4 Remove the screw securing the expansion card.
5 Grasp the expansion card by its edges, and carefully remove it from the
expansion-card connector.
6 If you are removing the card permanently, install an expansion-card
slot cover over the empty expansion slot opening, and close the
expansion-card latch.
NOTE: You must install a filler bracket over an empty expansion slot 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.
