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 to prevent damage to
your computer from voltage spikes that can occur during electrical storms or following power
interruptions. The level of protection is usually commensurate with the cost of the surge
protector. 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.
