Appendix A. Jumpers
Jumpers located on the system board and the processor board help
you to customize the way your server operates.
Changing Jumper Positions
Your system board and processor board contain two-pin and
three-pin jumper blocks.
In some cases, groups of two-pin jumpers combine to define a
function. For example, the settings of jumpers J1 and J20 together
define the clock speed of the microprocessor.
Two-Pin Jumper Blocks
Covering both pins with a jumper defines one function of the
jumper block. To change the function of the jumper block, cover
one pin only or remove the jumper entirely. To change a jumper's
position for a two-pin jumper block:
1. Turn off the server; then disconnect the server power cord.
2. Remove the server cover (see “Preparing to Add Options” on
page 126).
