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

We thought about propane. However we determined that a generator capable
of running the whole building would eat a tank of propane in relatively
short order.

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






There's no harm in keeping your existing UPS and feeding it from the
protected circuit serving the entire room. In the event of failure of
the main protected circuit, the 520 UPS will take over and provide for
an orderly shutdown. I'm assuming that you have a signal cable attached
from your UPS to the 520 and that you have configured what actions to
take when a failure occurs.

Keep in mind that your 520 is useless without extending protection to
the system console and to the routers and switches that allow users to
access it.

We have a large UPS serving the entire computer room backed up with a
diesel generator supplied by an underground fuel tank. We can run
indefinitely on auxiliary power. The bulk of our users are at remote
sites and would be unaware that a utility power failure had occurred.

BTW, it's a good idea to have your auxiliary I/O devices, i.e., tape and
optical, and at least one printer on the protected circuit.

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.
