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. --Blake
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.
