I/O Board
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).
