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.

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 ?
Sorry to be mean. But there are things off-topic and there are things 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

Small ones, for workstations? Yep, I've got one on mine at home. Been good.
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 argue. Just don't send any more way off-topic stuff in the future. Thanks.

How exactly is it OT if he needs the UPS to talk to CentOS??????

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 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.

Sorry I should have initially stated it was for CentOS6.

Thanks for the support but I really don't want my query to turn into a debate about what's off topic. It's just that I have only ever used APC and apcupsd. I've never used CyberPower and wondered if other CentOS people were using it with success/reliability. If that's off topic then I've learned something.

cypberpower does provide a linux utility to communicate with their ups systems. I have one that is on three server...:)

nut (Network UPS Tools) also works fine with Cyberpower UPSs via USB. Use the generic usbhid-ups driver. The nut package is available from the EPEL repo (nut-2.2.2-1.el5, nut-2.4.3-4.el6).

Based on past nonsensical threads in this list that is indeed a possibility, yes.

Sorry, I don't make such assumptions; quite frankly neither should you or anyone else.

Does it make you feel better to insult the many, many millions of people that run windows?

I suppose it's too much to ask that people make a connection to CentOS in their initial post so all these types of arguments can be put to rest? It not only makes the post valid but it also supplies the readers of the list with the additional information they need to actually help the original poster. Note: I am simply using the OP of this thread as an example, I am not necessarily pointing fingers.

Lately the advice on this list is quite often of questionable worth.

Come on John, you know HDDs do not work in water-filled fish tanks.

And this type of completely off-topic crap is exactly what I was referring to.
If people would engage that thing that $deity gave them at birth called a "brain" before running their mouth, or in this case their fingers, this list wouldn't be nearly as polluted as it's become over the past few months.
Additional lists aren't required; common sense, however, is.

I think many Linux users feel genuinely sorry for those who know only Windoze especially with their viruses, Trojans, Blue-Screen-of-Death and other worrying experiences including 'my computer is very, very slow - what can I do?'

We have used several CyberPower sine-wave, AVR UPS units in our server room - AVR1500, I believe. The cyber power monitoring app that comes with the UPS (also available on the site) works fine in Redhat Linux, though we don't use it, and I have not tested it in a few years (last version was probably RH5).
However, we have not found them to be 100% reliable. We use them with a mix of equipment from different vendors. While the units work fine when tested, in production they sometimes do not switch fast/early enough and we have experienced several equipment reboots due to this. We have tightened the thresholds in the CyberPower control software so that the UPS will kick in more frequently, but the adjustments are pretty limited. Because of this, we have moved the units to non-critical equipment or equipment that is protected by a redundant power source through an APC UPS. We've since stopped buying the units for server use, but may consider them for desktop use.

I haven't used CyberPower UPS's in the office (currently all variations of the APC Smart-UPS), however, I do have three basic CyberPower's at home. One for my computer and the networking equipment, one for my wife's computer, and one for the DVR and other electronics. I have been using them for a few years now and have yet to have a problem.
