Remove the 12-Drive Backplane

To remove the 12-Drive backplane (DBP):

  1. Prepare the server for service.
    1. Power off the server.
    2. Disconnect the power cords from the power supplies.
    3. Extend the server into the maintenance position.
    4. Attach an antistatic wrist strap to your wrist, and then to a metal area on the chassis.
    5. Remove the server top cover.
    6. Remove the air baffle.
    7. Remove the fan modules from the server.
    8. Remove the fan tray from the server.
  2. Pull each storage drive out far enough to disengage it from the backplane.

    See Remove a Storage Drive.

    Note:

    It is not necessary to completely remove the storage drives from the server; simply pull them out far enough to disengage them from the backplane. If you do remove the storage drives from the server, make a note of their locations so that you can reinstall them in the same locations.
  3. Disconnect the cables from the disk backplane.

    Ensure all cables are moved out of the way so they do not interfere with the disk backplane removal procedure.

    1. Disconnect the three SAS cables from the 12-Drive backplane [1].
    2. Disconnect the two power cables from the 12-Drive backplane [2].

      Press and hold the button on the connector to disengage the locking mechanism, then gently pull the connector from the disk backplane. Note the cable connections in order to ease proper reconnection of the cables.

      Figure showing the 12-Disk backplane being removed from the server.
    3. Disconnect the DBP auxiliary signal cable from the 12-Drive backplane [3].
  4. Using a Torx T15 screwdriver, loosen the right-side and left-side spring-mounted screws that secure the 12-Drive backplane to the chassis [4].
  5. Lift the 12-Drive backplane up to release it from the standoff hooks and out of the chassis [5 and 6].
  6. Place the 12-Drive backplane on an antistatic mat.
