Please see: http://www.voip-info.org/wiki-Cisco+POE 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. -- Vice President of N2Net, a New Age Consulting Service, Inc.
