[cisco-voip] PoE Phone Problem

[peter.perreault at thomson.com]

It could also be an issue with the port.  (Sorry if you've already ruled
this out)  I've experienced switches turning POE off on individual ports
once a non POE device was connected to the port.  You have to manually
enable POE on these ports to bring it back up.  There's a show command
that will indicate if POE is on or off on switch ports.

I am presuming you have tried placing these phones in the locations of
existing, working phones to ensure it is not a cabling issue. If not,
then do so. We need to find out if it is a phone or cabling issue.

If they do not power up at the other position, then it is a dead phone,
RMA it.

If they do, then we have a cabling issue of some sort. Is it possible
we have a non-POE switch between there and the MDF?

We could also have a crushed cable, a really long run, etc... If it is
just a power issue (good ethernet, bad power), then plug it in there
and use a power brick to power up the phone...
