Chapter 4 Configure a Supervisor on a Device-level Ring Network
Construct the Physical
Network The first thing you must do to create a new DLR network is physically connect
all necessary devices to the network. However, leave at least one connection
unmade, that is, temporarily omit the physical connection between two nodes on
the ring, as the factory default settings of DLR devices are set to operate in linear/
star mode or as ring nodes on existing DLR networks.
This figure shows an example of a new DLR network with one physical
connection left open.
