Since the Cisco 79XX phones preceded the PoE standard, they are different--polarity is reversed.

IANAE, but as I understand the PoE devices, there are two types--one always applies -48VDC to the brown pair while the other senses (as per the PoE spec.) whether the device at the other end requires power.

I'm not willing to risk a $300 Cisco set, so I'm still using the wall wart. Is anyone providing LAN power to 79XX phones at a reasonable cost?


Please see:

I am using 3Com POE injectors (the Dumb kind) with Cisco 7960s without a problem. You need a special cable that you can build or, you can buy a PowerDSine POE injector and get the following (part PD-PS-401-5/CSCS) which will do the same thing as the cable.


To add to my confusion, the wiki page you referenced says the 7960g phones are different from the original 7960.
