Install the 4 x 3.5" drive backplane and drive cage

Follow instructions in this section to install the 3.5-inch 4-bay drive backplane and drive cage.

About this task

  • 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.

  • The rear drive cage is supported on some server models with thermal requirements. See Thermal rules to ensure that the server is under permitted ambient temperature and the correct heat sink and system fans are used. If needed, replace your heat sink or system fan first.


  1. Touch the static-protective package that contains the new part to any unpainted surface on the outside of the server. Then, take the new part out of the package and place it on a static-protective surface.
  2. Install the drive backplane into the rear drive cage.

    2. Push the top of the backplane so that the holes in the backplane pass through the pins on the drive cage, and close the release latches to secure the backplane in place.
