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.
Watch Dog Enable/Disable
JWD1 controls the Watch Dog function.
Watch Dog is a system monitor that
can reboot the system when a software
application hangs. The jumper on pins 1-2
(default) causes the Watch Dog to reset the
system if an application hangs. The jumper
on pins 2-3 generates a non-maskable
interrupt signal for the application that
hangs. See the table on the right for jumper
settings. Watch Dog must also be enabled
in BIOS. Note: When enabled, the user
must write their own application software
to disable the Watch Dog Timer.
BMC Enable/Disable
Use jumper JPB1 to enable or disable the
BMC (Baseboard Management Controller),
which supports IPMI 2.0/KVM. See the
table on the right for jumper settings.
Manufacturer Mode Select
Close jumper JPME1 to bypass SPI flash
security and force the system to operate
in Manufacturer Mode, which allows the
user to flash the system firmware from a
host server to modify system settings. See
the table on the right for jumper settings.
