As others have said, go with APC. I just recently hooked up a 2200XL rack mounted unit which is running 6 servers. A recent calibration test showed that the unit will run these servers for about 3 hours before it's absolutely necessary to shut down the power. Another nice thing about the APC's is that you can find SNMP/Web modules for some of their units which will generate SNMP traps when events occur with the power. I'm using apcupsd from the ports collection to control the servers in the event of a long term power outage. It has a configurable master/slave mode. You connect the master to the UPS and then slave from the master to other servers. My UPS and server are older so the connection between them is serial. You may get different results with newer hardware that is USB or if you choose to go the SNMP route. -- Chris -- __o "All I was doing was trying to get home from work." _`\<,_ -Rosa Parks ___(*)/_(*)___________________________________________________________ Christopher Sean Hilton pgp key: D0957A2D/f5 30 0a e1 55 76 9b 1f 47 0b 07 e9 75 0e 14
