To reinstall the storage drive cage and motherboard assembly, follow these steps:

Tilt the motherboard to the right side to fit under the power supply assembly, level the motherboard and place it into the server chassis, then slide it to the rear of the server to engage the standoffs.

3. Slide the disk cage back into the chassis and apply pressure to the front of the cage to engage the standoffs in the base of the chassis.

   Ensure that the bottom front edge of the chassis engages into the front slot(s) on the front bottom edge of the storage drive cage.

4. Depending on your server’s storage drive configuration, do one of the following:
   • If your server is configured with twenty-four 2.5-inch drives, replace the disk cage assembly:
     1. Replace the four No. 2 Phillips screws (two on each side of the chassis) that secure the disk cage assembly to the server chassis.
     2. Install the server fan assembly door.

        See "Install the Fan Assembly Door" on page 161 in the Service Manual.

   • If your server is configured with twelve 3.5-inch eight drives or eight 2.5-inch drives, replace the disk cage assembly:
     1. Replace the six No. 2 Phillips screws (three on each side of the chassis) that secure the storage drive cage to the server chassis.
5. Reconnect the cables to the storage drive backplane(s).

   Reconnect the disk backplane LED cable, the SAS/SATA cable(s), the power cable(s), and the DVD power cable (eight-drive systems only).

   • For eight-drive and twelve-drive systems, see Step 3 in the procedure "Install the Storage Drive Backplane for Eight-Drive and Twelve-Drive Systems" on page 122 in the Service Manual.
