Chapter 2 Hardware Installation
To set up a PC104-688VL system board, complete the description Chapter 2 and
Chapter 3.
This chapter introduces the system board connectors, jumper settings and then guides
you to apply them for field application.
Before Installation
Before you install the system board, make sure you follow the following descriptions.
1. Before removing the board from its anti-static bag, wear an anti-static strap to
prevent the generation of Electricity Static Discharge (ESD). The ESD may be
created from human body that touches the board. It may do damage to the
board circuit.
2. Install or unplug any connector, module, or add-on card, be sure that the power is
disconnected from the system board. If not, this may damage the system board
components, module, or the add-on-card.
3. Installing a heat sink and cooling fan is necessary for heat dissipation from your
CPU. If heat sink or cooling fan is not mounted, this may cause the CPU fail due to
over-heating problem.
4. When you connect the connectors and memory modules, be careful with the pin
orientations.
