Install the 3.5-inch middle drive cage

Use this information to install the middle 3.5-inch drive cage.

About this task

The middle drive cage is supported on some server models at certain conditions. For detailed information, see Technical rules.

  • Read Installation Guidelines to ensure that you work safely.

  • 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.


  1. Connect cables to the backplane.
  2. Align the bottom of the backplane with the studs at the bottom of the drive cage. Rotate the backplane to vertical position so that the holes in the backplane pass through the pins on the drive cage, and press the backplane into position. The release latches will secure the backplane in place.
