RE: Should we put the system i on a UPS for the entire room?

We have all 25 servers and one of our 520 on a APC LX1600 then wired to a
gas generator that we test quarterly. We un-wired the 520 to the APC
because we keep getting emergency shutdown do to self test and line
conditioning events. The servers are the same way. We have 2.5 hours on
battery and unlimited generator time or until we run out of natural gas.
When we have an power outage our on call person is paged and dispatched.
We have two sites like this. We test this process every year just before
spring and have not any issues. Since we load test the generator annually
for the past 2 years.

Thank You,
Ed

We have two UPS's here. I inherited it all but our 810 is on one and
everything else (2 Windows servers and all the network equipment, etc.)
are
on the other.

If your keep your 520 and network folks separate might make sense to keep
it
the way it is so if they are messing with their UPS or there is an issue
with it, it doesn't impact the 520 and vice versa ?

Our network people are getting a quote on putting the server room on one
UPS
which will feed the entire circuit going into the server room. This
includes our IBM 520 which is currently connected to a Powerware 5125 UPS
still under warranty. The room will not have a generator. From the
iSeries
side of things, I don't see any advantage to going to a UPS that will
protect 20 other servers.

What precautions do the network guys need to take with respect to the IBM
520? That is, are there any unique UPS requirements for a 520 server
versus, let's say a Dell server?

Thanks in advance.
