A digital signature helps to ensure the authenticity of the document, but only in this digital format. For information on how to verify this document’s integrity proceed to the following site: http://www.iol.unh.edu/certifyDoc If the document status still indicates “Validity of author NOT confirmed”, then please contact the UNH-IOL to confirm the document’s authenticity. To further validate the certificate integrity, Adobe 6.0 should report the following fingerprint information: MD5 Fingerprint: A569 F807 031D B1EC E509 4110 95E3 5362 SHA-1 Fingerprint: F007 7D91 2FAA A22C A3D9 F93F 05AC 09DB E219 84B2 Result Key The following table contains possible results and their meanings: Result PASS PASS with Comments FAIL Warning Informative Refer to Comments Not Applicable Not Available Borderline Not Tested Interpretation The Device Under Test (DUT) was observed to exhibit conformant behavior. The DUT was observed to exhibit conformant behavior however an additional explanation of the situation is included, such as due to time limitations only a portion of the testing was performed. The DUT was observed to exhibit non-conformant behavior. The DUT was observed to exhibit behavior that is not recommended. Results are for informative purposes only and are not judged on a pass of fail basis. 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. The observed values of the specified parameters are valid at one extreme, and invalid at the other. Not tested due to the time constraints of the test period. UNH-IOL PoE Consortium 2 Report Rev. 1.0 Interoperability Test Suite v2.3 Report DUT: DC981A/B, LTC4263 Endpoint PSE Test Setup Testing Equipment Spirent Smartbits 2000 Used to Source Packet Traffic Testing Configuration: UNH-IOL PoE Consortium 3 Report Rev. 1.0 Interoperability Test Suite v2.3 Report DUT: DC981A/B, LTC4263 Endpoint PSE Test #1.1.1 Link Speed Detection Case 1: This test entails powering the DUT with the link partner disconnected until the DUT has fully booted. The link partner is connected via a high attenuation cable plant. Auto-negotiation, if supported, should result in a connection at common optimal values for both the PD and the PSE. The DUT and link partner should be able to send and receive packets. Please refer to the following pages for the results of this test. Case 2: This test entails powering the DUT with the link partner connected via a high attenuation cable plant. Auto-negotiation, if supported, should result in a connection at common optimal values for both the PD and the PSE. The DUT and link partner should also be able to send and receive packets. Please refer to the following pages for the results of this test. Test #1.1.3 Packet Error Ratio Estimation High Attenuation Channel: The two devices are connected to each end of the channel with a 5-meter cable. The high attenuation channel is 125 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. The number of packets lost is noted. Refer to the following tables for further information regarding the results of this test. Low Attenuation Channel: The two devices are connected to each end of the channel with a short 5-meter cable. The low attenuation channel is 10 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. The number of packets lost is noted. Refer to the following tables for further information regarding the test results. Test #1.1.4 Endurance Stress Test This test is designed to verify that no obvious buffer management problems occur when directing a large volume of traffic with minimum IPG at the DUT. This test is informative only and is designed to verify that the DUT has no obvious buffer management problems. The DUT is attached to a sourcing station that is capable of sending an appropriate number of 64-byte ICMP echo requests with a minimum IPG of 96BT (Refer to the Ethernet Physical Layer Interoperability Test Suite Table 1-6). The DUT does not have to respond to all of the requests but the test should not cause any system failures. Refer to the following tables for further information regarding the results of 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. UNH-IOL PoE Consortium 4 Report Rev. 1.0 Interoperability Test Suite v2.3 Report DUT: DC981A/B, LTC4263 Endpoint PSE 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”. Test Matrix The matrices are divided into sections according to the type of device being tested against. The first matrix contains four columns: • The manufacturer and name of the device being tested against. • Results of link speed detection testing. • Results of the packet error ratio test over a high attenuation Category-5 compliant channel at 60°. • Results of the packet error ratio test over a low attenuation Category-5 compliant channel at 60°.
