Issue with new Cisco switches

Going through a refresh. Have new 2960 switches replacing older HP Pro Curve ones. Replaced a backbone switch yesterday that was trunked with an uplink to a switch on a different floor. The uplink would not come up from Cisco to HP. Changed port on the HP and it started working, so assumed it was the port on the HP that went bad at the wrong time. Went to replace that particular HP switch today, plugged in the uplink to the existing 2960 and no activity whatsoever. No link lights...nothing. Plug back in the old HP, uplink comes right back up. Move uplink around on the HP it gets link lights on any port. Move it back to the new Cisco and no link lights on any port at all. Had to go back to the HP switch so the location could remain online for now.

Any thoughts on this at all? I tested all the uplinks between the new switches before ever trying to install them and they all worked fine. Have you seen Cisco switches be more sensitive to line issues? This building is old. At this point we are having a vendor come out to test the line and replace to rule the line out completely before we contact Cisco.
