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 be- tween two pins to change the function of the connector. Pin 1 is identified with a square solder pad on the printed circuit board.
Note: On two pin jumpers, "Closed" means the jumper is on and "Open" means the jumper is off the pins.
LAN Port Enable/Disable
Use JPL1/JPL2 to enable or disable LAN Port 1 and LAN Port 2 on the motherboard. See the table on the right for jumper settings. The default setting is enabled.
