Install a memory module

Follow the instructions in this section to install 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.
See Memory module installation rules and order for detailed information about memory configuration and setup.
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 the server is installed in a rack, slide the server out on its rack slide rails to gain access to the top covers, or remove the server from the rack. See Remove the server from rails.

  • Make sure to adopt one of the supported configurations listed in Memory module installation rules and order.

  • Memory modules are sensitive to static discharge and require special handling. Refer to the standard guidelines at 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.

  • Before installing 24 Gb DRAM RDIMMs, make sure to update the UEFI firmware to the latest version first, then remove all existing 16 Gb DRAM RDIMMs.

Firmware and driver download: You might need to update the firmware or driver after replacing a component.

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. Locate the required memory module slot on the system board assembly.
    Note
  2. Touch the static-protective package that contains the memory module to any unpainted surface on the outside of the server. Then, take the memory module out of the package and place it on a static-protective surface.
  3. Install the memory module into the slot.
    Attention
    • To avoid breaking the retaining clips or damaging the memory module slots, open and close the clips gently.
    • If there is a gap between the memory module and the retaining clips, the memory module has not been correctly inserted. In this case, open the retaining clips, remove the memory module, and then reinsert it.

    1. Gently open the retaining clip on each end of the memory module slot.
    2. Align the memory module with the slot, and gently place the memory module on the slot with both hands.
    3. Firmly press both ends of the memory module straight down into the slot until the retaining clips snap into the locked position.

After you finish

  1. If you replaced a front memory module, reinstall the following:
    1. Reinstall the front air baffle. See Install the front air baffle.
    2. Reinstall the front top cover. See Install the front top cover.
  2. If you replaced a rear memory module, reinstall the following:
    1. If 2U performance PHMs were removed to access the memory modules, reinstall them. See Install a processor and heat sink.
    2. Reinstall the rear air baffle. See Install the rear air baffle.
    3. Reinstall all the PCIe risers. See Install the PCIe riser.
    4. Reinstall the crossbar. See Install the crossbar.
    5. Reinstall the rear top cover. See Install the rear top cover.
    6. Reinstall the front top cover. See Install the front top cover.

  3. Complete the parts replacement. See Complete the parts replacement.
