Removing a PCI Express Card

1. Follow the procedures in "Before You Begin."

2. Gently push the release tab on the card retention latch from the inside to pivot the latch open. Because the latch is

captive, it will remain in the open position.

a. Place your thumb on the top of the card retention mechanism and grip the bottom of the retention mechanism

with your fingers.

b. With your free hand, gently squeeze the sides of the retention mechanism to release it from the tab slots

holding it in place.

c. Pivot the retention mechanism upward to release it from the two tab slots.

d. Set the retention mechanism aside in your work area.

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.

NOTE: Installing filler brackets over empty card-slot openings is necessary to maintain FCC certification of the

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

5. Re-seat the card retention mechanism in the tabs and pivot downward to snap it into place.Lower the retention arm

and press it into place.
