Unbelievably, the cable run was OPEN on 2 of its wires. Had the network boys come fix it and it worked instantly after that. Not sure how that happened, as no one usually is in the server room behind the patch panel... but someone had to have loosened it. Thanks to all that replied. Good guesses.

I have an HP LaserJet M401N, brand new out of the box. Its set to DHCP. Refuses to grab IP on this 1 certain wall jack. I plug a laptop into the same wall jack and immediately get IP and internet connection. The M401N is at its latest firmware. Have done all the usual stuff: reboot printer several times, shutdown and pull power from printer, tried various ethernet cables at both ends of the LAN drop.... Laptop gets 1000mbps connection, but Printer doesn't get IP at all. I have no idea what could be causing that. Any suggestions?
