SUPER MICRO Computer X7DCL-3 Cmos Clear, Watch Dog Enable/Disable, Clear Cmos Watch Dog Enable

Chapter 2: Installation

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.
