5-10 Jumper Settings

Explanation of Jumpers

To modify the operation of the mother- board, jumpers
can be used to choose between optional settings. Jump-
ers create shorts between two pins to change the func-
tion 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 a two-pin jumper, "Closed" means the jumper
is on both pins and "Open" means the jumper is either
on only one pin or completely removed.

CMOS Clear

JBT1 is used to clear CMOS (which will also clear any passwords). Instead of pins, this jumper consists of
contact pads to prevent accidentally clearing the contents of CMOS.
To clear CMOS,
1. First power down the system and unplug the power cord(s).

2. With the power disconnected, short the CMOS pads with a metal object such as a small screwdriver.

3. Remove the screwdriver (or shorting device).

4. Reconnect the power cord(s) and power on the system.

Note: Do not use the PW_ON connector to clear CMOS.

LAN1/2 Enable/Disable

Change the setting of jumper JPL1 and JPL2 to
enable or disable the LAN1 and LAN2 Ethernets
ports, re- spectively. See the table on the right for
jumper settings. The default setting is enabled.
