Removing a PCI Express Card
1
Follow the procedures in "Before You Begin" on page 53.

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 page 68 for an illustration 
of the card retention door.)

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.

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 (see page 118).

of the computer. The brackets also keep dust and dirt out of your computer.
