CHAPTER 5: Module Installation

5.2 Module-Location Switch Settings
Each expansion module has a module-location
switch group S1 that informs the software of its
location in the Multiserver unit (see Figure 5-2).
There are two exceptions: the CCM, which is always
in module location A, and the NMS module, which
is always located below the CCM. The physical
location of the switch is unique to each module.
Switch group S1 consists of four positions
numbered 1 through 4. Before setting S1, first
determine the location where the module is to be
installed. Then, set the switches to match the
intended module location. For example, if the
intended module location is C, set switch 2 on,
and the other three off. To set a switch on, use
a ballpoint pen or similar pointed tool and push
the switch down.
NOTE: Switch group S1 settings for module
locations B through E are different for each
module location (see Figure 5-2). Be sure
that each switch reflects the correct setting
for the intended module location. Also, take
care that only one switch is on (down) and
that the remaining three switches are off
(up).
