Introducing the NetStacker Hub
About Building a Stack
A stack of two or three NetStacker Hubs must consist of the
following:
❏
A
Base Hub
on the bottom of the stack
and
❏
One or two
Expansion Hubs
on top of the Base
Hub
The Base Hub, always located on the bottom of the stack, consists
of a Base Chassis containing one or two modules. The Base Chas-
sis provides built-in backplane timing for the stack.
The Expansion Hub consists of an Expansion Chassis containing
one or two modules.
Figure 2 shows a stack of three NetStacker Hubs, each containing
a 24-port, double-height RJ45B Module.
