Using the Clear CMOS Header (J38, Pins 9 - 10)
You can use this header to clear the server's CMOS settings in the case of a system hang. For example, if the
server hangs because of incorrect settings and does not boot, use this jumper to invalidate the settings and
reboot with defaults.
Caution Clearing the CMOS removes any customized settings and might result in data loss. Make a note of any
necessary customized settings in the BIOS before you use this clear CMOS procedure.
