Grasp the expansion card by its edges, and carefully remove it from the 
expansion-card connector.

If you are removing the card permanently, install a metal filler bracket 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.
