Power Protection Devices

Several devices are available to protect against power fluctuations and failures:

Surge protectors

Line conditioners

Uninterruptible power supplies (UPS)

Surge Protectors

Surge protectors and power strips equipped with surge protection help prevent damage to your computer
from voltage spikes that can occur during electrical storms or after power interruptions. Some surge
protector manufacturers include warranty coverage for certain types of damage. Carefully read the device
warranty when choosing a surge protector. A device with a higher joule rating offers more protection.
Compare joule ratings to determine the relative effectiveness of different devices.

NOTICE:

Most surge protectors do not protect against power fluctuations or power interruptions caused by

nearby lightning strikes. When lightning occurs in your area, disconnect the telephone line from the telephone wall
jack and disconnect your computer from the electrical outlet.

Many surge protectors have a telephone jack for modem protection. See the surge protector
documentation for modem connection instructions.

NOTICE:

Not all surge protectors offer network adapter protection. Disconnect the network cable from the

network wall jack during electrical storms.

Line Conditioners

NOTICE:

Line conditioners do not protect against power interruptions.

Line conditioners are designed to maintain AC voltage at a fairly constant level.

Uninterruptible Power Supplies

NOTICE:

Loss of power while data is being saved to the hard drive may result in data loss or file damage.

NOTE:

To ensure maximum battery operating time, connect only your computer to a UPS. Connect other devices,

such as a printer, to a separate power strip that provides surge protection.

A UPS protects against power fluctuations and interruptions. UPS devices contain a battery that
provides temporary power to connected devices when AC power is interrupted. The battery charges while
AC power is available. See the UPS manufacturer documentation for information on battery operating
time and to ensure that the device is approved by Underwriters Laboratories (UL).
