Configuring Your System

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.

Remove the cover (see “Removing the Cover” on page 22).

Set the jumpers as directed by a service technician (also see

“Configuration Jumpers” on page 67).

Reinstall the cover (see “Replacing the Cover” on page 26).

Reinstall the front panel (see “Replacing the Front 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, save any open files, exit the Microsoft

Windows

operating system, turn off the power of the computer and all

attached peripherals, and unplug the power cord.
