General Description
Chapter 1
Star Topology
The star structure consists of a number of modules connected to a central
switch. Modules can be added or removed without affecting the rest of the
network.
Figure 10 - Example of Star Topology
Linear Topology
The linear topology uses the embedded switching capability to form a daisy-
chain style network that has a beginning and an end. Linear topology simplifies
installation and reduces wiring and installation costs, but a break in the
network disconnects all modules downstream from the break. When this
topology is used, both Ethernet connections on the access box may be used. For
the network connection, use Link 1, Link 2, or both.

IMPORTANT
Modules without dual ports must include the 1783-ETAP module or be
connected at the end of the line.
