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
