3560PoE Puzzler..Phone doesn't power up but Access Point does

jasosan22 · ‎02-13-2008

Have a 3560PoE enabled switch. When we plug a 802.3AF phone in it won't power up but if I plug a Cisco AP point in it will power up the port on the switch. Anyone know whats going on? Command line (port configuration) to fix this?

What model Access Point and Phone are you using?

Thanks for the sheet. I found this...

The Catalyst 3560G does not provide inline power to an IP phone connected to a port where a non-powered device was previously connected and unplugged from the port. This problem occurs with Poe settings of both auto and static on the port. This issue can also occur in 3750 Series Switches. It has been identified in Cisco bug ID CSCsc10999 ( registered customers only) ..

The workaround is to issue shutdown/no shutdown on the port. Then, the switch provides power to the IP phone. This issue has been resolved in Cisco IOS Software Release 12.2(25)SED1.

Right on.

Did that fix it?
