no link light on copier when connected through switch

A Sharp MX B401 lost network connectivity.  We tested wires and switches between it and the network drop.  We cannot get a link light unless the copier is plugged directly into the drop.  No link light when connected to a known good switch with a known good cable.  Is this a network problem or a copier problem?
When connected to the drop, it gets its IP address from an SBS2003 server and I am able to connect to the web interface, it still sends error code CE-00 when trying to scan to email.

Are you trying to connect it through a gigabit switch? I have seen many issues with printers/mfps connecting through gigabit interfaces. Try using a 10/100 switch if you have one handy.

Or force the port on that switch to 100-Half. That way the Sharp should auto-negotiate. Ideally device ports should be hard set on the switch and copier for maximum throughput.

Using 10/100 switch solved the issue.  Also, tested and labeled the cat5e cables.
