Explanation of Jumpers
To modify the operation of the
serverboard, 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. See the diagram at right
for an example of jumping pins 1 and
2. Refer to the serverboard layout
page for jumper locations.
Note: On two-pin jumpers, "Closed"
means the jumper is on and "Open"
means the jumper is off the pins.
CMOS Clear
JBT1 is used to clear CMOS and 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.
