Need Help...
I have been experiencing issue with POE on several of my switches where for what ever reason the module stopped providing POE to the ports.
I tested POE on five other ports on the module with a Cisco IP phone 7965 and no luck not providing POE. I even tried it with Aruba wireless POE device and I got the samething, no power. I have been expereincing the same issue with two more switches and the only was i was able to resolve the issue was to reset the module. The first time I hard reset the card and fixed the issue, the second time around I did a soft reset and it fixed the issue as well.
I was just wondering if any one has expereinced the same thing and if there is a fix for it.
Thanks, Any help would be greatly appreciated.
Jack.

Try with power inline static under interface and shut/no shut interface, otherwise module is faulty. you need to raise RMA

Thanks for repluying.
what is power inline static do?
02-08-2012 06:35 AM
It define the power for the port instead of auto negotiating and rrquest for power grant.

The weird thing with this is when I do show power inline mod 6 command it shows as if there was a POE device connected to g6/48 which there is no device connected to it.

I tested POE on five other ports on the module with a Cisco IP phone 7965 and no luck not providing POE. I even tried it with Aruba wireless POE device and I got the samething, no power.
Can I recommend something? Can you kindly plug the 7965 DIRECTLY to the switch port? If it lights up, then I have a fairly good idea where the problem is. If it doesn't then I want to ask if you are willing to eliminate a Layer 1 issue.
Before we proceed, I would like to issue a DISCLAIMER. The TDR process for a 4500 is taken from the pages of the 6500. This means that the TDR result for the 4500 is NOT VERY ACCURATE.
Here's how it works:
1. Command: test cable tdr interface Gi 6/48;
2. Wait for about 60 seconds;
3. Command: sh cable tdr interface Gi 6/48;
4. Please post the output.
I know that it takes at least 60 seconds for the TDR of the 4500 to complete (while the cheaper and less powerful 2960/2960G/2960S, 3560G/3560E/3560X and 3750G/3750E/3750X takes only 5-7 seconds).
I await for your result.
