Removing an expansion riser from the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C, or 8205-E6D with the power off

You can remove the optional expansion riser that provides four more PCI adapter slots to your system.

1. Complete the prerequisite tasks that are described in Before you begin.
2. Take appropriate precautions for avoiding electric shock and handling static-sensitive devices. For information, see Avoiding electric shock and Handling static-sensitive devices.
3. Stop the system or logical partition. For instructions, see Stopping a system or logical partition.
4. If your system is a rack-mounted system, place the system into the service position. For instructions, see Placing a rack-mounted model into the service position.
5. Remove the service access cover.
   • For a rack-mounted system, see Removing the service access cover on a rack-mounted system.
   • For a stand-alone system, see Removing the service access cover on a stand-alone system.
6. Reach behind the system and disconnect all power cords from the unit you are servicing.
   Figure 1. Disconnecting the power cords
   Note: An optional power supply is available in the 8202-E4B, 8202-E4C, or 8202-E4D system. The 8205-E6B, 8205-E6C, or 8205-E6D system is equipped with a mandatory second power supply. Before continuing with this procedure, ensure that the power source to the system has been disconnected.

7. Attach the wrist strap.
   Attention:

   • Attach a wrist strap to an unpainted metal surface of your hardware to prevent electrostatic discharge (ESD) from damaging your hardware.
   • When using a wrist strap, follow all electrical safety procedures. A wrist strap is for static control. It does not increase or decrease your risk of receiving electric shock when using or working on electrical equipment.
   • If you do not have a wrist strap, just before removing the product from ESD packaging and installing or replacing hardware, touch an unpainted metal surface of the system for a minimum of 5 seconds.
8. Remove any PCI adapters that are seated in the expansion riser. For instructions, see Removing a PCI adapter from the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C, or 8205-E6D with the power off.
9. Loosen the securing knobs (A) on the expansion riser by turning them counterclockwise.

10. Pinch the expansion riser latch (B) and lift the latch into the open position.
11. Pull the latch mechanism up to unlock the expansion riser.
12. Carefully lift the expansion riser out of the system.
13. If you are removing an expansion riser as part of another procedure, return to that procedure. If not, continue to the next step.
14. If you plan to install another expansion riser into the vacated slot, go to Replacing an expansion riser in the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C, or 8205-E6D with the power off; otherwise, continue with the next step.
15. If you do not plan to install another expansion riser into the vacated slot, insert the metal PCI filler in slot C1. A PCI filler must be in every PCI slot that does not have an adapter installed.
16. If you do not plan to install another expansion riser into the vacated slot, insert a black plastic air baffle as shown in Figure 3.

17. Replace or close the service access cover.
    • For a rack-mounted system, see Installing the service access cover on a rack-mounted system.
    • For a stand-alone system, see Installing the service access cover on a stand-alone system.
18. For a rack-mounted system, place the system into the operating position. For instructions, see Placing a rack-mounted model into the operating position.
19. Reconnect the power source to the system.
20. Start the system or logical partition. For instructions, see Starting a system or logical partition.
