To install or replace a PCI card, do the following:
1. Remove all media from the drives and turn off all attached devices and the computer. Then, disconnect
all power cords from electrical outlets and disconnect all cables that are connected to the computer.
2. Remove the computer cover. See “Removing the computer cover” on page 101.
3. Do one of the following:
• If you are replacing a PCI card, remove the screw that secure the old PCI card and release the old
PCI card from the PCI card slot. Then, carefully remove the old PCI card from the chassis, as shown

then disconnect the cables.
