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 cover (see “Removing the Cover” on page 22).
2 Set the jumpers as directed by a service technician (also see
“Configuration Jumper” on page 70).
3 Reinstall the cover (see “Replacing the Cover” on page 26).
4 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.
