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.
