Ok, I changed the 3com switch to 10hd only, on that port. Still no go.

Yes, I have tried the Linksys 10/100 switch. It won't work alone. As I have a few more devices from time to time that we hook up, I needed more ports than what I have on the Linksys 4-5(5 being uplink). So I was using the Cabletron with all my 10baseT and uplinking to the Linksys. I have been using that for the Empeg all this time. Now that I have an 10/100 autosensing switch with more ports I want to replace the Linksys and the cabletron with the 3com.

P.S. I am using a cross-over cable from the Cabletron to the 3com as neither one has a dedicated uplink port. I don't see a problem with that, do you?
