- If the risers are not going to be replaced, install riser blanks, and if required tighten the captive screws.
NOTE:You must install a filler bracket over an empty expansion card 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.
