Install model 55x, 720, 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. Take appropriate precautions for avoiding electric shock and handling static-sensitive devices. For information, see Avoiding electric shock and Handling static-sensitive devices.
2. 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.
3. Perform the prerequisite tasks described in Before you begin.
4. Stop the system or logical partition.
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 step 7.
   • If you are placing an adapter in a model 5790 or D11, use the PCI adapter cassette procedures. See Model 560Q, 570, 590, 595 , and attached expansion units, PCI adapters and cassettes.
   • Installing, removing, or replacing a PCI adapter in a D10, 5791, or 5794 expansion unit is not a customer procedure. Contact your service provider.
   • For the 55x 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 as follows:
        • 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:
        • 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.
11. 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 in this system, you must remove the blue handle or support bracket from the card.
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 55x, 720, or attached expansion-unit, PCI adapters and then return here.
    Figure 1. PCI adapter or filler plate removed from the rack-mounted system unit

    
    Figure 2. 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. Secure the adapter. Lower the tab onto the PCI adapter faceplate. Rotate the adapter locking latches clockwise as shown in Figure 3 or Figure 4.

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