We are runing several different types of C-6500's, all recently upgraded to s72033-ipservicesk9-mz.122-33.SXI9, the 7945 phones are running SCCP45.9-2-1S.
Randomly phones accross several switches, no common switch, port or card, will lose power, but the port for that switch still shows up/up. This is resolved by reseting the card and turning off port security or just resetting the card. Power allocation is not the issue, there is more than required. Below is what we see when one of the phones is off. This does not appear to happen to a phone twice, once this is done it seams to stay up, but it will then happen to another phone or group of phones.
Gi1/0/4 auto on 15.4 Ieee PD 3 30.0
The only change made has been the IOS update, everything else is as it has been prior to the upgrade.
Thanks ahead of time for any assistance.
