5 Remove the filler bracket on the slot you will be using.
NOTE:
Keep this bracket if you need to remove the expansion card. Filler brackets must be installed over empty
expansion-card slots 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.
6 Align the expansion card with the card-edge guides and insert the expansion card firmly into the
expansion-card connector until the card is fully seated.
NOTE:
Ensure that the expansion-card bracket is also inserted into the securing slot on the back of the
expansion-card cage.
7 Close the expansion-card retainer. See Figure 3-9.
8 If applicable, reinstall the expansion-card stabilizer:
