    It appears that the phone is not making a DATA connection to the switch, but is getting power. I am thinking it is a bad patch cable, with a faulty single cable or pair.
    Check the phone documentation – I would think that the phone would display something to indicate that there is a problem. The Cisco IP phones will display the dreaded “Ethernet Disconnected” in the scenario that you described.

    I can’t tell you how much time that I’ve spent fixing shoddy wiring while rolling out new phones. My favorite is when you rip the jack apart to find that the “electrician” stole the POE pair to run a an analog handset over the same cable. Sure, the PC will work fine, but the phone not so much

    Yep, verified as a bad jack. Had a user at the office assist me, plugged it directly into the switch and it was up and rolling.
    Moved it to a known working jack, and same thing.

    Thanks guys
