Line conditioners
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 surge protectors and uninterruptible power supplies include simple
line-conditioning capabilities.
Uninterruptible power supplies
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. To buy a UPS, visit
