System board jumper blocks

Any jumper blocks on the system board that are not shown in the illustration are reserved. For normal operation of the system, no jumpers should be installed on any of the jumper blocks. See “Recovering BIOS” on page 18 for information about the Flash ROM page-swap jumper.

System board switch block

The switch block contains microswitches 1-8. As pictured in this illustration, switch 1 is at the top of the switch block and switch 8 is at the bottom. For more information about this switch block see “Setting the password override switch” on page 34.
