Installing an Expansion Board — Minitower
To install an expansion board in a minitower system, use the following steps.
1.
Remove the left side cover (see “Removing the Minitower Side Covers”).
2.
Swivel the two feet inward, out of the way.
3.
Position the system unit on its side, with the open left side facing up.
4.
If necessary, slide the system board partway out of the chassis to reach the
expansion board slot (see “Opening the Chassis Floor”).
5. Follow any preinstallation instructions that come with the expansion board
(such as setting jumpers on the board).
6.
Remove and save the screw securing the expansion board locking bracket
(see the figure in “Removing a Slot Cover — Minitower”). Tilt and remove
the bracket and set it aside. You need the bracket to secure the expansion
board in place.
7. From inside the chassis, press out on a slot cover. Save the cover for use in
case the expansion board is removed.

CAUTION
A slot cover can damage the system board or option board if
it falls into the system. If the slot cover does fall into the unit,
remove it before replacing the side cover.

Holding the expansion board by its edges or its bracket, insert the board into
the expansion board slot (see the following figure).
9. Press the board firmly into the expansion board connector on the riser board.
10.
Position the locking bracket in its slot, and then press it up against the top of
the expansion slot frame, locking the board in place.
