30、tected Access 7 CEA-2049 7 Test Environment A) Test Setup and Instrumentation: Test setup and instrumentation for all portions of this procedure shall be in accordance with the requirements of IEC 62301, Ed. 2.0, “Household Electrical Appliances Measurement of Standby Power”, Section 4, “General Con
31、ditions for Measurements”. In the event of conflicting requirements, the ANSI/CEA-2049 test method shall take precedence. B) Input Power: Input power shall be as specified in Table 1. Testing shall only be required at the input power for the applicable market(s). Table 1: Input Power Requirements Ma

33、ature: Tests shall be carried out in a room where the air speed surrounding the unit under test (UUT) is = 0.5 m/s, and the ambient temperature is maintained at 23 5 C throughout the test. There shall be no external cooling of the UUT such as by use of separately powered fans, air conditioners, or h
34、eat sinks. The UUT shall be conditioned, rested, and tested on a thermally non-conductive surface. A readily available material such as Styrofoam will be sufficient. D) Relative Humidity: Relative humidity shall be from 10% to 80%. 8 Test Configuration 8.1 General A) As-shipped Condition: Products m
35、ust be tested in their “as-shipped” configuration. For products that offer a choice of user-configurable options, all options shall be set to their default condition, unless otherwise specified in this test procedure. B) Test Procedure Order: All portions of this test method shall be followed in the
36、 order in which they are written. C) 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 testing and shall be left in place for the test. To ensure the
37、battery is fully charged, perform the following steps: 8 CEA-2049 a. 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 is present. b. If there is no charge indicator, but the manufacturers instructions
38、 provide a time estimate, continue charging for at least an additional 5 hours after the manufacturers estimate. c. If there is no indicator and no time estimate in the instructions, but the charging current and rated charge capacity are stated on the UUT or instructions, calculate the test duration
39、 as the longer of 24 hours or: Duration (hours) = 1.4 * RatedChargeCapacity(Ah) / ChargeCurrent(A) + 5 d. If none of the above methods are available, the charge duration shall be 24 hours. D) Power Save Modes: If any power reduction features are supported by the UUT, such features may be enabled dur
40、ing testing in both the UUT and test equipment, provided that all enabled features are disclosed along with reported test results. 8.2 Supplied Power Configuration This procedure only covers devices that can be powered by AC as-shipped. Power of the UUT shall be measured and tested between the AC po
41、wer source and the UUT. Note: The UUT can be powered in three ways: (a) using an internal power supply, (b) using a power adapter for standard DC (e.g., Power over Ethernet or USB), or (c) using a power adapter for non-standard DC (e.g., AC-DC wall adapter). Devices powered by standard DC and not sh
42、ipped with a power adapter are not covered. 8.3 UUT Interface Configuration The UUT will support some combination of interfaces, including WAN/uplink interfaces, wired LAN ports, wireless LAN interfaces, analog telephony interfaces, peripheral interfaces, etc. For testing, these interfaces shall be
43、connected as described in this section and its subsections. Overview of Interface Configuration: WAN/uplink interface - single interface connected Wired LAN ports - for each LAN interface type, connect N/2 (rounded up) ports (where N is the number of ports of the type) to an active end-point. The re
44、maining N/2 (rounded down) ports are not connected. 802.11 wireless - single test client associated Peripheral interfaces (e.g., USB, eSATA, SD card, analog audio) - not connected POTS (telephony) ports - active but no handsets connected Other wireless interfaces (e.g., Bluetooth, ZigBee, Z-wave) in
45、 default as-shipped configuration, no client devices associated. Connected interfaces shall be tested in a condition in which they are active and available to function in their normal, default and/or typical capacity of forwarding or otherwise processing network traffic. The tester shall verify that
46、 the UUT is capable of this function. The ability of an interface to pass IP traffic is sufficient to verify an interface is active and available. 9 CEA-2049 8.3.1 WAN/Uplink Interface Configuration A) If the UUT offers more than one WAN connection option, the UUT shall be configured using the first
47、 available WAN connection presented in Table 2, from top to bottom. Only a single WAN port shall be connected. B) The WAN connection shall be configured to operate at the maximum possible speed. A link that can dynamically change the speed through activity detection is acceptable. Table 2: WAN/Uplin

The UUT shall
49、be tested with wired LAN ports in their default as-shipped configuration. Default settings shall not be modified, unless otherwise specified in this test method or if no default setting exists. Any features that require configuration prior to the UUT functioning (e.g., required setup before use as indicated in a reference manual) shall be configured per the following requirements. If additional required settings are not listed below, the setting type and option shall be recorded in the t
