No power in POE devices

titozep99

Our 3560G-24 switch suddenly lost POE ports (with IP phones connected to them) at the same time. In the log there is this error:

%ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error, Interface Gi0/x: Power given, but Power Controller does not report Power Good

I isolated the switch, disconnect everything and reconnect just one device for testing. I have tried some things recommended with no luck (shut down and up, change cable, IP Phone, etc, no power inline auto, etc.). Here some command outputs:

I know Pair C controls PoE and pair D GigabitEthernet. If I connect a non-poe device all appears "Normal"

I think the internal PS is faulty. Is there any additional tests or command to fix or to confirm this?

Thank you for your help.

    That's pretty old code , upgrade the code and reload if that doesn't fix it , it is RMA time then

Hold on, folks!

I've seen that error message like that, particularly on the 3560.

Can you first, DISABLE the port and reboot the switch.

After the bootup process, post the output to the command "sh post".

And then enable the port. 

Here's the output:

#sh post

I enabled the port. Error appeared again.

Post the "sh log".

If you remove the connection from the switch, do you still get a "faulty" output?
