Power Protection Devices

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

• Surge protectors

• Line conditioners

• Uninterruptible power supplies (UPS)

16 Quick Reference Guide

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 and compare joule ratings to determine the

relative effectiveness of different devices. A device with a higher joule rating

offers more protection.

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).
