the three cover hooks into the rectangular slots on
the chassis. (It may be helpful to look down into the
chassis to verify that the hooks are in place.)

R
emoving and Replacing the
Expansion-Card Cage
Your Dell computer has a removable expansion-card
cage, which greatly simplifies many installation proce-
dures by allowing you to remove the riser board and all
installed expansion cards in a single step.
Removing the Expansion-Card Cage
Use the following procedure to remove the expansion-
card cage:
1.
Remove the computer cover as instructed in
“Removing the Computer Cover” found earlier
in this chapter.
2.
Check any cables connected to expansion cards
through the back-panel openings. Disconnect any
cables that will not reach to where the cage must
be placed while removed from the chassis.
3.
Locate the card-cage securing lever (see Fig-
ure 5-4). Rotate the lever upward until it stops in
an upright position.

Card Cage

Lift the expansion-card cage up and away from
the chassis.
