Your Dell computer has a removable expansion-card cage, which simplifies many
installation procedures by allowing you to remove the riser board and all installed
expansion cards in a single step.
To remove the expansion-card cage, perform the following steps:
1. Turn off the system, including any attached peripherals, and disconnect the sys-
tem from the electrical outlet.

2. Open the computer doors.
3. Check any cables connected to expansion cards through the back-panel open-
ings. Disconnect any cables that will not reach to where the cage must be placed
upon removal from the chassis.
NOTE: Verify that the power LED on the riser board (see Figure 7-3) is off before
removing the card cage.
