Problems with the cable maybe? 1000Base-T needs all 8 wires.

We have used these switches previously and haven't had problems
connecting anything to the copper ports, neither on the 3550-12T or the
3550-12G.

Does a loopback jack make the switch link up? Does connecting two ports
on the same switch with eachother?

You can load 12.2(52)SE on them, even though it's not supported. I'm
positive it wouldn't solve your problem though.
