Fiber Expansion media bay module

The Fiber Expansion media bay module (FEM) connects a maximum of six Norstar expansion
modules to the Business Communications Manager system. These connections provide a quick
way to upgrade a Norstar system to a Business Communications Manager system.
The front bezel of the FEM has six connectors. These connections are made using fiber cables
between the FEM module and the Norstar expansion modules. Beside each connector, an LED
lights when the fiber port is enabled.
The module has port status LEDs beside each port, as well as the usual power and status LEDs.
Figure 22 shows the front of the FEM module. Each port that is turned on consumes one DS30
bus.
