Catalyst 3560 PoE Recovery

Unanswered Question

I have a colleague with a Catalyst 3560 series PoE switch deployed. There was a power outage recently and they are telling me that when the switch loses power it automatically shuts off the poe section of the switch. They are being told that there is some kind of command or code that will turn the poe back on in this scenario. Anyone heard of this or know where we can find out about it?

I've not experienced this and I've got several WS-C3560-48PS-E deployed providing power to access points. These are at remote clinics which lose power frequently due to the midwest (US) thunderstorms.

I've never had to activate the PoE section of the switch, I'm not even sure what that is. When the power is returned, the APs boot up.

If you have access to the switch, verify the model number (show version) and verify the PoE settings (show power inline). It should return something like the following:

Interface Admin Oper Power Device Class Max

Fa0/46 auto off 0.0 n/a n/a 15.4

Fa0/47 auto on 4.4 AIR-AP1230B-A-K9 n/a 15.4
