To help avoid damaging a computer with a manual voltage selection
switch, ensure that the voltage selection switch is set to match the AC
power available at your location:
– 115 V/60 Hz in most of North and South America and some Far
Eastern countries such as South Korea and Taiwan
– 100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan
NOTE: The voltage selection switch must be set to the 115-V position even
though the AC power available in Japan is 100 V.
– 230 V/50 Hz in some regions in the Caribbean and South America
and most of Europe, the Middle East, and the Far East
Also, ensure that your monitor and attached devices are electrically rated
to operate with the AC power available in your location.
• Before working inside the computer, unplug the computer to help prevent
electric shock or system board damage. Certain system board components
continue to receive power any time the computer is connected to AC
power.
• To avoid shorting out your computer when disconnecting a network
cable, first unplug the cable from the network adapter on the back of your
computer, and then from the network jack. When reconnecting a network
cable to your computer, first plug the cable into the network jack, and
then into the network adapter.
• To help avoid possible damage to the system board, wait 5 seconds after
turning off the computer before disconnecting a device from the
computer.
• To help prevent electric shock, plug the computer and device power
cables into properly grounded electrical outlets. These cables are
equipped with 3-prong plugs to help ensure proper grounding. Do not use
adapter plugs or remove the grounding prong from a cable. If you must
use an extension cable, use a 3-wire cable with properly grounded plugs.
