Protecting from power source problems

www.gateway.com

Lne conditioners and uninterruptible power supplies can help protect your 
server against power source problems.

A line conditioner protects your server from the small fluctuations in voltage 
from an electrical supply. Most servers can handle this variation, called line 
noise, without problems. However, some electrical sources include more line 
noise than normal. Line noise can also be a problem if your server is located 
near, or shares a circuit with, a device that causes electromagnetic interference, 
such as a television or a motor.

Some uninterruptible power supplies include simple line-conditioning 
capabilities.

Use an uninterruptible power supply (UPS) to protect your server from data loss 
during a total power failure. A UPS uses a battery to keep your server running 
temporarily during a power failure and lets you save your work and shut down 
your server. You cannot run your server for an extended period of time while 
using only the UPS. Be sure to use a UPS with surge protection. To buy a UPS,
