Figure 128. Removing the expansion card riser (Riser 4) 3. 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. Figure 129. Installing the Riser 1 blank Installing and removing system components 141
