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 97.
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.

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:

computer cover from closing properly or cause damage to the equipment.
8 Rotate the card retainer back into its original position; push its tip so that its tab clicks into place.
NOTICE:
To connect a network cable, first plug the cable into the network port or device and then plug the cable
into the computer.

computer and devices to electrical outlets, and then turn them on.

If you removed a sound card or a network adapter, see "Network Adapter and Sound Card Settings" on
