SG500 - Issues with PoE

Hola, I've 3 switch units of the same model, 2 of them presents the same issue.

The PoE devices I plugged in them aren't powered.

Checking the switches via CLI I could see this:

------------------------------------------------------------------------------------------------

ARBUEDSW0-2#show power inline

Port based power-limit mode

Inrush Test: Enable

Legacy Mode: Enable

Unit Power Nominal Power Consumed Power Usage Threshold Traps Temp (C)

----    -------      -------------   ------------------ --------------- --------- --------

1        On      375 Watts         0 Watts     (0%)              95           Disable    37

Port Powered Device State Status Priority Class

-------- -------------------- ---------------- ------------ -------- ---------

gi1/1/1                          Auto Fault low class4

gi1/1/2                          Auto Fault low class4

gi1/1/3                          Auto Fault low class4

gi1/1/4                          Auto Fault low class4

 

and this:

ARBUEDSW0-2#show pow inl gi1/1/1

Port Powered Device State Status Priority Class

-------- -------------------- ---------------- ------------ -------- ---------

gi1/1/1 Auto Fault low class4

Time range:

Power limit: 30.0 W

Inrush Test: Enable

Legacy Mode: Enable

Port Status: Port is off - power budget exceeded

Overload Counter: 0

Short Counter: 0

Denied Counter: 0

Absent Counter: 0

Invalid Signature Counter: 0

 

The power consumption is zero and all the ports have PoE status = Fault by the same reason: power budget exceeded.

Due it's happens to 2 switches at the same time I'm suspecting of a wrong setting but I can't find it.

Please advise a way to troubleshoot this issue.

Thanks in advance

That sounds like a hardware

That sounds like a hardware issue (I assume you have tried giving the switches a power cycle).  I'm guessing a PoE power supply has failed.
