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 all external cables from the enclosure.

• 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.

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