POE issue on HP 2910-48G-PoE+ al Switch
Hello Guys,
I have HP 2910-48G-PoE+ al switch in my network.
No device is getting Power from switch. every POE port on device is in "searching" state.
when i checked POE status on switch. it is as below :-
++++++++++++++++++++++
sh power-over-ethernet
Status and Counters - System Power Status
Pre-standard Detect : On
Operational Status : On
Usage Threshold (%) : 80
Chassis power-over-ethernet:
Total Available Power : 0 W
Total Failover Power : 0 W
Total used Power : 0 W +/- 6W
Total Remaining Power : 0 W
Internal Power
1 0W /Connected - Faulted.
External Power
EPS1 /Not Connected.
++++++++++++++++++++++++
is it POE module fault or local power supply to switch ? what other things can be verified (advise with Commands).
Thnaks in advance for your reply.

Re: POE issue on HP 2910-48G-PoE+ al Switch
This looks like a broken PoE controller. The output from our 2910 switches looks like this:
Internal Power
1 382W/POE+ /Connected.
External Power
EPS1 /Not Connected.
Check the logs and see if you find entries like these:
W 01/25/90 22:59:43 00576 chassis: 50V Power Supply 1 is Faulted. Failures: 2
W 01/25/90 22:59:44 00071 chassis: Power Supply failure: Supply: 1, Failures: 1
W 01/25/90 22:59:45 00578 chassis: Co-processor Unrecoverable fault on PoE controller 1
If so, contact HPE support. There is a lifetime warranty on these switches if you are the original owner.

Yep, a similar story here (indeed show tech all and show log would help).
