Cmos Clear; Watch Dog - Supermicro X7DCL-3 User 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 clear-
ing 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 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.
