Remove a memory module

Use this information to remove a memory module.

About this task

S002

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 and disconnect the power cords and all external cables. 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 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 processor board 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 processor board replacement.

Important

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

Procedure

1. Make preparation for the task.
   1. To replace a front memory module (memory module 33-64), remove the following:
      1. Remove the front top cover. See Remove the front top cover.
      2. Remove the front air baffle. See Remove the front air baffle.
   2. To replace a rear memory module (memory module 1-32), remove the following:
      1. Remove the front top cover. See Remove the front top cover.
      2. Remove the rear top cover. See Remove the rear top cover.
      3. Remove the crossbar. See Remove the crossbar.
      4. Remove all the PCIe risers. See Remove the PCIe riser.
      5. Remove the rear air baffle. See Remove the rear air baffle.
      6. If 2U performance PHMs are installed, remove them to access the memory module slots. See Remove a processor and heat sink.
         Note

         This procedure must be executed by a trained technician.
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.
