Setting the Switch Group
To set a switch to on, use a ballpoint pen or similar pointed tool and push the
switch down. Take care that only one switch is on (down) and that the remaining
three switches are off (up) (see Figure 10-2 below).
Notice that each switch can represent either a numeric LIM or an alpha LIM,
depending on the expansion module. For instance, setting the left-most switch
to on would assign LIM 1 to a data module; the same switch settings on a voice
module would assign LIM B.
LIM assignments are used by the software when configuring the modules.

Stacking Connectors
Stacking connectors act as a bus allowing data to be transferred between the
expansion modules and the base card; they must be firmly seated within their
mating connectors.
