During Normal Operation

You can use the Configure button any time you want the system to perform a diagnostic test. However, when testing begins, the system leaves normal operation. If no problem is encountered by diagnostics, the system automatically returns to normal operation.

Multi-Segment Architecture

The EtherHub 1500 system supports multi-segment configuration through the FlexBus 1500 cabling. Three Ethernet segments are embedded in the hub’s FlexBus 1500 port providing 3 isolated segments (i.e., separate collision domains). You can choose to attach a hub to a segment, or to leave it isolated except for the management channel. Nodes attached to a specific segment (e.g., Segment 1) can only communicate with nodes attached to the same segment. This type of architecture makes the system more flexible, provides better traffic load sharing and data protection, and improves network bandwidth utilization.

ΦNote that the EtherHub-16mi+cannot be physically isolated.

To make this architecture work for your system, plan your network setup well. Form a common domain for devices that need to communicate with each other by attaching them to the same segment. This way you can arrange network resources to balance traffic and thereby increase overall network efficiency.

To combine the segments into an interconnected network (while at the same time retaining the higher effective bandwidth and segment integrity provided by the multi-segment architecture), attach each segment to a bridge or similar interconnection device, such as Accton’s Secure Backbone Hub (EtherHub-SBH) or the Smart Ethernet Switching Hub (SwitcHub-8s).
