NOTICE: Do not route card cables over or behind 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 device and then plug the cable into the computer.
NOTE: Installing filler brackets over empty card-slot openings is necessary to maintain FCC certification of the computer. The brackets also keep dust
and dirt out of your computer.
