We run lasers on UPSs. They just need to be big enough. I think we use APC
2200s for each one.
Generators are a pain, especially for a small application like that, and you
STILL need something to cover the startup time of the genny. We have a 48Kw
here and it takes 12-16 seconds to start. The UPS keep everything up in the
meantime.

Subject: UPS, generators and such
All,
Our IBM i is in the cloud, so the UPS we have is now way oversized.
Liebert Nfinity installed in 2004. It's had batteries replaced, etc and
served us well during the 2-hour power outage yesterday. But seriously, we
don't need 180 minutes run time. :) I have a quote for a replacement.
I got to thinking about something yesterday. Even without power, if we had
a way for our laser printer(s) to work, we could have continued on our
merry way, though somewhat in the dark.
Laser printers should not/cannot be placed on a UPS due to power draw.
What about a portable generator? With the assurance that we have clean
power coming out of it. We wouldn't need EVERY laser printer running, just
one of them.
Anybody ever do this?
Thanks.
