Remove the rear M.2 riser cage and drive backplane

Follow the instructions in this section to remove the rear M.2 riser cage and drive backplane.

About this task

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.

  • Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-sensitive components in their static-protective packages until installation, and handling these devices with an electrostatic-discharge wrist strap or other grounding system.

Procedure

  1. Make preparations for this task.
    1. If the server is installed in a rack, slide the server out on its rack slide rails to gain access to the top cover, or remove the server from the rack. See Server replacement.
    2. Remove all hot-swap M.2 drive assemblies installed at rear of the server. See Remove a hot-swap M.2 drive assembly.
    3. Remove the top cover. See Remove the top cover.
  2. If the rear M.2 backplane is installed in a 3FH M.2 riser cage, do the following:
    1. Disconnect riser card cables, PCIe adapter cables, the M.2 backplane power and signal cables from the system board assembly.
      Attention
      To avoid damaging the system board assembly, make sure to follow the instructions in Internal cable routing when disconnecting cables from the system board assembly.
    2. Remove the M.2 riser cage that the M.2 backplane is installed in. See Remove a rear riser assembly.
    3. Remove all the PCIe adapters installed in the riser assembly. See Remove a rear PCIe adapter and riser card.
  3. If the rear M.2 backplane is installed in a 1FH M.2 riser cage, do the following:
    1. If applicable, remove the rear drive cage and the rear riser assembly that are on the top of 1FH M.2 riser cage. See Rear drive cage replacement and Remove a rear riser assembly.
    2. Disconnect the M.2 backplane power and signal cables from the system board assembly; then, remove the 1FH M.2 riser cage from the chassis. See Remove a rear riser assembly.
  4. Disconnect the M.2 backplane power and signal cables from the M.2 backplane.
  5. Remove the M.2 backplane from the M.2 riser cage.
    1. Loosen the screw that secures the backplane.
    2. Slide the backplane away from the cage; then, lift the backplane to remove it.
