Cmos Clear; Watch Dog - Supermicro X7DVL-L User Manual

X7DVL-L 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
Watch Dog (JWD) is a system monitor that can
reboot the system when a software application
hangs. Close pins 1-2 to reset the system if an
application 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
settings. Watch Dog must also be enabled in the
BIOS.
