Removing memory modules from the 8231-E2B, 8231-E1C, 8231-E1D, 8231-E2C, 8231-E2D, or 8268-E1D

Use this procedure to remove a memory module before installing a replacement memory module.

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. Identify the failing 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 is 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. Remove the memory riser from the system by pulling the locking tabs into the open position and lifting the memory riser out of the system.

10. Identify the failing memory module by pressing the blue button (B) on the memory riser. Pressing the blue button activates the LED (A) associated with the failing dual inline memory module (DIMM).
    Note: While the system is in the service position, DIMM fault and identify LEDs are not visible for DIMM locations C3 and C4. To identify the correct DIMM by its LED for these locations, you must first remove the memory riser and press the blue service button, which activates the LED. For instructions, see Removing memory risers from the 8231-E2B, 8231-E1C, 8231-E1D, 8231-E2C, 8231-E2D, or 8268-E1D.

11. Remove the memory module as follows. Unlock the memory module by pushing the locking tabs (A) open, as shown in Figure 3. Lift the memory module (B) out of the connector. The lever action of the tabs forces the memory module out of the connector.
