How To Use This Manual
This is the manual for apcupsd, a daemon for communicating with UPSes
(Uninterruptible Power Supplies) made by American Power Corporation
(APC). If you have an APC-made UPS, whether sold under the APC name-
plate or OEMed (The HP PowerTrust 2997A UPS has been tested as a
“smartups” with cable Hewlett Packard part number 5061-2575 equivalent
to a custom-smart cable), and you want you get it working with a computer
running Linux, Unix, or Windows NT, you are reading the right document.
This manual is divided into parts which increase in technical depth as they
go. If you have just bought a state-of-the-art smart UPS with a USB or
Ethernet interface, and you are running a current version of Red Hat or
SUSE Linux (8.0 or later), then apcupsd is very nearly plug-and-play and
you will have to read only the Basic User’s Guide (see Basic User’s Guide).
If your operating system is older, or if you have an old-fashioned
serial-line UPS, you’ll have to read about serial installation (see
Installation on Serial-Line UPSes). If you need more details about adminis-
tration for unusual situations (such as a master/slave or multi-UPS setup)
you’ll need to read the section on advanced topics (see Advanced topics). Fi-
nally, there is a Technical Reference (see Technical Reference) section which
gives full details on things like configuration file directives and event-logging
formats.
You should begin by reading the Quick Start (see Quick Start for Beginners)
instructions.

The following is a help guide to the steps needed to get apcupsd set up and
running as painlessly as possible.
