Yesterday Howard asked: <<We recently purchased an APC Matrix MX5000XR UPS to handle the new servers we have installed here and I'm wondering if anyone has had any experience hooking a 3000 to one of these guys. >> We have been running our Series 959KS/200 on APC Matrix UPS for over two years; first a 5 KVA and right now a 3 KVA. No UPS problems. With only the SPU, four internal 2-GB discs, ten external 4-GB discs, five external 2-GB discs, two DDS drives, and the console, believe it draws 42 percent of rated load for the 3 KVA Matrix UPS... oops.... guess we've got one PC plugged in to the 3 KVA too. If you don't have separate overtemp / high humidity cutouts upstream of your Matrix UPS, note that there are relatively inexpensive plug in options for the later models that will do that. Also note that the APC Matrix does *not* provide a plug-compatible equivalent to the HP UPS system shutdown signal (or system crash signal, I believe is more accurate). So you have to do at least some roll-your-own in this area to maintain that feature. See APC on the web for all their info.... But you've probably already paid them a visit, at: http://www.apcc.com/ Ken Sletten
