5-10 Jumper Settings
Explanation of Jumpers
To m o d i f y t h e o p e r a t i o n o f t h e
serverboard, jumpers can be used
to choose between optional settings.
Jumpers create shorts between two
pins to change the function of the con-
nector. Pin 1 is identifi ed with a square
solder pad on the printed circuit board.
See the serverboard 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 and JBT2 are 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). It is also recom-
mended that you remove the onboard battery from the serverboard.
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 onboard battery and power on the system.
Note: Do not use the PW_ON connector to clear CMOS.
