Prerequisites

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 by Dell is not covered by your warranty. Read and follow

the safety instructions that are shipped with your product.

1. Follow the safety guidelines listed in the Safety instructions section.

2. Follow the procedure listed in the Before working inside your system section.

3. When removing a card from riser 3, ensure that the PCIe holder latch is closed.

NOTE: The procedure for installing and removing a full length PCIe card is similar to the procedure for removing and

installing a GPU card.

Steps

1. Disconnect any cables connected to the expansion card.

2. Lift the expansion card latch out of the guide slot.

3. Hold the expansion card by its edges, and remove it from the expansion card connector.

4. If you are removing the card permanently, install a metal filler bracket over the empty expansion slot opening and close the expansion

card latch.

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.

5. Install the expansion card latch into the slot.

6. Close the expansion card locking tabs.
