Explanation of Jumpers
To modify the operation of the server 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. Refer to the server board 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.
