Jumper Settings

Explanation of Jumpers

To modify the operation of the mother-
board, 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.
Note: On two-pin jumpers,
"Closed" means the jumper is on,
and "Open" means the jumper is
off the pins.

LAN Ports Enable/Disable

Jumper JPL1 enables or disables Ethernet
LAN ports on the motherboard. See the
table on the right for jumper settings. The
default setting is enabled.
