Expansion Cards

Installing an Expansion Card

1. Turn off the computer and peripherals, disconnect them from their electrical outlets, wait at least 5 seconds, and then remove the computer cover.

2. Lay the computer on its right side.

3. Prepare the expansion card for installation.

See the documentation that came with the expansion card for information on configuring the card, making internal connections, or otherwise customizing

it for your system.

4. If you are installing an AGP card, remove the AGP card brace.

5. Remove the screw that secures the expansion slot filler bracket to the chassis, and remove the bracket from the chassis (see the following figure).

Save the screw to use when installing the expansion card later in this procedure.

Removing the Filler Bracket

NOTE: To meet PC99 system requirements, your Dell computer uses only PCI expansion slots. Industry-Standard Architecture (ISA) expansion cards are

not supported. This is an industry standard for ease-of-use.

NOTICE: Before disconnecting a peripheral device from the computer, wait 10 to 20 seconds after disconnecting the computer from its electrical outlet.

Before removing a component from the system board, verify that the standby power light on the system board has turned off. To locate this light, see

"System Board Components."

CAUTION: Before you perform this procedure, see "Safety First— For You and Your Computer."
