How to Install the PCI Card

  1. Unplug your computer. Power down your computer and then unplug the power cable and all the other cables that are connected to the back.
  2. Open your computer. PCI cards need to be installed inside your computer's chassis.
  3. Remove the metal bay cover. Each PCI slot will have a bay associated with it on the back of the computer. When there's nothing installed, the bays are covered by small metal protectors. You can remove one by unscrewing the single screw holding it in place and then lifting it directly out of the case. Set the screw aside.
  4. Gripping the PCI card by the sides. Do not touch the contacts along the bottom, and try to avoid touching any of the circuitry.
  5. Insert the card. Press it firmly straight down into the slot. Ensure that the card is level and seated fully in the slot before continuing. Note that the X650 PCI card is not required to insert into PCI slot on the motherboard.
  6. Secure the card. Use the screw that you removed from the metal bay cover and use it to secure the card into the same hole. Tighten the screw firmly but not so tightly that it will strip later.
