Safety Instructions
Use the following safety guidelines to help protect your computer system from
potential damage and to ensure your own personal safety.
When Using Your Computer System
As you use your computer system, observe the following safety guidelines.
CAUTION: Do not operate your computer system with any cover(s) (includ-
ing computer covers, bezels, filler brackets, front-panel inserts, and so on)
removed.
•
To help avoid damaging your computer, be sure the voltage selection switch on
the power supply is set to match the AC power available at your location:
— 115V for most of the Americas, Japan, South Korea, and Taiwan
NOTE: The AC power available in Japan is 100 volts (V), but the voltage
selection switch must be set to the 115V position.
— 230V for most of Europe, the Middle East, and the Far East
Also be sure that your monitor and attached peripherals are electrically rated to
operate with the AC power available in your location.
•
Before working inside the computer, unplug the system 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.
•
Verify that the system board’s standby light-emitting diode (LED) is not on. If it is
on, you may need to wait 10 to 30 seconds for it to go out.
