expansion-card connector.

over the empty expansion slot opening, and close the expansion-card

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.
