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.
