Jumper Settings

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 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.
VGA Enable/Disable
JPG1 allows you to enable or disable the
VGA port. The default position is on pins
1 and 2 to enable VGA. See the table on
the right for jumper settings.
