3-6 Setting Up Network Connections
Attaching the Stack to Multiple Segments
This example shows 3 independent Ethernet LANs in a stacked
system. Hubs 1 and 2 are attached to segment 1, while hubs 3
and 4 are attached to segment 2, and hubs 5 and 6 are attached
to segment 3.
This configuration serves to both balance the network load and
improve performance. Using three separate segments provides
300 Mbps of Ethernet bandwidth to the overall stack. Moreover,
using a segmented configuration serves to confine the effects of
heavy loading or network problems to a single segment.

Traffic in each segment is restricted to that segment and cannot pass
to another segment without a device such as a SmartExtender Module
or one of Accton’s Fast Ethernet Switches to link them.
