Rotate the drive compartment and backplane back into position inside the Controller and ensure that the alignment pins engage.
Note: To confirm that the backplane is locked into position, listen for an audible click or feel the backplane engage with the Controller.
Secure the backplane inside the Controller by inserting the four Phillips Number 2 thumb screws on the four sides of the backplane and tightening them using a Phillips Number 2 screwdriver.
Reconnect all the cables that had been previously disconnected from the backplane.
