i run my boxes 24/7/365. only time that i shut down is when i go out of town for more than 3 days, tho i did leave them up while i was out for a week. when i returned, all was well, we did have a small el storm, but logs showed no shutdown. as a suggestion, put sasd suppressor at mains electrical panel. this will protect _all_ electrical afer panel. you could put all of you cpu boxes on 1 ups, but i would suggest using at least 2. put main file server and main workstation boxes on 1 ups, secondary boxes on 2nd. this is how i am set up, main ups is an apc smart-ups 600, loaded with main file server, workstation, firewall, lan concentrator, kvm switch. secondary is an apc network power cell 600, loaded with second file server, scsi server, 1 printer. to determine power requirements, check labels on back of equipment for voltage and amps ratings. multiply volts x amps = va load to determine require ups. you can still use your seperate ac line feeds, but will only need 2 if you run 2 boxes per ups. as a bit of additional info, this came yesterday from apc... +++ 3) Don't get Zapped...APC Protects Your Electronics from Lightning Strikes! Lightning is a force of nature that both fascinates and frightens us. Lightning has come to symbolize power. It has also come to symbolize danger, with good reason! Scientists have estimated that at any given moment there are nearly 2,000 thunderstorms occurring over the earth's surface. That means about 100,000 thunderstorms annually for the U.S. This summer, make sure APC products protect all of your valuable electronics!
