3 Disconnect the PS/2 serial adapter cable from the system board (see "System Board Components" on
page 28).
4 If necessary, disconnect any external cables connected to the adapter.
5 Grasp the PS/2 serial-port adapter bracket by its top corners, and ease it out of its retention slot.
6 If you are removing the adapter permanently, install a filler bracket in the empty card-slot opening.
NOTE:
Installing filler brackets over empty card-slot openings is necessary to maintain FCC certification of the
computer. The brackets also keep dust and dirt out of your computer.
7 Before you close the card retention mechanism, ensure that:
• The tops of all cards and filler brackets are flush with the alignment bar.
• The notch in the top of the card or filler bracket fits around the alignment guide.
8 Secure the card(s) by closing the card retention latch and snapping it into place.
9 Replace the computer cover (see "Replacing the Computer Cover" on page 297).
