PoE Issue ICX 6430C12

New Contributor

Hey Guys,

Appreciate this is an old switch and don't suspect anyone to spend much time helping me. I've got a C12 Brocade which I acquired some years back. I just use it for LAB purposes, however I noticed today I tried plugging in a test phone and it will not power via PoE (first 4 ports) I'm running the latest Image and Boot for this model.


See below output for port config and inline power. (Troubleshooting steps is rebooting switch, disable renabled of port, set PoE Class as 1 on the port as this is a Cisco phone. Also I have re-installed the PoE firmware.

Is there anything useful in 'show log' when the POE devices try to come up? It looks like you have done most of the main troubleshooting steps already. POE firmware shows intact, so it is a bit interesting that POE is not working.
