Remove a memory module

Use this information to remove a memory module.

About this task

Important

When removing/installing the memory module, do not tilt the memory module and keep it at an upright position to prevent damaging the gap pad.

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.

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

  • 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.

  • 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.

The following illustration shows the location of the memory module connectors on the system board.

The following illustration might differ slightly from your hardware, but the installation method is the same.

Procedure

Note
  • 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.

  • Depending on the model, your solution might look slightly different from the illustration.

    Note
    Memory module tool is recommended due to space limitations caused by location of water loop tubes through the memory section.
  3. Remove the DIMM cover.
    Note
    Do not tilt the DIMM cover and keep it at an upright position to prevent damaging the gap pads.
