Installing memory risers in the 8231-E2B, 8231-E1C, 8231-E1D, 8231-E2C, 8231-E2D, or 8268-E1D

Use this procedure to install new memory risers.

1. Identify the system that you will be working on by using the identify the system process to turn on the system locate (blue) indicator. For more information, see Enabling enclosure indicators and Control panel LEDs.
2. Complete the prerequisite tasks. For instructions, see Before you begin.
3. Place the system into the service position. For instructions, see Placing a rack-mounted model into the service position.
4. Remove the service access cover. For instructions, see Removing the service access cover from a rack-mounted model.
5. Use the service indicator light-emitting diodes (LEDs) to help identify the part. For instructions, see Identifying a part.
6. Stop the system. For instructions, see Stopping a system or logical partition.
7. Disconnect the power source from the system by unplugging the system. For instructions, see Disconnecting the power cords.
   Note: A second optional power supply is available with this system. Before continuing with this procedure, ensure that the power source to the system has been disconnected.

8. 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 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.
9. Determine the location where the memory riser will be installed. Each processor module has two memory card (riser) slots with four memory module slots on each memory riser card. See Memory riser placement and memory module balancing to ensure that memory modules associated with each processor module are balanced.
10. Remove the memory riser filler from the location where the new memory riser will be installed.
11. Install the memory modules on the memory riser. For instructions, see Installing memory modules in the 8231-E2B, 8231-E1C, 8231-E1D, 8231-E2C, 8231-E2D, or 8268-E1D.
12. Install the memory riser.
    1. Align the memory riser with the plastic guides on the memory cage. The memory modules or dual inline memory modules (DIMMs) must face to the right.
    2. Slide the memory riser into the cage until it stops just above the connector.
    3. Press the locking tabs into the closed position until they snap into place.

13. If you are installing memory modules as part of another procedure, return to that procedure now. If your service actions are complete, continue with the following steps:
    1. Replace the service access cover. For instructions, see Installing the service access cover on a rack-mounted model.
    2. Place the system in the operating position. For instructions, see Placing a rack-mounted model into the operating position.
    3. Reconnect the power source.
    4. Start the system.
       • If you are installing or removing system memory and the following conditions are true, set the power-on mode to Partition Standby.
         • The system is managed by the HMC.
         • The only logical partition is assigned all system resources.
         Start the system as described in Power On.
       • For all other conditions, start the system as described in Starting a system or logical partition.
    5. Verify the installed part or repair.
       • If you replaced the part because of a service action, verify the installed part as described in Verifying the repair.
       • If you installed the part for any other reason, verify the installed part as described in Verifying the installed part.
