Install the middle drive cage

Use this information to install the middle drive cage.

About this task

  • Read Installation Guidelines to ensure that you work safely.

  • Power off the server and disconnect all power cords for this task.

  • 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 middle 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.

  • When there is only one processor installed, six system fans are needed if a middle drive cage, rear drive cage, or riser 3 is installed.

  • If you are upgrading the server to the 32 x 2.5-inch NVMe configuration, replace your cable wall bracket first. See Cable wall brackets replacement.


  1. Install the middle drive cage and drives.
    • The illustration shows installing the 2.5-inch middle drive cage. The procedure is the same for installing the 3.5-inch middle drive cage.

    • If any cables need to go through beneath the middle cage, route the cables before installing the middle cage.
