Install model 9116-561 or 570 memory modules

You might need to install memory modules in the server. Use the procedure in this section to perform this task.

If your system is managed by the Hardware Management Console (HMC), see Table 1 for the order in which you place the memory modules, and then use the HMC to complete the steps for installing memory modules. For instructions, see Install a feature using the Hardware Management Console. If you do not have an HMC, complete the following steps to install memory modules:

Parent topic: Model 9116-561 or 570 memory modules

Prepare the system

  1. Perform the prerequisite tasks described in Before you begin.
  2. Stop the system. For instructions, see Stop the system or logical partition.
  3. Disconnect the power source from the system by unplugging the system.
    Note: This system may be equipped with a second power supply. Before continuing with this procedure, ensure that the power source to the system has been completely disconnected.
  4. Remove the front cover from the system unit. For instructions, see Remove the front cover from the model 9116-561 or 570.
  5. If necessary, Disconnect the SMP processor cable from a system unit.
  6. Remove the control panel. For instructions, see Remove the control panel with power off.
  7. Remove the voltage regulator card assemblies, as described in Model 9116-561 or 570 voltage regulator assembly.
  8. Remove the system backplane assembly. For instructions, see Remove the model 9116-561 or 570 system backplane. Skip any steps that you have already completed.
  9. Remove the system processor assembly cover A by unlocking the two retention knobs B and pulling back and lifting up the cover, as shown in the following figure.
    Figure 1. Removing the system processor assembly coverGraphic of removing the processor card assembly cover.
  10. If a Mylar cover is installed over the memory modules, remove the cover.
  11. If necessary, remove memory modules from the processor card assembly. For instructions, see Remove model 9116-561 or 570 memory modules.
  12. Remove the memory module filler, if one is present, by pushing the locking tabs out and then down. The lever action of the tabs forces the memory module filler out of the connector.
  13. Determine the slots in which the memory modules will be placed.
    Notes:
    • Ensure you have read and understand the restrictions and notes at the beginning of this topic, see Model 9116-561 or 570 memory modules.
    • Each processor assembly has eight memory module slots. The memory modules should be plugged into the slots as follows (see Figure 2 for memory module slot locations in the processor assembly):
      • First quad of memory modules is plugged into memory module slots P2-Cx-C1, P2-Cx-C3, P2-Cx-C6, and P2-Cx-C8.
      • Second quad of memory modules is plugged into memory module slots P2-Cx-C2, P2-Cx-C4, P2-Cx-C5, and P2-Cx-C7.
        Figure 2. Memory module slot locations in the processor assembly
        Graphic of the memory module slot locations in the processor assembly.
    • A quad set of 8 GB memory modules can only be installed in a processor card as a set alone, with another 8 GB quad set, or with a 4 GB quad set.
    • For a maximum 16-way configured system, fill additional quads according to the order in Table 1. When adding additional memory modules, begin with the first open quad. If the system is less than a 16-way configured system, eliminate the appropriate number of enclosures and processor cards.

Install memory modules

  1. If necessary, remove the memory module from its antistatic package.
  2. As shown in Figure 3, ensure that the connector locking tabs A are pushed out into the unlocked position before installing a new memory module.
  3. Carefully grasp the memory module B along two edges and align it with the connector.
    Attention: Memory modules are keyed to prevent a memory module from being installed incorrectly. Note the locations of the key tabs within the memory module connector before attempting to install the memory module.
  4. Push the memory module B firmly into the connector until the connector locking tabs A engage.

  5. If you have tall 4 GB or 8 GB memory modules, use the Mylar cover to prevent the memory modules from contacting the lid. When you have finished inserting the memory modules A, place the Mylar cover B over them as shown in Figure 4. If you replace tall 4 GB or 8 GB memory modules with any other size memory modules, remove the Mylar cover. If you do not to remove the Mylar cover it might restrict airflow in the unit.
    Attention: Do not install 8 GB memory modules on a processor assembly with any size memory modules other than 4 GB memory modules. Installing 8 GB memory modules with sizes other than 4 GB memory modules might unconfigure of the other size memory modules and you will see an associated System Reference Code of B123F688. Your system might have other size memory modules on a different processor assembly.

  3. Replace the voltage regulator card assemblies, as described in Model 9116-561 or 570 voltage regulator assembly.
  4. Replace the control panel. For instructions, see Replace the control panel with power off.
  5. Install the front cover. For instructions, see Install the front cover on the model 9116-561 or 570.
  6. Reconnect all power and signal cables to their respective connectors.
  7. Start the system. For instructions, see Start the system or logical partition.
  8. Verify the installed part. For instructions, see Verify the installed part.
  9. If you installed memory modules as part of another procedure, return to the procedure now.
