Removing a PCI Express Card
1. Follow the procedures in "Before you Begin."
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 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 removing the card permanently, install a filler bracket in the empty card-slot opening.
If you need a filler bracket, contact Dell.
