I have found these large UPS systems use the network to signal a shutdown
for PC servers. Granted that this doesn't work for the iSeries yet (that I
know of).

Just the controlled shut down part. How will the other 20 servers be
signaled to shut down when the power fails and how long do they have to
shut down before the UPS goes kirplunk.

Do you have such communication with the current UPS and your iSeries?

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

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.
