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.
NOTICE:
Do not route card cables over the cards. Cables routed over the cards can prevent the computer cover from closing properly or cause damage
to the equipment.
NOTICE:
To connect a network cable, first plug the cable into the network wall jack and then plug it into the computer.
NOTE:
See the documentation for the card for information about the card's cable connections.
