Setting the Jumpers

If you need to change any jumper settings, follow these steps:

1.Refer to the illustration on page 3-5 to locate the jumpers.

2.If there are any option cards installed in your computer, you need to remove them to access the jumpers. See page 3-16.

3.A jumper’s setting is determined by where the jumper is placed on the pins. A two-pin jumper either connects both pins (on) or sits on just one of the pins (off). For three-pin jumpers, the jumper connects pin 1 and the middle pin (position 1-2) or pin 3 and the middle pin (position 2-3), as shown below.

To move a jumper from one position to the other, use needle-nose pliers or tweezers to pull it off its pins and gently move it to the desired position.

Caution

Be careful not to bend the jumper pins or damage any surrounding components on the main system board.

4.Replace any option cards you removed. See page 3-13 for instructions.
