Re: when a ups doesn't help

I would have to relocate the UPS - not easy. Actually easier to relocate i5.
We are looking at that now.

You'll have to excuse me if I don't sound like an authority. I'm just trying to figure out what might work but can you reverse the order. Have I5 plugged

into the UPS and the rack power strip plugged separately into the UPS?

UPS was working. The rack power strip failed .
    i5 ---> rack power strip ----> UPS

Is redundant power available on smaller i5's ??

Wouldn't the I5 have stayed up if the UPS was working properly?

Don't see how a separate UPS would have helped here. Had the power strip
been plugged into an i5-only UPS and the monitor plugged into the power
strip you would have had the same problem, no? I see no reason to have a
separate UPS for the i5. If anything, I'd argue against it. I would want
a UPS (and probably a generator) that supported my computer room,
period. Why treat the i5 differently?

Sounds to me like the problem was a piece of faulty equipment, namely
the monitor. Had the faulty equipment been an i5 tape drive, for
example, would you be asking if you should move your Wintel servers to
their own UPS to protect them?

I would think this is a case where dual power supplies would have made
sense though. You'd have killed the power to one strip, and thus one
supply, but the other supply would have kept the i5 chugging -- of
course, that assumes you didn't plug both power supplies into the same
strip. <G>

FWIW, in the office our i5 is supported from the same UPS as our Wintel
servers and comm equipment -- but the monitor for the servers is _not_
on the UPS, but that's a UPS runtime consideration. In the data center
all our wintel servers are on the same UPS system as linux boxes, aix
boxes, comm equipment, IBM tape silos, and IBM and EMC SAN servers.
Lights, phone, end users, etc. are on the generator, but not the UPS.
