Install model 285, 515, 52x, or attached expansion-unit, PCI adapters with the system power off

You might need to install a PCI adapter. Use the procedure in this section to perform this task.

1. Determine in which slot to place the PCI adapter by doing the following:
   • Refer to PCI adapter placement in the system unit or expansion unit for information regarding slot restrictions for adapters used in this system.
   • Determine if the adapter will be placed in the base system unit or an expansion unit.
     • If the adapter is to be placed into the base system unit, continue with this procedure by going to the next numbered step.
     • If the adapter is to be placed into an expansion unit that does not contain PCI adapter cassettes, continue with this procedure by going to the next numbered step.
     • If the adapter is to be placed into an expansion unit that contains PCI adapter cassettes, go to the procedures for adapters in adapter cassettes. See Model 560Q, 570, 590, 595 , and attached expansion units, PCI adapters and cassettes.
2. Perform the prerequisite tasks described in Before you begin.
3. Stop the system or logical partition.
4. Take appropriate precautions for avoiding electric shock and handling static-sensitive devices. For information, see Avoiding electric shock and Handling static-sensitive devices.
5. Disconnect the power source from the system by unplugging the system.
   Note: This system might be equipped with a second power supply. Before continuing with this procedure, ensure that the power source to the system has been completely disconnected.
6. If you are installing a PCI adapter in a rack-mounted system or expansion unit, follow these steps. If you are servicing a stand-alone system, go to the next step.
   • For the 52x system unit, the 0595, 5095, or D20 expansion unit, follow these steps:
     1. Open the front rack door.
     2. Place the system or expansion unit in the service position. See Place the rack-mounted system or expansion unit in the service position.
     3. Remove or open the service access cover using one of the following methods:
        • Remove the service access cover from the model 285, 51x, 52x, 55x, 710, or OpenPower 720.
        • Open the model 0595, 5095, or D20 service access cover.
   • For all other rack-mounted expansion units, follow these steps:
     1. Open the back rack door.
     2. Remove the cover or covers. For instructions on removing covers, select the appropriate procedure from the following list:
        • Remove the back door from the 5074, 5079, and 5094 expansion unit. These steps also apply to the 5294, 8294, and 9194 expansion units. When the cover is removed, remove the PCI adapter access plate.
        • Remove the back cover from the 0588 expansion unit. These steps also apply to the model 5088.
        • Open the model 0595, 5095, or D20 service access cover.
7. If you are installing a PCI adapter in a stand-alone system or expansion unit, follow these steps:
   • Remove the service access cover from the model 285, 51x, 52x, 55x, 710, or OpenPower 720.
   • Remove the back door and cover from the 5095 expansion unit.
8. If necessary, remove the adapter expansion slot shield.
9. If necessary, remove the adapter from the antistatic package.
   Attention: Avoid touching the components and gold-edge connectors on the adapter.
10. Place the adapter, component-side up, on a flat, antistatic surface.
    Note: Some PCI adapter cards are shipped from the manufacturer with a blue handle or support bracket along the back edge of the card. To use adapters of this type, remove the blue handle or support bracket from the adapter.
11. If you are installing a short adapter, continue to the next step. If you are installing a long adapter, do the following:
    1. Unlatch and open the PCI adapter light-pipe plate C that is attached to the fan tray as shown in figure Figure 1 or Figure 2.
    2. Note the guide grooves located toward the front of the system in the disk drive backplane when aligning the adapter.
12. Rotate the adapter locking latch A counterclockwise as shown in Figure 1 or Figure 2.
13. Lift the black tab B attached to the adapter retainer assembly, and keep the black tab in a vertical position.
14. Ensure the slot is empty. Remove the adapter filler plate if one is present. If an adapter is present in the slot you want to use, see the instructions in Remove model 285, 515, 52x, or attached expansion-unit, PCI adapters, and then return here.

    Figure 2. Model 52x PCI adapter or filler plate removed from the stand-alone system unit

    
15. Carefully grasp the adapter by its top edge, and align the adapter with the expansion slot and its connector on the system backplane.
16. Press the adapter firmly into its connector.
17. If you are installing a short adapter, continue to the next step. If you are installing a long adapter, do the following:
    Close and latch the PCI adapter light-pipe plate C attached to the fan tray as shown in figure Figure 3 or Figure 4.

    Note: The light pipes below the light-pipe plate must fit through the holes in the plate for it to latch correctly.
18. Secure the adapter. Lower the tab A onto the PCI adapter faceplate as shown in figure Figure 3 or Figure 4. Rotate the adapter locking latch B clockwise until it covers the tab at approximately a 45-degree angle.

19. Connect any adapter cables.
20. If you are servicing a rack-mounted system, route the cables through the cable-management arm.
21. Replace or close the covers.
22. On a rack-mounted system, close the rear rack door.
23. Place the rack-mounted system or expansion unit in the operating position if you are servicing a rack-mounted system. If you are servicing a stand-alone system, continue to the next step.
24. Reconnect the power source to the system.
25. Start the system or logical partition.
26. Verify that the new resource is functional. Refer to Verify the installed part.
