Both Class B and Class X perform all required monitoring of the health of the network. Class X wiring will
automatically 'heal' the ring when a break or other failure is encountered. The failure is reported via
SNMP (Simple Network Management Protocol) to the Management Station.
The fiber switch obtains its power from a 24V UL/ULC Listed for Fire Application, Regulated Power
Supply. It provides connectors for the fiber cable and four RJ45 100BaseT network connections.
In Class X, the fiber switch that is connected to the primary Management Station is designated as the ring
master. There is no difference in installation, configuration, and operation of single mode or multimode
fiber optic switches except the type of fiber used.
