Dell XPS 730 (Late 2008) - Manual (Page 39)

Replacing a PCI/PCI Express Card 37
7 Install a filler bracket in the empty card-slot opening. If you are replacing
the card, see "Replacing a PCI/PCI Express Card" on page 27.
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.
CAUTION: 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.
8 Reinstall the card retention screw.
9 Reinstall the card slot fan shroud.
10 Replace the computer cover (see "Replacing the Computer Cover" on
page 17), reconnect the computer and devices to electrical outlets, and
then turn them on.
11 Uninstall the driver for the card that you removed.
CAUTION: If you have or are upgrading to the optional multi-graphics
configuration, see "Installing Graphics Cards for Multi Graphics Card" on page 31
to install a graphics card.
12 If present, press the tab on the graphics card bridge that lays over the
installed cards and rotate it upwards to gain full access to the card.
