1.8.7 Clear CMOS Header: CLR_CMOS
There is a CMOS RAM onboard that has the power supplied from an external battery to
maintain the registry settings of system configuration.
For normal state (default), the jumper is set on pin location 2 and 3.
To clear the CMOS, here is the procedure:
1. Disconnect all power connections to ECM-3455J first,
2. Set the “CLR_CMOS” jumper to pin location 1 and 2 for at least 30 seconds while the
system is disconnected from the power.
3. Place the jumper back to pin location 2 and 3 for mainboard normal operation.
1.
Avoid clearing the CMOS while the system is ON, which may damage the
mainboard.
