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.

instructions.
