Removing and Installing Parts 87
7
Install a filler bracket in the empty card-slot opening. If you are replacing the card, see "Installing PCI
and PCI Express Cards" on page 87.
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.
NOTICE: Before rotating the card retainer back into place, ensure that the tops of all cards and filler brackets are
flush with the alignment bar and the notch in the top of each card or filler bracket fits around the alignment guide.
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.

Installing PCI and PCI Express Cards
NOTICE: To avoid electrostatic discharge and damage to internal components, ground yourself by using a wrist
grounding strap or by periodically touching an unpainted metal surface on the computer chassis.

card, store it in a safe and secure location.

Graphics Card in a Dual Configuration" on page 93 to install a graphics card.
