To remove the card, grip the selected internal card at each end of its top edge and pull
the card vertically upwards to release the card from the Chassis.

1. Once the chassis has been removed from the cabinet, undo the top cover retaining
screws on the upper right, rear and left edges of the Controller Chassis.
2. Carefully lift the metal top cover. The internal cards are now visible.
