Supermicro H8SCM-F User Manual: CMOS Clearing and Jumper Settings (JBT1 Solder Pad)

H8SCM(-F) SERVERBOARD USER'S MANUAL

2-9 Jumper Settings

Explanation of Jumpers

To modify the operation of the motherboard, jumpers can be used to choose between optional settings. Jumpers create shorts between two pins to change the function of the connector. Pin 1 is identiﬁed with a square solder pad on the printed circuit board. See the diagram at right for an example of jumping pins 1 and 2. Refer to the motherboard layout page for jumper locations.

CMOS Clear

JBT1 is used to clear CMOS, which will also clear any passwords. Instead of pins, this jumper consists of contact pads to prevent accidentally clearing the contents of CMOS.

To Clear CMOS

1.First power down the system and unplug the power cord(s). It is also recommended that you remove the onboard battery from the serverboard.

2.With the power disconnected, short the CMOS pads with a metal object such as a small screwdriver.

3.Remove the screwdriver (or shorting device).

4.Reconnect the power cord(s) and power on the system.

Note 1. For an ATX power supply, you must completely shut down the system, remove the AC power cord, and then short JBT1 to clear CMOS.

Note 2. Be sure to remove the onboard CMOS Battery before you short JBT1 to clear CMOS.

Note 3. Clearing CMOS will also clear all passwords.

Note 4: Do not use the PW_ON connector to clear CMOS.
