Functional Modules
The Functional Modules (cards) perform the various audio, video, and data
processing functions for the MGC unit. Both the MGC-100 and the MGC-50
use the same functional modules.
The MGC-100 unit houses up to sixteen Functional Modules, which can
occupy slots 1 through 16.
The MGC-50 unit houses up to eight Functional Modules, which can occupy
slots 1 through 8.
The LED’s on the front of each Functional Module indicate the status of
operation and whether it is functioning properly. Functional Modules are
installed via the front panel of the MGC unit. A connector at the rear of each
function al module connects the module to the backplane. Any module can be
inserted into any slot. All Functional Modules are front-removable and hot
swappable.
Table 4-4 lists the available Functional Modules.
