Removing a PCI Express Card

Follow the procedures in "Before You Begin" on page 59.

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).

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.
