>1.1. Why this document?</H2
|
|
><P
|
|
>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. The
|
|
aging power grid in the U.S. has made this a more urgent issue than it
|
|
used to be even for American hackers, but everyone is vulnerable to
|
|
outages caused by storms and other natural phenomena. This document
|
|
covers both the software and hardware aspects of protecting
|
|
yourself.</P
|
|
><P
|
|
>The advice in this document is aimed primarily at small
|
|
installations — one computer and one UPS. Thus we'll focus on
|
|
consumer-grade UPSes, especially those designed for home and
|
|
small-business use. If you are a data center administrator running a
|
|
big server farm, there is a whole different (and much more expensive)
|
|
range of technologies we'll do no more than hint at here.</P
