Expansion Card
The sled supports a low-profile PCIe x16 expansion card installed in the
expansion card riser. To locate the expansion card riser, see Figure 3-24.
Removing the Expansion Card
CAUTION: Many repairs may only be done by a certified service technician. You
should only perform troubleshooting and simple repairs as authorized in your
product documentation, or as directed by the online or telephone service and
support team. Damage due to servicing that is not authorized is not covered by
warranty. Read and follow the safety instructions that came with the product.
CAUTION: Expansion cards can only be installed in the slots on the expansion
card riser. Do not attempt to install expansion cards directly into the riser
connector on the system board.

Once the front cover is detached, turn it over to expose the expansion card
side. See Figure 3-18.

If applicable, disconnect all cables from the expansion card.

Remove the screw securing the expansion card. See Figure 3-18.

Grasp the expansion card by its edges and carefully remove it from the
expansion card riser. See Figure 3-18.

If you are removing the card permanently, install a metal filler bracket over
the empty expansion slot opening, and secure with the screw.
NOTE: 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 sled.
