That is a broken DEQNA/DELQA cabinet kit. There may be a loose wire in the 
connector harness or a bent pin or something. When not connected to the 
network the _only_ message you will get in a system that is working 
correctly is "no carrier".

An alternative is that you've used a vampire tap and have screwed up the 
tx/rx pairs somehow such that the transmit data is feeding back into the 
receive side. Very unlikely however.

Final possibility you aren't using a MAU cable, instead you've used a 
generic 15 pin PC joystick type cable and that just won't work.
