3.6.2 Clear-CMOS Jumper
The location of the Clear-CMOS jumper (J110) on the Sun Fire V20z motherboard is
shown below. This jumper can be used to clear the CMOS if the server hangs during
certain conditions.
The default position for the jumper is pins 2+3, which is the setting for “Clear-
CMOS-Removed.” This setting retains CMOS settings on each reboot of the
server.
If you move the jumper to pins 1+2, this is the “Clear-CMOS-Installed” setting.
This setting will clear the CMOS settings with each reboot of the server.
