NOTE: Installing filler brackets over empty card-slot openings is necessary to maintain FCC certification of the computer. The brackets keep dust and dirt out of your computer and maintain the airflow that cools your computer. 9 Before you close the card retention mechanism, ensure that: • The tops of all cards and filler brackets are flush with the alignment bar. • The notch in the top of the card or filler bracket fits around the alignment guide. 10 Secure any remaining card(s) by closing the card retention latch and snapping it into place.
