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.

Watch the procedure.
  • A video of the installation and removal process is available at YouTube

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.

  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. Disconnect the cables from the M.2 backplane.

  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.
