Accton Technology 1500 manual Each Hub is Isolated, Stacked Hubs Not Linked to a Segment

EtherHub 1500 System User’s Guide

Each Hub is Isolated

In this example, each hub in the stack is an independent segment (isolated). Hubs 2 to 10 are not connected to any of the 3 segments embedded in the FlexBus 1500 cabling; while the EtherHub-16mi+(EtherHub 1500 Agent), though attached to Segment 1, is functionally isolated.

Figure 5.4 Stacked Hubs Not Linked to a Segment

ΦThe EtherHub-16mi+is designed to be attached to one of the 3 segments. In this example, the EtherHub-16mi + is functionally isolated though attached to a segment. Traffic in each segment is restricted to that segment and cannot pass to another segment without a device such as Accton’s Secure Backbone Hub (EtherHub- SBH) or Smart Ethernet Switching Hub (SwitcHub-8s) to link them.
