structure:
Product Family: A group of product models that are (1) made by the same
manufacturer, (2) subject to the same ENERGY STAR qualification criteria, and (3)of a common basic design. Product models within a family differ from each otheraccording to one or more characteristics or features that either (1) have no impact on
product performance with regard to ENERGY STAR qualification criteria, or (2) arespecified herein as acceptable variations within a product family. For Small

Network Equipment, acceptable variations within a product family
include:1) Color,
2) Housing, or3) Any of the functional adders specified in Table 2.

Scope• A stakeholder requested that EPA explicitly exclude fromscope equipment that contains hardware circuits that
support Internet or Ethernet security or data security
functions (e.g., Firewall, VPN, SSL,
Encryption/decryption, etc.).
• EPA has not received data to support this suggestion.
• Non-rack mounted requirement in the SNE definition
should provide sufficient separation from SNE andexcluded products covered under the large network
equipment (LNE) specification development process. To
learn more about LNE, visit
www.energystar.gov/newspecs.

19

Power Supply Requirements• A stakeholder noted that the multi-output voltage
external power supplies are not included.
External Power Supplies (EPSs): EPSs (single- and multiple-voltage) shall meet thelevel V performance requirements under the International Efficiency Marking
Protocol and include the level V marking. Additional information on the Marking
Protocol is available at www.energystar.gov/powersupplies.
i. External Power Supplies shall meet level V requirements when tested using
the Test 315 Method for Calculating the Energy Efficiency of Single-Voltage
External Ac-Dc and Ac-Ac 316 Power Supplies, Aug. 11, 2004.

• EPA is not aware of any multi-output voltage EPSs inuse with SNE but welcomes stakeholder input regarding
their inclusion.

Data Assembly• In Fall 2012, EPA received additional data tested with the draft
ENERGY STAR test method• Includes 50 new models currently available on the market from variousmanufacturers
Total: 164 models

21

Average Power Calculation• EPA has maintained the average measured power calculationand maximum average power limit calculation from Draft 1
Equation 1: Average Power Calculation (PAVG)
PAVG = Average,,___

Where:
Average[xi] = Average of terms (xi) applicable to the UUT;
PWAN_TEST = WAN test, at 1.0 kb/s (W);
PLAN_TEST = LAN test, half of available wired LAN ports populated, at 1.0 kb/s (W);
PWIRELESS_TEST = LAN test, at 1.0 kb/s (W).

Equation 2: Maximum Average Power (PAVG_MAX)
PAVG_MAX = PBASE + ∑Where:PBASE = Base Power Allowance
PADDi = Additional Functional Adders

Allowance(PADD) in watts

Notes

Fast Ethernet (100Base-T)

0.1

Allowance applied once per
port present in the UUT.

Gigabit Ethernet (1000Base-T)

0.3

Allowance applied once per
port present in the UUT.

Wi-Fi (802.11a/b/g/n)

0.7

Applied once for the UUT for
availability of Wi-Fi
connectivity.

25

Additional Functional Adders• Some stakeholders suggested the following:– Additional adders for features such as MoCA, HPNA,
integrated storage, and Voice over Internet Protocol– Wi-Fi adder applied for each Wi-Fi interface presentin the product• EPA has not received any product data that
supports developing an adder for thesetechnologies

2613

12/6/2012

EEE Allowance• EPA is proposing an allowance to encourage theadoption of EEE
Energy Efficiency Ethernet (EEE) Allowance: Small Network
Equipment products that ship with IEEE 802.3az compliant Gigabit
Ethernet ports may claim a 0.2 watt additional adder for each
Gigabit port when calculating PADD.

• If all the 4 port Gigabit Ethernet switches sold in2012 had EEE functionality, EPA estimatessavings of close to $3M annually throughreducing the power consumption between SNE and
End Point Devices.
27

External Proxy Allowance• EPA is proposing an allowance to encourage theadoption of external proxy capability– Provides the ability for End Point Devices to maintain Full
Network Connectivity while entering a sleep state– If all the desktop computers that are left on could enter low
power mode because of proxying, EPA estimatessavings of over $180M annually in the U.S.

12/6/2012

Proxy Definitions
External Proxy Capability:
The ability of an SNE device to maintain Full Network Connectivity on behalf of an End
Point Device. Must include an implementation of a standard protocol for communicating
between the host and the SNE device. Note: A known such protocol is mDNS. Waking
the sleeping host is typically accomplished by Wake-On-LAN or a wireless equivalent.

Full Network Connectivity:
The ability of an End Point Device to maintain network presence while in Sleep Mode oranother low power mode (LPM) of equal or lower power consumption and intelligently
wake when further processing is required (including occasional processing required tomaintain network presence). Presence of the End Point Device, its network services andapplications is maintained even though the End Point Device is in a LPM. From thevantage point of the network, an End Point Device with full network connectivity that is in
LPM is functionally equivalent to an idle End Point Device with respect to common
applications and usage models. Full network connectivity in LPM is not limited to aspecific set of protocols but can cover applications installed after initial installation. Also
referred to as “network proxy” functionality and as described in the Ecma-393 standard.

29

Proxy Allowance Values• EPA proposes the following levels of proxycapability and associated allowances:– Base Capability: To maintain addresses and presenceon the network while in LPM, the system handles IPv4
ARP and IPv6 NS/ND. 0.2 W– Remote Wake: While in LPM, the system is capable ofremotely waking upon request from outside the local
network. Includes Base Capability. 0.5 W– Service Discovery/Name Services: While in LPM, thesystem allows for advertising host services and network
name. Includes Base Capability. 0.8 W– Full Capability: While in LPM, the system supports
Base Capability, Remote Wake, and Service
Discovery/Name Services. 1.0 W

12/6/2012

PoE Management• EPA received feedback that a Power over Ethernet (PoE)
Supply management requirement is unnecessary because it
does not provide any significant benefit to the energy
efficiency performance of the product given the standards
already in place• Thus, EPA has removed the requirement included in Draft 1:
3.4.1 Power over Ethernet (PoE) Supply Management: All SNE capableof delivering PoE to end point devices shall be capable of disabling
PoE functionality upon user request.

31

Optional Performance Reporting•

EPA has included the option to provide additional
data to appear on the ENERGY STAR qualified
product list that may help users evaluate products
to meet specific needs and interpret energy
efficiency data:––––Ethernet Throughput
Max # of Wireless ClientsMax # of NAT Clients# of EEE Gigabit Ethernet ports – mandatory for any
products that claim the EEE Allowance in Section 3.3.2.

– Maximum External Proxy Capability – mandatory for any
products that claim the External Proxy Allowance in Section 3.3.3.

12/6/2012

Toxicity Requirements•EPA has included toxicity requirements in the ENERGY STAR PartnerCommitments
Ensure that all of Partner’s products that bear the ENERGY STAR
certification mark meet the following standard:
Product material requirements as defined in restriction of hazardous
substances (RoHS) regulations, as generally accepted. This includes
exemptions in force at the date of product manufacture: where themaximum concentration values tolerated by weight in homogeneousmaterials are: lead (0.1%), mercury (0.1%), cadmium (0.01%), hexavalentchromium (0.1%), polybrominated biphenyls (PBB) (0.1%), orpolybrominated diphenyl ethers (PBDE) (0.1%). Batteries are exempt.
Notes:• The explicit intention is to harmonize with EU RoHS.
• For purposes of ENERGY STAR third-party certification, these requirements
shall not be reviewed when products are initially qualified nor during
subsequent verification testing. Rather, EPA reserves the right to request
supporting documentation at any time.
