The system unit has a removable expansion-card cage. The expansion cards fit into connectors on a riser board. Dell recommends that you remove the expansion-card cage first before removing or installing expansion cards.

To remove an expansion-card cage, follow these steps:
1.Disconnect any cables from the expansion cards and the riser board.
2.Rotate the lever toward the back of the system unit until it stops in the upright position.
3.Lift the expansion-card cage up and away from the system unit.
To replace an expansion-card cage, keep the cage flush against the chassis to insure that the lever engages the notch when the lever is depressed.
