There are always bad chips and bad power supplies out there, stuff
that works until the box warms up. You want to plg into the
physical console and see if there's any action there, leave something
plugged into as it happens again.

Ports are typically in groups, if you see n in a row crap out, it's probably
a bad chip in there, but you need to look at the actual status as it dies
or post-mortem to try to sort out what category of problem you're looking
at. Dunno what the warranty is in 29xx's some of the newer switches are
"lifetime", and we've had 35xx's die and get replaced with no hassles.
