Changing jumper positions

Jumpers located on the system board help you to customize the way your server
operates.
Your server system board contains three-pin jumper blocks.
In some cases, groups of jumpers might combine to define a function.
Three-pin jumper blocks
With the three-pin jumper blocks, each jumper covers two of the three pins on a pin
block. You can position the jumper to fit over the center pin and either of the other
two pins.
The following illustration identifies pins 1, 2, and 3 on a three-pin jumper block.
