Remove a drive backplane

Use this information to remove a drive backplane.

1. Make preparations for this task.
   1. Turn off the corresponding compute node on which you are going to perform the task.
   2. Remove the compute node from the enclosure (see Remove a compute node from the enclosure).
   3. Remove the components listed below from the compute node in the following order:
      Attention

      To avoid damaging the system board, make sure to follow the instructions in Internal cable routing when disconnecting cables from the system board.

      • Node front cover (see Remove the node front cover).

      • All of the drives and fillers (if any) previously installed and place the drives on the static protective surface (see Remove a hot-swap solid-state drive).

      • The cable connecting the system board and 7mm or 15mm drive backplanes (see 7mm 2.5-inch SATA/NVMe drive backplane cable or 15mm 2.5-inch NVMe drive backplane cable).

      • Drive cage assembly (see Remove the drive cage assembly).

2. Based on your configuration, follow the corresponding procedures to remove two 7mm 2.5-inch SATA/NVMe or one 15mm 2.5-inch NVMe solid-state drive backplane from the drive cage.

   Remove two backplanes for the configuration with two 7mm 2.5-inch SATA/NVMe solid-state drives:

   1. Remove the upper backplane: Remove the three screws from the upper backplane. Slightly tilt and disengage the backplane; then, pull it out of the drive cage at an angle (approximately 30 degrees).

   2. Remove the lower backplane: Remove the two screws and one standoff from the lower backplane. Slightly tilt and disengage the backplane; then, pull it out of the drive cage at an angle (approximately 20 degrees).

   Remove one backplane for the configuration with a 15mm 2.5-inch NVMe solid-state drive:

   1. Remove the three screws from the backplane.
   2. Disengage the backplane and pull it out of the drive cage.
