SUPER MICRO Computer C2SBE Watch Dog Enable/Disable, Cmos Clear, Clear Cmos Watch Dog Enable

C2SBA+II/C2SBA+/C2SBA/C2SBE 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 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.)
