Expansion Cards
The computer has a removable expansion-card cage. The expansion-card cage
contains the riser board and any installed expansion cards. Dell recommends
that you remove the expansion-card cage first before removing or installing
expansion cards.
If you are not removing any expansion cards, leave the external cables attached
to the expansion cards.
