2-7  Jumper Settings
Explanation of Jumpers
To modify the operation of the motherboard, jumpers can be used to choose between optional settings. Jumpers create shorts between two pins to change the function of the connector. Pin 1 is identified with a square solder pad on the printed circuit board. See the motherboard layout pages for jumper locations.
Note: On two pin jumpers, "Closed" means the jumper is on and "Open" means the jumper is off the pins.
GLAN Enable/Disable
JPL1 enables or disables the GLAN Ports 1/2 on the motherboard. See the table on the right for jumper settings.
