I've got a stack of 2 new Catalyst 3750 V2 48 ports PoE.All the ports are configured to support ip phones + pc (switchport access vlan X + switchport voice vlan Y)
My problem is if I connect one or more Ip Phone model 7960G tey're not powered by the cat 3750 PoE, but if I connect another type of ip phone (7912,7961,7960) they're a rightly powered by the PoE of the catalyst 3750 V2.
If I connect the 7960G to an old 3750 (non V2) it works perfectly.
The Cat 3750 V2 are running with an IOS ver 12.2.(50)SE and I'm going to update to 12.2.(53)SE to try to fix this issue.
Does anyone have an idea about how I can fix this issue?
