I once blew out an APC by miswiring a switch on a computer (don't ask). I called tech support, they agreed that what I told them had happened shouldn't have happened, and shipped me a new UPS for free, without any hassle. From that point on, I swore I'd go APC first. > Do any of > these power supplies come with scripts to shutdown a Unix {or > Linux} computer? Not that I know of...there's daemons you can install for that purpose, though. >Is there a UPS that is designed for heavy use > and a very short (5- to 10-second) uptime? Generally you need to add up your power requirements and match the load to the UPS's power rating. >I'll need one that can > interface thru the COM ports or the UBS port, if that is how > these devices work. Today it's common to have a USB interface.
