Replacing the PCI and PCI Express Cards
CAUTION: To avoid electrostatic discharge and damage to internal components,
ground yourself by using a wrist grounding strap or by periodically touching an
unpainted metal surface on the computer chassis.
CAUTION: If your computer came with a PCI graphics card installed, removal of
the card is not necessary when installing additional graphics cards; however, the
card is required for troubleshooting purposes. If you remove the card, store it in a
safe and secure location.
1 Follow the procedures in "Before You Begin" on page 13.
2 Remove the computer cover (see "Replacing the Computer Cover" on
page 17).
3 Disconnect any cables connected to the card.
4 If the card is a full length, remove the captive screws on top of the PCI
card fan shroud and remove the shroud.
5 Remove the card retention screw.
