I/O Board I/O board I/O bracket clip ST4 (8 mm) ST3 (8 mm) ST2 (8 mm) I/O bracket ST1 (8 mm) 8 mm Figure A-8. I/O Board Removal To remove and replace the I/O board, follow these steps: 1. Remove the I/O interface cable from connector JSTDIO. See the previous subsection in this appendix. 2. Remove the keyboard/keypad/mouse connector shield. See "Keyboard/Keypad/Mouse Connector Shield" found earlier in this appendix. 3. Remove the four hexagonal standoff screws ST1 through ST4 that secure the serial and parallel port connectors to the I/O panel. Use a 3/16 nut holder to remove the standoff screws. 4. Remove the side I/O bracket clip. See "System Board Assembly" in Chapter 4. 5. Lift the I/O board away from the I/O panel. When replacing the I/O board, make sure that the side I/O bracket clip is positioned so that it rests directly on the I/O board, rather than between the I/O board and I/O bracket (see Figure A-8).
