Cmos Clear - Supermicro B1SD2-TF User Manual

CMOS Clear

P1- JBT1 (for Node 1) and P2-JBT1 (for Node 2) are used to clear the CMOS.
Instead of pins, this "jumper" consists of contact pads to prevent accidental clear-
ing 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 1: For an ATX power supply, you must completely shut down the
system, remove the AC power cord, and then short P1-JBT1/P2-JBT1 to
clear CMOS.
Note 2: Be sure to remove the onboard CMOS Battery before you short
P1-JBT1/P2-JBT1 to clear CMOS.
Note 3: Clearing CMOS will also clear all passwords.
