12 If you installed an add-in network adapter and want to disable the integrated network adapter:
a Enter system setup (see "System Setup" on page 111), go to Onboard Devices and select
Integrated NIC, and then change the setting to Off.
b Connect the network cable to the add-in network adapter’s connectors. Do not connect the
network cable to the integrated connector on the back panel. See "Back Panel Connectors" on
page 14.
13 Install any drivers required for the card as described in the card documentation.
Removing a PCI Card
1 Follow the procedures in "Before You Begin" on page 61.
2 Gently 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.
3 If necessary, disconnect any cables connected to the card. Grasp the card by its top corners and ease it
out of its connector. If a sound card is removed, a jumper should be installed on the Front IO card
audio connector.
4 If you are removing the card permanently, install a filler bracket in the empty card-slot opening.
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.
5 Close the card retention door by snapping it into place to secure the cards.
NOTICE:
To connect a network cable, first plug the cable into the network device and then plug it into the
computer.
6 Replace the computer cover, reconnect the computer and devices to electrical outlets, and then turn
them on.
7 Remove the card’s driver from the operating system.

a Enter system setup (see "System Setup" on page 111), go to Onboard Devices and select
Integrated Audio, and then change the setting to On.
b Connect external audio devices to the audio connectors on the back panel of the computer. See
"Back Panel Connectors" on page 14.
