4Disconnect the PS/2 serial adapter cable from the system board (see "System Board Components" on page 32).

5If necessary, disconnect any external cables connected to the adapter.

6Ease the PS/2 serial-port adapter bracket out of its retention slot.

7If 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 and maintains the airflow that cools your computer.

•The notch in the top of the card or filler bracket fits around the alignment guide.
