5-9 Jumper Settings
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 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 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
First power down the system and unplug the power cord(s). 1.
With the power disconnected, short the CMOS pads with a metal object such 2.
as a small screwdriver.
Remove the screwdriver (or shorting device). 3.
Reconnect the power cord(s) and power on the system. 4.
Note: Do not use the PW_ON connector to clear CMOS.

Watch Dog Enable/Disable
JWD1 enables the Watch Dog function, a
system monitor that takes action when a
software application freezes the system.
Jumping pins 1-2 will have Watch Dog reboot
the system if a program freezes. Jumping
pins 2-3 will generate a non-maskable
interrupt for the program that has frozen.
See the table on the right for jumper settings.
Watch Dog must also be enabled in BIOS.
Note : When Watch Dog is enabled, you
must write your own application software
to disable the Watch Dog Timer.
