Changing Jumper Positions - Netfinity 5600 - Type 8664
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:
- Turn off the server; then, disconnect the server power cords.
- Remove the server cover (see 'Preparing to install options').
- Do one of the following:
- Lift the jumper straight off the pin block.
- 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.
- 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.
- Reinstall the server cover and connect the cables (see 'Completing the installation').
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.
To change a jumper's position for a three-pin jumper block:
- Turn off the server; then, disconnect the server power cords.
- Remove the server cover (see 'Preparing to install options').
- Lift the jumper straight off the pin block.
- Align the holes in the bottom of the jumper with the center pin and the pin that was not covered previously.
- Slide the jumper fully onto these pins.
- Reinstall the server cover and connect the cables (see 'Completing the installation').
