How to Use EDS-405
Star-Wired Topology
EDS-405 can also be used to form a star-wired topology, as shown below. Since
ports 4 and 5 of EDS-405 are programmed to recognize the Turbo Ring topology
immediately, when using a star-wired topology, you might have to wait for the
EDS-405s to negotiate and recognize that port 4 and port 5 are not being used to
form a Turbo Ring topology.

NOTE
EDS-405 is a switch with plug-and-play ring redundancy. Ports 4
and 5 are designated as the ports that should be used to form a
Turbo Ring Topology. However, you can use port 4 or port 5 for
other purposes. For example, such as when EDS-405 is
connected to a star-wired topology. In this case, you might need
to wait several seconds before data transmission begins, since
EDS-405 needs to negotiate and recognize that port 4 and port 5
are not being used to form a Turbo Ring topology while it is
booting up.
