Hi All,
I have an issue in my site where 15 phones stopped working suddenly. The phone is not even getting the power, other 40 phones in the same switch are working good. Here is the logs from the switch
Mar 27 07:48:29: %ILPOWER-7-DETECT: Interface Gi1/35: Power Device detected: IEEE PD
Mar 27 07:48:32: %ILPOWER-7-DETECT: Interface Gi2/41: Power Device detected: Cisco PD
Mar 27 07:48:32: %ILPOWER-7-DETECT: Interface Gi1/36: Power Device detected: IEEE PD
Mar 27 07:48:37: %C6K_POWER-SP-4-PD_NOLINKUP: The device connected to 2/41 is powered up but its link is not up in 5 seconds. Therefore, power is withdrawn from the port.
When we unplug the phone and plug it back it started working. Can anyone suggest what is happening here?
Thanks.

I'd guess either a faulty network lead somewhere, or the phone has a fault.

Hi Aman,
We have problems with 7962 and 7942 phones. I tried running the command # sh power inline
Seems either phone is not accepting power from the switch or switch has fault.

Hi Lajith,
In your post, u mentioned that when u un-plug and plug the phone, it works.
If u have power CUBE, can u try phone with it ?
after u run the command , u can check power available/used /remaining.
