I have a couple of small machines (home PBX) and run a (tiny) USB APC UPS (nice set of TLA's!)...and love it. Serial ports are so 90's! :-> I am running: Debian Linux X100P FXO card ...and apcupsd: http://www2.apcupsd.com/ (on debian "apt-get install apcupsd")
I like it because it can slave 1 (in my case) or more machines to the apcupsd...so they all gracefully shut down when the UPS is on it's last leg...and power back up (via BIOS settings) when power returns. I have it (apcupsd) setup to email my cell phone when it goes on battery, shuts down or power returns...cute. I looked into this daemon because friends of mine who work under SLA's with big machines and BIG APC UPS's use it and are happy...can't beat that with a stick.
I hope that helps, Todd

Can someone recommend a good UPS for using with an * machine that provides some linux tested software to do managed shutdown in case of power loss?
