Figure 146. Removing the expansion card riser (Riser 4)
2.
If the risers are not going to be replaced, install riser blanks and 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.
