What pre-standard PoE devices are supported on the Switch 2600-8-PWR (J8762A)?
• Cisco 7902G, 7905G, 7912G, 7940G, 7960G IP Phones • Cisco Aironet 350, 1100, 1200, 1230AG Access Points Cisco pre-802.3af standard phones require the use of a straight-through cable from this switch to their device (+DC voltage presented on pairs 1&2, -DC voltage on pairs 3&6). These devices are dependent on the polarity of the DC voltage (a violation of the 802.3af standard) and will not work properly if the Data Pairs (wires 1&2 and 3&6) are crossed over anywhere in the cable plant from a ProCurve Switch 2600-8-PWR switch to the device. Q: What PoE devices DON’T work? Not all PoE devices are necessarily 802.3af compliant. Early versions of IP Phones, though they may accept power over the Ethernet cable using their own Mid-Span Power devices, may only accept power over the Non-Data Pairs of wires (Cat5 cable, pins 4&5 and 7&8). The 802.3af specification clearly states that Power Devices MUST accept power over either Data Pairs (1&2 and 3&6) or the Non-Data Pairs. Furthermore, a comp
