Removing and Installing Parts
Installing a PCI Express Card
1
Follow the procedures in "Before You Begin" on page 59.
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 (see "Installing a PCI Card" on page 74 for an
illustration of the card retention door).
3
If 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.
4
If you are installing a new card, remove the filler bracket to create a card-slot opening. Then continue
with step 5.
5
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.
