4.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), as illustrated below.

ONO F F

For three pm jumpers, the jumper connects pin 1 and the middle pin (position l-2) or pin 3 and the middle pin (position 2-3), as shown below.

(In the off position, a three pin jumper sits on only one of the end pins.)

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.
