Main System Board Jumpers
The computer contains four blocks (groups) of jumpers: J3, J5,
J19, and J21. To access jumper blocks J19 and J21, you must
remove any option cards that are installed. You must remove
the drive housing to access jumper blocks J3 and J5.
See the previous page to locate the jumper blocks on your main
system board. Then follow the instructions below to change the
necessary jumper settings.
Caution
Do not install or remove any option cards when the drive
housing is removed from the computer. The housing
stabilizes the option card riser board and you could severely
damage it if you put stress on it without the support of the
drive housing. Also, do not change the settings in the
reserved jumper block J10; these jumpers must remain at
their factory settings.
