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.
1
Remove the side cover (see “Removing the Side Cover” on page 22).
2
Set the jumpers as directed by a service technician (also see
“Configuration Jumpers” on page 63).
3
Reinstall the side cover (see “Replacing the Side Cover” on page 23).
✍
The configuration jumpers should never need changing unless otherwise directed by a
technical support or service technician.
