[j-nsp] EX8200 power supplies taking down an entire 208v circuit

[Morgan McLean]

Hi everyone...

I have a troubling problem. We run a couple EX8208's, and have a mix of
1200, 2000 and 3000w PSU's in use. So far within the past ~60 days, we have
had 2 out of a total of 12 PSU's running have a failure. Unfortunately,
thats not the problem.

The problem is, when these PSUs die, they're taking out our entire circuit.
A 20A 208v circuit, completely popped. Is this normal behavior when a PSU
dies? We've had plenty of other units' PSUs go bad, and never experienced
something like this. Its been different circuits in our two network cabs,
and both weren't very loaded up last we checked before they popped. Usually
just a couple amps worth.

Any ideas?

Thanks,
Morgan
