Thanks for the reply, I've tried the switch and I get the green light on
both interfaces when I select them. The AUI-10baseT transceiver also
shows link active so power is getting to the AUI port.

I should have been more specific, the terminator is a T-piece and two
terminators.

I found a web site which listed a lot of the ROM test routines
(www.q.dyndns.org/~blc/DS3100/3100test.html) but I can't get any of them
to run on my 3100, the console just hangs. On my 2100 (which passes its
self-test) they work as described. Having test routines which don't work
if the self-test fails seems like a bad idea but that is the only
difference I can see between the two machines. Is there anything else
that would stop the test routines running?

Thanks,
George
