Changing jumper positions
Jumpers located on the system board and the processor
board help you to customize the way the server operates.
The system board and processor board contain two-pin
and three-pin jumper blocks.
In some cases, groups of jumpers might combine to define
a function.
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.
The following illustration identifies pins 1 and 2 on a
two-pin jumper block.

To change a jumper's position for a two-pin jumper
block:
1. Turn off the server; then, disconnect the server power
cords.
2. Remove the server cover (see “Preparing to install
options” on page 100).
3. Do one of the following:
Ÿ
Lift the jumper straight off the pin block.
Ÿ
Align the holes in the bottom of the jumper with
the two pins on the pin block, and then slide the
jumper onto these pins.
Ÿ
Align one of the holes in the bottom of the
jumper with one of the pins on the pin block, and
then slide the jumper onto that pin only.
