Installing the 8233-E8B or 8236-E8C system processor assembly

Learn how to install the system processor assembly.

1. Perform the prerequisite tasks listed in Before you begin.
2. Stop the system or logical partition. See Stopping the system or logical partition.
3. Disconnect the power cables from the primary power supply and secondary power supply if present.
4. Open the front rack door.
5. Place the system in the service position. See Placing a rack-mounted 8233-E8B or 8236-E8C in the service position.
6. Remove the service access cover. See Removing the service access cover from a rack-mounted 8233-E8B or 8236-E8C.
   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 prior to 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.
7. Remove the system processor filler by lifting the filler out of the system.
8. Add memory or memory fillers to the new system processor assembly. Memory must be installed according to the memory module balancing table in Memory modules.
   Note: Adding memory to the system processor assembly maximizes the performance of the system processor. If additional memory was not ordered, move memory from the existing processor assembly, if possible.
9. Install the system processor assembly cover. If the system processor assembly cover is already installed, skip to step 11.
10. Perform the following steps to install the system processor assembly cover as shown in the following figure:
    1. Push the cover (A) down and slide it to the left under the flange (B).
    2. Tighten the screws (C).
    Figure 1. Installing the system processor assembly cover

    
11. Check for the protective cover that might be present on the lower-right connector pins. If a protective cover is present, remove the cover (A), as shown in Figure 2.
    CAUTION:
    Leaving the protective cover in place will prevent the installation of the processor and could damage the connector on the system backplane.
    Figure 2. Removing the protective cover from the connector pins

    
12. With the latches (A) in the unlocked position, place the system processor assembly (B) into the system as shown in Figure 3.
13. Move each latch (A) in the direction of the arrow to lock the system processor assembly into position.

14. Replace the service access cover. See Installing the service access cover on a rack-mounted 8233-E8B or 8236-E8C.
15. If you have a rack-mounted system, place it in the operating position. See Placing a rack-mounted 8233-E8B or 8236-E8C in the operating position.
16. Restore power to the system by reconnecting the system power cables.
17. Start the system or logical partition. See Starting the system or logical partition .
18. Verify that the system processor assembly is functional. See Verifying the installed part.
