OK so I'm not sure if I am going down the right path, but I figured I'd post this here.

I have a location running Cisco 7960-62 model phones, all connecting back to a Cisco 2960S ( WS-C2960S-24PS-L   12.2(55)SE3           C2960S-UNIVERSALK9-M).

On gi1/0/21 I have a Cisco 7960 that works fine, but the location is looking to play musical chairs. In this case if I move a 7960, 61, 62 none of those phones will power on. I plug the original phone back in, and it works just fine. I go directly from the phone > switchport and it powers on without an issue (the one I need to move).

I see these errors in the log

Apr 29 13:44:59: %ILPOWER-7-DETECT: Interface Gi1/0/21: Power Device detected: Cisco PD
Apr 29 13:44:59: %ILPOWER-5-IEEE_DISCONNECT: Interface Gi1/0/21: PD removed

Here's the config on that port, which mirrors every other port for end-user devices. What am I missing?

Yes, I will try this out tomorrow morning when the user is not connected. Then I will have them swap phones and see what happens. I will report back then! Thank you.

Are  you saying the phone, if plugged DIRECTLY into the switch, will work on that port, but not at the workstation?  If so, there may be a cabling issue.  Some of the Gig-capable phones will require all 8 pins; and possibly the older phone may NOT be gig-capable, so it isn't an issue.

If this IS the case, get the cabling corrected; or if 100 Meg is OK, some switches will accept "speed auto 10 100" to limit negotiation to 100 Meg (and only needing the standard 4 pins, not all 8).

Yes that is correct, but if I put the original phone back to the desk and go into the data port that phone powers on and registers for me. All other phones I have tried fail to power on and produce that error I posted above. 

All of our phones are 10/100.
