Currently I'm the gopher on a problem with our office network. The
young guy always does the research and the old guys get the praise...
at least i'm learning.

We have a stack of 5 Nortel 450-24t's with a HP procurve 2524 plugged
in with a Cat 5 cable. All was working until earlier this week when
*BAM* we got nothing across our 3 remote locations and our main office.

After playing we've found that one of the 450's (that the 2524 was
plugged into) froze up the stack. It seems to work fine now as long as
long as we keep that 2524 unplugged. Every time we plug that guy in we
freeze the stack again.

What would cause this situation?
Does anyone know of where I can find a manual for the 450-24t?
Thanks for your help,
The Gopher

Broadcast storms can sometimes cause stacks to freeze or lock up their
trunk ports. We had a PC cause this from broadcasting (virus
infected). Without knowing the all details it's hard to tell for sure.
Have you tried researching the 2524 closer?
