CyberPower UPS
This document describes how to install the CyberPower UPS daemon PowerPanel or alternatively the Network-UPS-Tools. The main advantage of using a CyberPower UPS is that it is cheap and it can communicate with your Linux box through either a RS-232 or USB serial connection. In the event of a prolonged power outage, should the CyberPower UPS lose most of its battery capacity, it can tell the Linux box to perform a safe shutdown.

Using Network UPS Tools
If you do not wish to use PowerPanel, the Network UPS Tools (NUT) is an alternative. Only one of these programs (PowerPanel or NUT) is required to monitor and shut the system down. You shouldn't use both as they might interfere with one another.
Use instructions from the Wiki page of Network UPS Tools.
