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 identifi ed with a square solder pad on the printed circuit board. See the serverboard layout pages for jumper locations.

Note: On two pin jumpers, "Closed" means the jumper is on and "Open" means the jumper is off the pins.

Setting

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.
