Installing a PCI Express Card
1 Follow the procedures in "Before You Begin" on page 47.
2 If you are installing a new card, unscrew and remove the filler bracket to create a card-slot
opening. Then continue with step 4.
3 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. If your card includes a retention
mechanism, remove the top of the retention mechanism by pressing the tab and pulling up
on the top. Gently pull the securing tab, grasp the card by its top corners, and then ease it out
of its connector.
