5.1 Module Stacking Order
Although you are not actually installing the
modules yet, it is important to become familiar with
the five chassis positions available for modules in
the Multiserver unit. These are identified from
bottom to top as module locations A through E (see
Figure 5-1). The possible hardware-configuration
combinations are numerous. Regardless of the
combination you choose, the Communications
Control Module (CCM) must always be in module
location A. The optional NMS module is always
installed directly below the CCM. The rest of the
modules should be installed in the following order,
from bottom to top:
• 6-channel CEM
• 12-channel CEM
• Voice/fax module
• RLB module
• 56K CSU/DSU module
Stacking is done from bottom to top without
skipping a module location. For example, if you
have three modules (a CCM and two optional
modules), the modules should be stacked in
module locations A through C with locations D
and E left open. If there are four modules, module
location E will be left unused.
