At the back of the Switch to the left is the slot for the optional module, as shown in Figure 2-4 and Figure 2-5. This slot
should be covered with a faceplate that can be easily removed by loosening the screws and pulling off the plate.

After removing the faceplate, remove the DEM-420X or DEM-420CX4 optional module from its box. The front panel
should resemble the drawing represented here.
Take the module and gently slide it in to the available slot at the rear of the Switch until it reaches the back, as shown in the
following figure. At the back of the slot are two sets of plugs that must be connected to the module. Gently, but firmly push
in on the module to secure it to the Switch. The module should fit snugly into the corresponding receptors.
CAUTION: Before adding the optional module, make sure to disconnect all
power sources connected to the Switch. Failure to do so may result in an
electrical shock, which may cause damage, not only to the individual but to
the Switch as well.
