GSM5212P

I fixed the issue - but not exactly sure why it happened.

I bought the switch used and it was running firmware: 9.0.2.15.

First thing I did was upgrade to 10.0.2.26 before even trying POE.

I noticed some errors during startup related to: hpc_poe_platform saying POE controller requires programming.

So I reverted back to 9.0.2.15 and everything worked.

I upgraded to 9.0.2.18 and it worked.

Then to 10.0.1.21, finally back to 10.0.2.26 and POE still working and no errors on startup.

So either I shouldn't have jumped directly from 9.0.2.15 to 10.0.2.26, or else something went wrong with the original upgrade. I didn't see anything in the release notes about

prerequisite firmware to get to 10.2.26.

If an IP phone works normally between intermittent reboots, the problem could be related to PoE or an electrical connection in the cable. It could also be caused by a temporary loss of connectivity between the IP phone and the call manager. Burger King Survey
