Using the Clear CMOS Jumper
You can use the Clear CMOS jumper to clear the server’s CMOS settings in the event
of a system hang. For example, if the server hangs because of incorrect settings and
will not boot, use this jumper to invalidate the settings and reboot with defaults.
1. Shut down the server to standby power mode by using a ballpoint pen or other
stylus to press and release the recessed Power button on the front panel.
See “Powering Off the Server” on page 14 .
2. Disconnect the AC or DC power cords from the server.
