Protecting against power source
problems
Surge suppressors, line conditioners, and uninterruptible power supplies (UPS)
can help protect your system against power source problems.
Surge suppressors
During a power surge, the voltage level of electricity coming into your system
can increase far above normal for a few milliseconds. Data may be lost or the
system may be damaged. To protect against power surges, use a surge
suppressor. The surge suppressor absorbs voltage surges and prevents them
from reaching your system.
You plug a surge suppressor into an electrical outlet, then you connect your
computer, monitor, and other devices to it instead of directly to the outlet.
If you have a modem, make sure your surge suppressor has jacks for the
telephone and modem cables. Power surges can pass through telephone wires
as well as electrical wires.
