“Turbo Ring” rings with an odd number of EDS-516A units
Master
Segment N+1
If there are 2N+1 EDS-516A units (an odd
number) in the “Turbo Ring” ring, with
EDS-516A units and segments labeled
counterclockwise, then segment N+1 will serve
as the backup path.
For the example shown here, N=1, so that
N+1=2.
Determining the Redundant Path of a “Turbo Ring V2” Ring
Master
For a “Turbo Ring V2” ring, the backup
segment is the segment connected to the 2nd
redundant port on the master.
See Configuring “Turbo Ring V2” in the
Configuring “Turbo Ring” and “Turbo Ring
V2” section below.
Ring Coupling Configuration
For some systems, it may not be convenient to connect all devices in the system to create one BIG
redundant ring, since some devices could be located in a remote area. For these systems, “Ring
Coupling” can be used to separate the devices into different smaller redundant rings, but in such a
way that they can still communicate with each other.
ATTENTION
In a VLAN environment, the user must set “Redundant Port,” “Coupling Port,” and “Coupling
Control Port” to join all VLANs, since these ports act as the “backbone” to transmit all packets
of different VLANs to different EDS-516A units.
