When there's a dip in the mains voltage the UPS switches in and keeps things running. I have configured apcupsd to gracefully shut the machine down after a 5 second power outage. That APC UPS has been running for about 6 years now, still no problems with it. I get postcards from APC occasionally, asking if I'd like to trade in my UPS for a newer one. Not now thankyou ;) Kind Regards, Keith Roberts ----------------------------------------------------------------- Websites: http://www.php-debuggers.net http://www.karsites.net http://www.raised-from-the-dead.org.uk All email addresses are challenge-response protected with TMDA [http://tmda.net] -----------------------------------------------------------------
