Setting the Jumpers

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

1.Refer to the illustration on page 4-3 to locate the jumpers,

2.If there are any option cards installed, and you want to change the setting for jumper J3, you may need to remove the cards. See page 4-19.

3.A jumper’s setting is determined by where the jumper is placed on the pins. For three pin jumpers, the jumper connects pin 1 and the middle pin (position A) or pin 3 and the middle pin (position B), 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.
