Remove a memory module

Use this information 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 peripheral devices, disconnect the power cords from the primary chassis, then disconnect the power cords from the secondary chassis. See Power off the server.

  • 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.

  • If the server is installed in a rack, remove the server from the rack. See Remove the server from rails.

  • If you are not installing a replacement memory module to the same slot, make sure you have memory module filler available.

  • 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.

  • In the case of upper processor board (CPU BD) or lower processor board (MB) replacement, keep records of the slots in which the modules are installed, and make sure to install them back to the exact same slots after upper processor board (CPU BD) or lower processor board (MB) replacement.

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 preparation for the task.
    1. To replace a memory module on the upper processor board (CPU BD), remove the following:
      1. Remove the front top cover. See Remove the front top cover.
      2. Remove the upper processor board (CPU BD) air baffle. See Remove the upper processor board (CPU BD) air baffle.
    2. To replace a memory module on the lower processor board (MB), remove the following:
      1. Remove the front top cover. See Remove the front top cover.
      2. Remove the upper processor board (CPU BD) air baffle. See Remove the upper processor board (CPU BD) air baffle.
      3. Remove the upper processor board (CPU BD). See Remove the upper processor board (CPU BD).
      4. Remove the lower processor board (MB) air baffle. See Remove the lower processor board (MB) air baffle.
  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.
    Figure 1. Memory module removal
    Memory module removal
    1. Gently open the retaining clip on each end of the memory module slot.
    2. Grasp the memory module at both ends and carefully lift it out of the slot.

After you finish

  1. Install a memory module or a memory module filler. See Install a memory module.

    Note
    A memory module slot must be installed with a memory module or a memory module filler.

  2. If you are instructed to return the component or optional device, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.
