Changing Jumper Positions
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 the pin to the rear or to the front of the
center pin (as you face the front of the server). To change a
jumper's position for a three-pin jumper block:
1. Turn off the server; then disconnect the server power cord.
2. Remove the server cover.
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 reconnect the cables (see
“Completing the Installation” on page 111 for instructions).
