Remove the M.2 backplane assembly

Use this information to remove the M.2 backplane assembly.

About this task

Attention

  • Read Safety inspection checklist and Installation Guidelines to ensure that you work safely.

  • Power off the corresponding compute node that you are going to perform the task on.

  • Remove the compute node from the chassis. See Remove the compute node from chassis.

  • Before you make changes to the drives, drive controllers, drive backplanes, or drive cables, make sure to back up all important data stored in drives.

  • Before you remove any component of a RAID array (drive, RAID card, etc.), back up all RAID configuration information.

  • Make sure you have the M.2 backplane assembly filler available if no M.2 backplane assembly is going to be installed after the removal.

Procedure

  1. Make preparations for your compute node.
    1. Remove the compute node cover. See Remove the compute node cover.
    2. If there is an I/O expansion adapter installed in I/O expansion connector 2, remove it from the compute node. See System-board layout and Remove an I/O expansion adapter.
  2. Disconnect the M.2 backplane assembly cables from system board.
    1. Press and hold the latches on the M.2 cables.
    2. Disconnect the cables from system board.

    Attention
    Strictly observe the following instructions to avoid damaging cable sockets on the system board. Any damage to the cable sockets might require replacing the system board.

    • Connect cable connectors vertically or horizontally in alignment with the orientations of the corresponding cable sockets, avoiding any tilt.

    • To disconnect cables from the system board, do as follows:

      1. Press and hold all latches, release tabs, or locks on cable connectors to release the cable connectors.

      2. Remove the cable connectors vertically or horizontally in alignment with the orientations of the corresponding cable sockets, avoiding any tilt.
        Note
        The cable connectors might look different from those in the illustration, but the removal procedure is the same.






  3. Disconnect the M.2 backplane assembly cables from the M.2 backplane.
    1. Loosen the screw that secures the signal cable to the M.2 backplane.
    2. Tilt the connector.
    3. Remove the connector.
    4. Remove the power cable.

  4. Remove the M.2 backplane from the air baffle.
    1. Loosen the screw that secures the M.2 backplane to air baffle.
    2. Slide the M.2 backplane forward and lift it up from the air baffle.

    Attention
    To maintain proper system cooling, do not operate the compute node without an M.2 backplane assembly or an M.2 backplane assembly filler installed on the air baffle.
After you finish
  • If no M.2 backplane assembly is going to be installed to the air baffle, complete the following:

    1. Reinstall the removed I/O expansion adapter back to I/O expansion adapter connector 2 if needed. See System-board layout and Install an I/O expansion adapter

      .

    2. Install the M.2 backplane assembly filler on the air baffle. See Install the M.2 backplane assembly filler.

  • 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.
