Configuring the System Board
The system board contains a CMOS Clear configuration jumper, and two
sets of reserved jumper blocks (do not change).
The CMOS and Non-Volatile RAM (NVRAM) settings are only cleared if
the checksum test returns false. Access to specific setup fields is
controlled by a supervisor password or user password.
The Clear CMOS mode removes the password that is stored in CMOS. No
other parameters are cleared.

“Removing the Side Panel”
on page 22).
2
Set the jumpers as directed by a service technician (see
“Configuration Jumper”
on page 60).
3
Reinstall the side panel (see
“Replacing the Side Panel”
on page 25).
✍
The configuration jumpers should never need changing unless otherwise directed by a
technical support or service technician.

Before opening the system unit, save and close all open files, exit all open
applications, turn off the power to all attached peripheral devices, shut
