Jumper settings
Jumpers located on the I/O function card and processor controller board help you to customize the way the server operates.

The processor controller board and I/O function card contain two-pin jumper blocks and three-pin jumper blocks, respectively. In some cases, groups of jumpers might combine to define a function.

Attention: Before you begin, read Safety Information in the Hardware Maintenance Manual..

To change a jumper setting:

1. Remove the server top cover or front bezel, depending on the location of the jumper. See Preparing to install options .
2. Locate the jumper whose setting you want to change:
   • To change a two-pin jumper block, continue with Two-pin jumper blocks.
   • To change a three-pin jumper block, continue with Three-Pin jumper blocks .

Two-pin jumper blocks
Two-pin jumper blocks are located on the processor controller board. 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 the jumper setting on a two-pin jumper block:

1. Lift the jumper straight off the block; then, do one of the following procedures:
   
   
   • Align the holes in the bottom of the jumper with the two pins on the pin block, and then slide the jumper carefully onto these pins.
     
     

2. 

   • 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 carefully onto that pin only.
     
     

   

Reinstall the server top cover or front access cover and connect the cables. See Completing the installation.

Three-Pin jumper blocks

Three-pin jumper blocks are located on the I/O function card. 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 the three-pin jumper blocks that are described in this chapter:



To change the jumper setting on a three-pin jumper block:

1. Remove the I/O function card from the server:

a. Refer to the following illustration while you perform the steps in this procedure.



b. Disconnect all cables (1) from the I/O function card (2). Note carefully where each cable is connected before you remove it. See I/O function card component locations for the connector locations on the I/O function card.
c. Remove the two screws (4) located on the metal connector plate inside the server.
d. Remove the I/O function card retention bracket (3) on the right side of the card by pulling out the fastener on the bracket.
e. Carefully grasp the I/O function card by its top edge and pull the I/O function card out of the server.
f. Place the I/O function card connector-side up on a flat, static-protective surface.

2. Lift the jumper straight off the pin block.
3. Align the holes in the bottom of the jumper with the center pin and the pin that was not covered previously.



4. Slide the jumper fully onto these pins.
5. Reinstall the I/O function card by performing the following steps:

a. Refer to the illustration in step 1a while you perform the steps in this procedure.
b. Carefully grasp the I/O function card by its top edge, and insert the tabs on the bottom edge of the metal connector plate into the matching openings on the server back panel.
c. Align the I/O function card with the guide on the opposite end of the adapter and the slot on the I/O board.
d. Press the I/O function card firmly into the slot.

Attention : When you install the I/O function card in the server, be sure that it is completely and correctly seated. Incomplete insertion might cause damage to server components.

e. Reinstall the I/O function card retention bracket that you removed in step 1d by pressing in the fastener on the bracket.
f. Insert the two screws that you removed in step 1c.
g. Connect the cables that you disconnected in step 1b. See I/O function card component locations for the connector locations on the I/O function card.

6. Reinstall the server top cover or front access cover and connect the cables. See Completing the installation.
