        • 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
4. If you are removing or replacing 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
5. Determine which adapter you plan to remove.
6. Adapter slots are numbered on the rear of the system unit, record the slot number and location of each adapter being removed.

11. At the Task Selection list, select PCI Hot Plug Manager.
12. Select Unconfigure a Device, then press Enter.
13. Press F4 (or Esc +4) to display the Device Names menu.
14. Select the adapter you are removing in the Device Names menu.
15. In the Keep Definition field, use the Tab key to answer Yes. In the Unconfigure Child Devices field, use the Tab key again to answer YES, then press Enter.
16. The ARE YOU SURE screen displays. Press Enter to verify the information. Successful unconfiguration is indicated by the OK message displayed next to the Command field at the top of the screen.

21. Press Enter. This places the adapter in the action state, meaning it is ready to be removed from the system.
22. Label, and then disconnect all cables attached to the adapter you plan to remove.
23. Remove the adapter. If you are removing a short adapter, continue to the next step.

    If you are removing a long adapter, unlatch and open the PCI adapter light-pipe plate C attached to the fan tray as shown in figure Figure 1 or Figure 2.

24. Rotate the adapter locking latch A counterclockwise.
25. Lift the black tab B attached to the adapter retainer assembly, and keep the black tab in a vertical position.
26. Carefully grasp the PCI adapter by its top edge or upper corners, and remove it from the system. Store the adapter in a safe place.

       Note: The light pipes below the light-pipe plate must fit through the holes in the plate for it to latch correctly.
    2. Note the guide grooves located toward the front of the system in the disk drive backplane, and align the adapter properly.
31. 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.
