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.

Figure 4-16. Expansion-Card Cage Removal
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.
