Team,
I have one Cisco switch 4506 series (Cisco WS-C4506-E) chassis switch. Suddenly my IP phones are stop working but data is working fine. So I have checked and found my ip phones are not powering on means my one of module POE stops working. I have 6 module in that switch and POE is stop working in one of the module because of my ip phones stops working.
Can you let me know why its happen suddenly and what is the main reason for this and how can I stop in future.
Thanks
Prashant

Hi Prashant,
If u have any spare chassis, you can check the status of this faulty module for POE on that.
Do u have any output of the above commands when module went faulty so that something can be looked into?
