Install a memory module

Use this information to install a memory module.

About this task

See Memory module installation rules and order for detailed information about memory configuration and setup.

To avoid potential danger, read and follow the following safety statements.
  • S002
    disconnect all power
    The power-control button on the device and the power switch on the power supply do not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.
  • Read the following section(s) to ensure that you work safely.
  • Power off the server and peripheral devices and disconnect the power cords and all external cables. See Power off the server.

  • Touch the static-protective package that contains the component to any unpainted metal surface on the server; then, remove it from the package and place it on a static-protective surface.

  • Memory modules are sensitive to static discharge and require special handling. In addition to the standard guidelines for Handling static-sensitive devices:
    • Always wear an electrostatic-discharge strap when removing or installing memory modules. Electrostatic-discharge gloves can also be used.

    • Never hold two or more memory modules together so that they touch. Do not stack memory modules directly on top of each other during storage.

    • Never touch the gold memory module connector contacts or allow these contacts to touch the outside of the memory-module connector housing.

    • Handle memory modules with care: never bend, twist, or drop a memory module.

    • Do not use any metal tools (such as jigs or clamps) to handle the memory modules, because the rigid metals may damage the memory modules.

    • Do not insert memory modules while holding packages or passive components, which can cause package cracks or detachment of passive components by the high insertion force.

  1. Locate the memory module slot on the system board.

    Ensure that you observe the installation rules and sequence in Memory module installation rules and order.

  2. Open the retaining clips outward on each end of the memory module slot.

    • To avoid breaking the retaining clips or damaging the memory module slots, handle the clips gently.

    • If necessary, you can use a pointed tool to open the retaining clips due to space constraints. Pencils are not recommended as a tool as they may not be strong enough.

    1. Place the tip of the tool in the recess on the top of the retaining clip.
    2. Carefully rotate the retaining clip away from the memory module slot.
  3. Install the memory module.

    1. Make sure they are in the fully-open position. Align the keys on the memory module with the connector.
    2. Firmly press both ends of the memory module straight down into the connector until the retaining clips snap into the locked position.
