8.8.3. Redundant configuration of switching hubs
In the connection example below, the LAN Link A and B connectors of each VX-3000F are individually connected
to different switching hubs. By using switching hubs with failure status output function, if any one of switching
hubs fails or the main line breaks, such a failure can be detected.
Notes
• Up to 7-level cascade is allowed for switching hub connections.
• After connection completion, reactivate the VX-3000F units.
• The "External failure input" function needs be assigned to the unit's control input terminal to which the switching
hub's failure status output is connected. (For details, see the separate Setting Software Instructions, "EVENT
SETTINGS" and "Failure Pattern Settings.")
Note: Contact your TOA dealer for more information on switching hubs.
