Setting Up Your Computer

CAUTION: Before performing any of the procedures in this section, follow the safety instructions in

Product Information Guide.

NOTICE: If your computer has an expansion card installed (such as a modem card), connect the

appropriate cable to the card, not to the connector on the back panel.

You must complete all the steps to properly set up your computer. See the appropriate figures that

follow the instructions.

1

Connect the keyboard and mouse.

NOTICE: Do not attempt to operate a PS/2 mouse and a USB mouse simultaneously.

2

Connect the modem or network cable.

Insert the network cable, not the telephone line, into the network connector. If you have an

optional modem, connect the telephone line to the modem.

NOTICE: Do not connect a modem cable to the network adapter. Voltage from telephone

communications can cause damage to the network adapter.

NOTE: Some monitors have the video connector underneath the back of the screen. See the

documentation that came with your monitor for its connector locations.

4

Connect the speakers.

5

Connect power cables to the computer, monitor, and devices and insert the other ends of the

power cables to electrical outlets.

Verify that the voltage selection switch is set correctly for your location.

Your computer has a manual voltage selection switch. Computers with a voltage selection

switch on the back panel must be manually set to operate at the correct operating voltage.

NOTICE: To help avoid damaging a computer with a manual voltage selection switch, set the switch for

the voltage that most closely matches the AC power available in your location.

NOTE: Before you install any devices or software that did not ship with your computer, read the

documentation that came with the device or software, or contact the vendor to verify that the device or

software is compatible with your computer and operating system.

NOTE: Your computer may vary slightly from the following setup figures.
