Linking Distributed Segments

Hubs installed at various sites can be managed by a single EtherHub 1500 Agent when they are connected to the Agent via the FlexBus 1500 port connection. However, all hubs must be connected to the same segment at the central site. The segment setting for hubs at all other sites must be set to isolated. (Refer to the Segment Setting function in Chapter 4.) Hubs within the remote stacks can remain isolated or be connected to hubs within the same location using the STP daisy-chain or the ALT PORT connection. The maximum segment length using FlexBus 1500 cabling linking the distributed hubs is 100 meters.
