Mounting the Modules
Before inserting the modules, read their respective chapters to make sure that there are no jumpers that need to be set in order to carry out the desired function(s). The modules are located, as illustrated in fig.5.1, by aligning the front plate screw with the keyhole slot (fig.5.2C); the key at the bottom of the front plate (fig.5.2D) with the slot in the bottom of the housing; and the multi connector (fig.5.2E) with the socket mounted on the mother board. The module is then gently pushed into place by putting pressure on the top of the circuit board. If it does not slot easily into place do not attempt to force it. Check that it is properly aligned and try again. When the modules are inserted, and properly seated in their connectors, tighten their front plate screws.
