Cmos Clear; Watch Dog Enable - Supermicro Supero C2SBX User Manual

C2SBX/C2SBX+ User's Manual

CMOS Clear

JBT1 is used to clear CMOS. Instead of pins, this "jumper" consists
of contact pads to prevent the accidental clearing of CMOS. To clear
CMOS, use a metal object such as a small screwdriver to touch both
pads at the same time to short the connection. Always remove the
AC power cord from the system before clearing CMOS.
Note: For an ATX power supply, you must completely shut down the system,
remove the AC power cord, and then short JBT1 to clear CMOS.
Watch Dog Enable/Disable
JWD controls the Watch Dog function. Watch
Dog is a system monitor that can reboot the
system when a software application hangs.
Close pins 1-2 to reset the system if an applica-
tion hangs. Close pins 2-3 to generate a non-
maskable interrupt signal for the application that
hangs. See the table on the right for jumper set-
tings. Watch Dog must also be enabled in the
BIOS. Note: When enabled, the user needs to
write his/her own application software to disable
the Watch Dog Timer.
