Installing the 8204-E8A or 9409-M50 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. For instructions, see Stopping the system or logical partition.
3. Disconnect the power cables from the primary power supply and secondary power supply if present.
4. If you have a rack-mounted system, open the front rack door.
5. If you have a rack-mounted system, place it in the service position. For instructions, see Placing a rack-mounted model 8203-E4A, 8204-E8A, 9407-M15, 9408-M25, or 9409-M50 in the service position.
6. Remove the service access cover. For instructions, see Removing the service access cover from a rack-mounted model 8203-E4A, 8204-E8A, 9407-M15, 9408-M25, or 9409-M50 or Removing the service access cover from a stand-alone model 8203-E4A, 8204-E8A, 9407-M15, 9408-M25, or 9409-M50.
   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 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.
   Restriction: If additional memory was not ordered, you must move memory from the processor. Each system processor assembly must have at least one pair of memory modules. See the memory module balancing table in the Memory modules topic collection to verify that the memory modules are balanced correctly.
9. Install the system processor assembly cover. Use the instructions for the figure that matches your cover to install the cover on the system processor.
   • If you have the flat cover shown in Figure 1, install the cover (B) under the sheet metal flange (C) and tighten the two screws (A).
     Figure 1. Installing the flat system processor assembly cover

     
   • If you have the cover shown in Figure 2, install the cover under the flanges on each side of the processor assembly. To install the cover, push the cover (A) down and slide it to the left under the flanges (B) and (C).

10. With the latches (A) in the unlocked position, place the system processor assembly (B) into the system as shown in Figure 3 and Figure 4.
11. Move the latch (A) in the direction of the arrow to lock the system processor assembly into position.

12. Replace the service access cover. For instructions, see Installing the service access cover on a rack-mounted model 8203-E4A, 8204-E8A, 9407-M15, 9408-M25, or 9409-M50 or Installing the service access cover on a stand-alone model 8203-E4A, 8204-E8A, 9407-M15, 9408-M25, or 9409-M50.
13. If you have a rack-mounted system, place it in the operating position. For instructions, see Placing a rack-mounted model 8203-E4A, 8204-E8A, 9407-M15, 9408-M25, or 9409-M50 in the operating position.
14. The server now requires 220 V ac input power to operate. If new power cables were part of this order, replace the existing power cables.
15. Restore power to the system by reconnecting the system power cables.
16. Start the system or logical partition. For instructions, see Stopping the system or logical partition .
17. Verify that the system processor assembly is functional. For instructions, see Verifying the installed part.
