1. Select any two ports as redundant ports.
2. Connect the redundant ports to form the Turbo Ring
The user does not need to configure any of the switches as the master to use Turbo Ring or Turbo Ring V2. If
none of the switches in the ring is configured as the master, then the protocol will automatically assign master
status to one of the switches. In fact, the master is only used to identify which segment in the redundant ring
acts as the backup path. In the following subsections, we explain how the redundant path is selected for rings
configured for Turbo Ring, and Turbo Ring V2.
Determining the Redundant Path of a “Turbo Ring” Ring
In this case, the redundant segment (i.e., the segment that will be blocked during normal operation) is
determined by the number of EDS units that make up the ring, and where the ring master is located.
When the number of EDS-P510 units in the Turbo Ring is even.

If there are 2N EDS units (an even number) in the “Turbo
Ring” ring, then the backup segment is one of the two
segments connected to the (N+1)st EDS (i.e., the EDS unit
directly opposite the master).
When the number of EDS-P510 units in the Turbo Ring is odd.

If there are 2N+1 EDS units (an odd number) in the “Turbo
Ring” ring, with EDS 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.
