Clearing the CMOS RAM
You may need to clear the Setup configuration values stored in the
CMOS RAM if the configuration has been corrupted, or if incorrect
settings made in the Setup utility have caused error messages to be
unreadable. Clearing the CMOS RAM removes the administrator
password.
Clearing the CMOS RAM can be done either by using the CMOS clear
jumper, or by removing the CMOS battery. Go to page 47 for
instructions on how to remove the battery.
To clear the CMOS RAM using the mainboard jumper:
1 Perform the pre-installation instructions described on page 26.
2 Remove the side panel from the chassis following the instructions
on page 27.
3 Locate the Clear CMOS jumper on the mainboard.
If necessary, remove any cables that prevent access to the jumper.
4 Move the jumper from the default position (at pins 1 and 2) to the
Clear CMOS position, covering pins 2 and 3.
5 Reconnect the AC power and turn on the server.
6 When the server begins to emit beeping sounds, power it down
and disconnect the AC power.
7 Move the Clear CMOS jumper back to its default position.
8 Observe the post-installation instructions described on page 26.
