Remove a memory module

Use this information to remove a memory module.

About this task

Attention

  • Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.

  • Turn off the corresponding DWC tray that you are going to perform the task on.

  • Disconnect the power cords and all external cables from the enclosure.

  • Disconnect the power cords from the enclosure.

  • Make sure to remove or install memory module 20 seconds after disconnecting power cords from the system. It allows the system to be completely discharged of electricity and safe for handling memory module.

  • Use extra force to disconnect QSFP cables if they are connected to the solution.

  • 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.

  • Before installing 24 Gb DRAM RDIMMs to a system with 4th Gen Intel Xeon processors (codenamed Sapphire Rapids), make sure to update the UEFI firmware to the latest version first, then remove all existing 16 Gb DRAM RDIMMs.

Procedure

Attention

Make sure to remove or install memory module 20 seconds after disconnecting power cords from the system. It allows the system to be completely discharged of electricity and safe for handling memory module.

  1. Make preparations for this task.
    1. Remove the tray from the enclosure. See Remove a DWC tray from the enclosure.
    2. Remove the tray cover. See Remove the tray cover.
  2. Remove the memory module tool attached to the DIMM comb.

    Note
    Memory module tool is recommended due to space limitations caused by location of water loop tubes through the memory section.
  3. Unlock the retaining clips on each end of the memory module connector with the memory module tool.
    1. Place the tip of the tool on the top of the retaining clip.
    2. Press the tool to rotate and unlock the retaining clip.

    Attention

    • Memory modules are static-sensitive devices. The package must be grounded before it is opened.

    • To avoid breaking the retaining clips or damaging the memory module connectors, open and close the clips gently.

  4. Hold the right end and left end of the memory module at the same time. Keep the memory module in parallel with the connector; then, carefully remove the memory module.
