Adding Other Cards

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide.

NOTICE: You must use low-profile cards for your computer. A full-size card can cause damage to the computer or the card.

The computer’s card connectors allow you to install different types of devices such as modems and network adapters.

1Shut down the computer through the Start menu (see page 21).

2Ensure that your computer and attached devices are turned off. If your computer and attached devices did not automatically turn off when you shut down your computer, turn them off now.

NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it from the network wall jack.

3Disconnect any telephone or telecommunication lines from the computer.

4Disconnect your computer and all attached devices from their electrical outlets, and then press the power button to ground the system board.

5Remove the computer stand (see page 12).

CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before opening the cover.

6Open the computer cover (see page 58).

7Press the lever on the retention arm and raise the retention arm.

8If you are installing a new card, remove the filler bracket to create an empty card-slot opening.

If you are replacing a card that is already installed in the computer, remove the card. If necessary, disconnect any cables connected to the card. Grasp the card by its top corners, and ease it out of its connector.

9Prepare the card for installation.

See the documentation that came with the card for information on configuring the card, making internal connections, or otherwise customizing it for your computer.

CAUTION: Some network adapters automatically start the computer when they are connected to a network. To guard against electrical shock, be sure to unplug your computer from its electrical outlet before installing any cards.

10Insert the card into the card connector.

If the card is full-length, insert the end of the card into the card guide bracket as you lower the card toward its connector on the system board. Insert the card firmly into the card connector on the riser board.
