4. Reinstall the server cover and connect the cables (see "Completing the installation" on page 178). 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. 32 1 To change a jumper's position for a three-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 246). 3. Lift the jumper straight off the pin block. 4. Align the holes in the bottom of the jumper with the center pin and the pin that was not covered previously. 5. Slide the jumper fully onto these pins. 6. Reinstall the server cover and connect the cables (see "Completing the installation" on page 178). Netfinity 5500 M20 - Type 8662 177
