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.
