Protecting from power source
problems
During a power surge, the voltage of electricity coming into your computer
can increase to far above normal levels and cause data loss or system damage.
Protect your computer and peripherals by connecting them to a surge
suppressor, which will absorb voltage surges and prevent them from reaching
your computer.
During a power failure, an uninterruptable power supply (UPS) supplies battery
power to your computer. Although you cannot run your computer for an
extended period of time with a UPS, a UPS lets you run your computer long
enough to save your work and shut your computer down normally.
Warning When you shut down your computer the power turns off,
but some electrical current still flows through the computer.
To avoid possible injury from electrical shock, unplug the
power cable and modem cable from the wall outlets.
Warning High voltages can enter your computer through the phone
line connected to the modem. Protect your computer by
plugging the telephone line into a surge suppressor with
a modem connection. To further protect your computer
during an electrical storm, unplug both the surge
suppressor from the power outlet and the telephone line
from the phone jack.
