Power Over Ethernet Consortium Interoperability Test Suite version 0.1 InterOperability Lab — 121 Technology Drive, Suite 2 Durham, NH 03824 — (603) 862-0239 Consortium Manager: Technicians: Gerard Nadeau ([email protected]) Sean LaPierre ([email protected]) Andrew Losee ([email protected]) Cover Letter December 10, 2003 Dilian Reyes Linear Technology 1630 McCarthy Blvd. Milpitas, CA 95035 Mr. Reyes: Enclosed are the results from the Power over Ethernet GTP Interoperability testing performed on: Linear Technology DC671 This testing pertains to the Power over Ethernet testing that was performed during the week of November 17, 2003. There were no interoperability issues uncovered, during the testing process. If you have any questions about the test procedures or results, please contact us via e-mail at ([email protected]), ([email protected]) or by phone at (603) 862-0239. Sincerely, Andrew Losee Sean LaPierre The University of New Hampshire – InterOperability Lab Power Over Ethernet Interoperability Test Suite DUT: Linear Technology DC671 The following table contains possible results and their meanings: Result PASS FAIL PASS with Comments Warning Refer to Comments Not Applicable Not Available Not Tested Borderline Informative Interpretation The DUT was observed to exhibit conformant behavior. The DUT was observed to exhibit non-compliant behavior. The DUT was observed to exhibit conformant behavior, however this behavior deviated from previous compliant results. An additional explanation of the situation is included. The DUT was observed to exhibit behavior that is not recommended. From the observations, a valid pass or fail could not be determined. An additional explanation of the situation is included. The DUT does not support the technology required to perform these tests. Due to testing station or time limitations, the tests could not be performed, or were performed in a limited capacity. Not tested due to time constraint of the test period. The observed values of the specified parameter are valid at one extreme, and invalid at the other extreme. Results are for informative purposes only and are not judged on a pass or fail basis. Power over Ethernet Consortium 2 Power Over Ethernet Interop Test Suite The University of New Hampshire – InterOperability Lab Power Over Ethernet Interoperability Test Suite DUT: Linear Technology DC671 POINT-TO-POINT (PTP) INTEROPERABILITY TESTS: Comments on Test Procedures: Test #1.1.1 Link Speed Detection Case 1: This test entails powering on the PSE separately and then connecting the link partner. The Power Sourcing Equipment should be able to provide power to the Powered Device. A link should be established between the two devices and traffic should be able to be transmitted between them. Refer to the following tables for further information regarding the results from this test Test #1.1.7 Power Request and Application These Cases are designed specifically for devices that only support power. Case 1: This test entails powering on the DUT separately and then connecting the link partner. The Power Sourcing Equipment should be able to provide power to the Powered Device. Refer to the following tables for further information regarding the results from this test. Case 2: This test entails power cycling the Power Sourcing Equipment while the Powered Device is connected. The Power Sourcing Equipment should provide power to the Powered Device. Refer to the following tables for further information regarding the results from this test. Packet Error Ratio Estimation High Attenuation Channel: The two devices are connected to each end of the channel with a 10-meter cable. The high attenuation channel is approximately 120 meters long. A number of ICMP echo requests (Refer to the Ethernet Physical Layer Interoperability Test Suite: Appendix A Table A-1) are sent to verify that traffic can successfully be sent between the link partners. For this test event 4,680,000 64byte packets and 197,000 1518byte packets were transmitted between the link partners. The number of packets lost is noted. Refer to the following tables for further information regarding the results of this test.

High Attenuation Configuration Patch Panel 2 Meters SmartBits SMB2000 with SX-7410B 5 Meters Powered Device (PD) Endpoint Power Sourcing Equipment (PSE) 10 Meters 10 Meters 35 Meters 30 Meters 35 Meters Channel Plots Included with this report is a series of plots that provide a characterization of the channels over which the testing was performed. The plots include the following items: • Attenuation plots taken for each channel. • Near end cross talk (NEXT) plots taken from both ends of each channel (Both the DUT and the testing station). The DUT end is labeled as “Near End Crosstalk" and the testing station end is labeled as “Near End Crosstalk @ Remote”. • Return Loss plots taken for each channel, at the DUT and at the testing station. The DUT is labeled as “Return Loss” and the testing station end is labeled as “Return Loss @ Remote”.
