Hmmm... I have a BS350 in my office, but unfortunately I'm in Nashville
at the moment.  I'll try guessing from memory :-)

Check the configuration of the switch.  IIRC the 350 can support vlans
and can trunk the uplinks with 802.1Q tagging.  It is possible that it
is trying to tag the outgoing packets; but then hat do you mean by "no
connectivity"?  No link light?  Assume you tried reversing xmit/receive?
What are you uplinking it to?  be sure the receiving port is in
agreement regarding tagging or not.

We used the 350s for awhile in two labs, uplinking to a Cisco, no
problems.  If you're still stuck, drop me a line Friday, I'll be back
then and can pull the old 350 out of retirement for reference.
