UPS issues with PFC PSU
 
Just noticed that our new server has a newer 80+ efficiency 865W PSU
with PFC. So apparenty our existing 1500VA (865W) APC Back-UPS is not
safe to use anymore. We apparently need a pure sine wave UPS.

http://nam-en.apc.com/app/answers/detail/a_id/8883

I found an affordable 1500VA UPS by CyberPower, model CP1500PFCLCD,
which has a pure sine wave output.
Wondering if anyone has experience with CyberPower UPS's. Are they any
good? Any problems with pwrstatd ?

oooooooffff-toooooooppppppppiiiiiiiicccccc. And this one belongs in the
second category. Really, please take this elsewhere. Thanks.

I've seen many threads about hardware recommendations as there are
many sys admins on this list. It IS for a CentOS box if that makes it
more on topic. Maybe I should have put an 'OT' in front of the
subject.

Anyway, have you anything experience with CyberPower UPS's?

Thanks

Please don't argue. Just don't send any more way off-topic stuff in the
future. Thanks.

Have you found a program to communicate with it for getting it's/line's
status, and causing shutdown to occur gracefully? And what program was
it? :)
That was the issue I had with one a few years ago.

Please don't top-post.

Because the original post made no mention of "CentOS" at all. At least
that's my guess and that's also the first impression I had about the
post.

> please stop being so stuckup

Please understand that this list has been filled with off-topic garbage
over the past year or so and many of us are getting more than a little
frustrated with it. Many people that have been here for years have
unsub'd and many more continue to mention that as a possibility. Add to
that the fact that some of the centos team themselves are no longer on
this list and that should tell you something. While this thread turned
out to have a centos connection the same can not be said for many of the
others over the past year.

well, where else would he connect the UPS to? His fish tank?
Surely if someone has a PC, and is subscribed to a Linux mailing linux
and asks for advice on a hardware device then it would be related to
compatibility as well.

Someone running Windows probably wouldn't even know if there are other
brands available than what he can get from his local PC shop. And just
about every single piece of hardware, which can be purchased from any
shop will always work on Windows. So why would he bother asking if it
would work?

EVEN if that's the case (staff leaving and people getting irretated),
it's still no reason to be rude with someone without knowing all the
facts to his question first.

Many people would rather trust the advice given on a list like this
than the advice given by a sales rep. Just cause you're a genius and
don't need any help with anything ever, doesn't mean the next guy is
as clever as you.
