ESD Precautions
Integrated circuits on computer boards are sensitive to static
electricity. To avoid damaging chips from electrostatic
discharge, observe the following precautions:
!Do not remove boards or integrated circuits from their anti-
static packaging until you are ready to install them.
!Before handling a board or integrated circuit, touch an
unpainted portion of the system unit chassis for a few
seconds. This helps to discharge any static electricity on
your body.
!Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.

2.2 Inspection
Please read carefully the details explained in Chapter 3
Hardware Descriptionbefore installing the AX10402 into your
system. Pay careful attention to the proper cabling, jumper and
switch settings.
Follow the reminders listed below during installation:
1. Read Chapter 3 “Hardware Description” of this manual.
2. Configure the proper jumper settings.
3. Make sure the power is OFF.
4. Plug the board into a PCI/104 interface connector and fix
it with a screw.
5. Connect the cables. Make sure the connections of the
FDC, HDC, parallel port, serial port and K/B PS/2 mouse
cables are correct.
6. Turn ON the power.
7. If the board does not work, turn OFF the power. Read the
“Hardware Description” chapter carefully and install the
board again.
