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 identifi ed 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/JPL2 enable or disable the GLAN
Port1/GLAN Port2 on the motherboard.
See the table on the right for jumper set-
tings. The default setting is enabled.
