Isolating Each Hub

In this example, each hub in the stack is an independent

segment (i.e., isolated collision domain). Hubs 2 to 6 are not

connected to any of the 3 segments embedded in the FlexBus

3500 cable.

FIf the Fast EtherHub-12mi is isolated from the backplane (i.e., not
attached to any of the 3 segments), the stack can still be managed
with the out-of-band configuration program via the management
channel embedded in the FlexBus 3500 cable.
