Remove a memory module

Follow the instructions in this section to remove a memory module.

About this task

S002
disconnect all power
CAUTION
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.
Attention
  • Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.

  • Power off the server and disconnect all power cords for this task. See Power off the server.

  • If the server is in a rack, remove it from the rack.

  • If foot stands are installed on the server, pivot them inwards and lay the server on its side for easier operation.

  • 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. Refer 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 do not touch each other. 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.

Important

Remove or install memory modules for one processor at a time.

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 server cover. See Remove the server cover.
    2. If necessary, remove all flash power modules. See Remove a flash power module.
    3. Remove the air baffle. See Remove the air baffle.
    4. If necessary, remove the installed A2/L4 GPU air duct(s), FL PCIe adapter holder, or FL GPU adapter(s) (see Remove an A2/L4 GPU air duct, Remove a FL PCIe adapter holder, or Remove a FL GPU adapter).
      Note
      This step is optional. Do this step if the removal or installation of the DIMM cannot be proceeded smoothly with the A2/L4 GPU air duct(s), FL PCIe adapter holder(s), or FL GPU adapter(s) installed in place.
    5. Locate the memory module slots and determine which memory module is to be removed from the server.
      Important

      Remove or install memory modules for one processor at a time.

  2. Remove the memory module from the slot.
    Attention
    To avoid breaking the retaining clips or damaging the memory module slots, handle the clips gently.
    1. Open the retaining clip at each end of the memory module slot.
    2. Hold both ends of the memory module and carefully lift it out of the slot.
