2x UPS

2x UPS (Uninterruptable Power Supply) - PowerWalker VI 2200 RLE (Max effect 1300W) NOTE PICK-UP ONLY. Had them for about 3 years. Usually never have power outages so they have hardly been used other than voltage regulation. In the program PowerMaster120 for Windows you download from the internet & install on the servers, it has never warned that the batteries are bad & they have done battery self tests about once a week. Not sure if there is a program for Linux, so if you are using Linux you need to find out for yourself
