>&#13;An Uninterruptible Power Supply (UPS) is an important thing to have
if you live in an area where power outages are at all common,
especially if you run a mail/DNS/Web server that must be up 24/7. This
HOWTO will teach you things you need to know to select a UPS
intelligently and make it work with your open-source operating system.
