Cisco 7960 is not booting with PoE port

Unanswered Question
Nov 26th, 2007


I have Cisco 7960 ip phone, i have connected that in a PoE port, the phone doesn't boot, so what i use to do is, i use a power adaptor, then the ip phone bootz after the ip phone is booted completely, i remove the power adaptor, the ip phone functionz normally, this practice i am doing it when ever i switch OFF & switch ON the ip phone. I also tried connecting to the existing working IP phonez which doesn't even require a power adaptor for booting. those phones works perfectly, i tired replacing with this ip phone on that, the problem is same.

I have this problem too.

No enough power on the 3com switch...

During start up, it will require a lot of power, as compare to running in operation mode

Actually the reason is that the 7960 is a pre-standard PoE phone, so called cisco PoE.

As fa as I'm aware, the 3com switch doesn't supports cisco PoE.
