b.As you slide the controller into the empty slot, make sure the guide pins on the side of the controller fit into the notches. After the guide pins fit into the notches and the controller fits snugly into the bay, push the lever downward or upward 90°, depending on whether the controller is inserted in the A or B controller bay to fully latch it into place. Do not force fit. The controller is designed to prevent it from being inserted into the chassis incorrectly.

Attention: Make sure that the levers lock into place in the storage subsystem chassis.
