2x UPS PowerWalker VI 2200 RLE

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. The batteries should be ok. 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. Comes with 2 data cables for communication between UPS & server. If you have multiple servers, you can make them less important servers for Clients, while the server in which the data cable is connected & has direct communication to the UPS, is an Agent. The client servers must then be connected to the Agent server via internet cables. You can choose that in the event of a power failure, all servers shut down for about 5 to 15 minutes, before the battery runs out. But UPSs can also be good for automatically regulating the voltage so that the server power supply, etc. gets less of a beating.
