the factory, expansion boards are plugged into the main system unit’s mother board.
There are expansion boards available for a wide variety of functions.- The most common expansion boards provide such functions as extra I/O ports, high resolution video graphics and system memory expansion.
The basic computer is shipped from the factory with only the system motherboard installed. If you have purchased a system with a video monitor or a hard disk system installed, the necessary controller board(s) should also be installed. If you are adding these systems to a basic computer, or expanding your system by installing additional hardware, follow the procedure below to install the circuit boards.
First, read all of the instructions provided with the expansion product. Then, carefully unpack the circuit board(s) to be installed.
Warning!
Most computer circuit boards have “static sensitive” components on them. These parts can be damaged by static electricity, which can be generated by rubbing your hand across the exposed metal parts an the board. To avoid this damage, always handle circuit boards by their edges, being careful to avoid contact with the exposed edge connectors and parts.
Following the instructions provided with the expansion board, set any configuration switches and jumpers on the expansion board.
Open the main system unit cabinet and set the configuration jumpers on the system motherboard to match the new hardware arrangement. You will be able to do this without removing the system motherboard from the main system unit
