Removing a PCI Express Card

1Follow the procedures in "Before You Begin" on page 53.

2Gently push the release tab on the card retention door from the inside to pivot the door open. Because the door is captive, it will remain in the open position. (See page 67 for an illustration of the card retention door.)

3If your computer includes a card retention mechanism, to secure the x16 card in place from the top:

a Pivot the mechanism upward and gently squeeze in on the sides to release the mechanism from the two tab slots holding it in place.

b Set the retention mechanism aside in a secure location.

4If you are removing the card permanently, install a filler bracket in the empty card-slot opening. If you need a filler bracket, contact Dell (see page 116).

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.

5Reseat the card retention mechanism in the tabs and pivot downward to snap it into place.

6Close the card retention door to snap it into place, securing the card(s).

NOTICE: To connect a network cable, first plug the cable into the network device and then plug it into the computer.

7Replace the computer cover, reconnect the computer and devices to electrical outlets, and then turn them on.

8Remove the card’s driver from the operating system.

9If you removed a sound card:

a Enter system setup (see page 103), select Audio Controller, and then change the setting to On. b Connect external audio devices to the audio connectors on the back panel of the computer.

10If you removed an add-in network connector:
