4Remove the filler bracket on the slot you will be using.

NOTE: Keep this bracket if you need to remove the expansion card. Filler brackets must be installed over empty expansion card slots to maintain Federal Communications Commission (FCC) certification of the system. The brackets also keep dust and dirt out of the system and aid in proper cooling and airflow inside the system.

5Insert the expansion card firmly into the expansion-card connector on the riser card until the card is fully seated.

NOTE: Ensure that the expansion-card bracket is also inserted into the securing slot on the chassis's back panel.

6Replace the expansion-card retainer. See Figure 3-14.

7Slide the expansion-card sliding retainer to the closed position so that it engages the edge of the expansion card. See Figure 3-15.

8Connect any internal or external cable(s) to the expansion card.

NOTE: You may need to remove the riser card in order to install certain expansion cards with internal connectors. See "Riser Card" on page 79.

9Close the system. See "Closing the System" on page 55.
