Remove the Storage Drive Backplane

  1. Prepare the storage server for service.
    1. Power off the storage server and disconnect the power cords from the power supplies.

      See Powering Down the Storage Server.

    2. Extend the storage server into the maintenance position.

      See Extend the Storage Server to the Maintenance Position.

    3. Attach an antistatic wrist strap to your wrist, and then to a metal area on the chassis.

      See Take Antistatic Measures.

    4. Open the storage server fan assembly door, and remove the fan modules from the storage server.

      See Remove a Fan Module.

    5. Remove the fan assembly door from the storage server.

      See Remove the Fan Assembly Door From the Storage Server.

  2. Pull each storage drive out far enough to disengage if from the disk backplane.

    See Remove a Storage Drive.


    Note -  It is not necessary to completely remove the storage drives from the storage server; simply pull them out far enough to disengage them from the disk backplane. If you do remove the storage drives from the storage server, record their locations so that you can reinstall them in the same locations.
  3. Disconnect the cables from the storage drive backplane.
    1. Disconnect the two power cables and the auxiliary signal cable from the storage drive backplane [1].
    2. Disconnect the twelve NVMe cables from the storage drive backplane [2].

      Note the cable connections in order to ease proper reconnection of the cables.

  4. Using a No. 2 Phillips screwdriver, loosen the two spring-mounted screws that secure the storage drive backplane to the chassis [3].

    Note -  Due to its location, the left spring-mounted screw might be difficult to remove with a standard No. 2 Phillips screwdriver. If you experience difficulty removing the screw, use a long No. 2 Phillips screwdriver or a torque driver with a long extension.
  5. Lift the storage drive backplane up to release it from the standoff hooks, and then pull it away from the standoff hooks and out of the chassis [3].
  6. Place the storage drive backplane on an antistatic mat.
