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.

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