Protecting from power source problems

Protecting from power source problems
Line conditioners, and uninterruptible power supplies can help protect your server against
power source problems.
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 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. Be sure to use a UPS
with surge protection. To buy a UPS, contact Gateway Customer Care, Gateway Sales, or
visit accessories.gateway.com. For more information on contacting Customer Care, see
"Telephone support" on page 86.
