EDS-518A Series User’s Manual Featured Functions
3-20
Decide appropriate coupling ports in each switch and link them together. Next, assign one switch
(e.g., Switch A) as coupler and set the proper coupling control port with another switch (e.g.,
Switch B) in the same Turbo Ring, and then connect them. The Coupler switch (e.g., Switch A)
will monitor switch B through the coupling control port to decide if the coupling port’s backup
path should be recovered or not.
ATTENTION
The user only needs to enable the “Ring Coupling” function on one EDS-518A (not on the
opposing EDS-518A or an adjacent EDS-518A). The Redundant Port, Coupling Port, and
Coupling Control Port must all be assigned to different ports.
NOTE
Ring Coupling and Ring Master do not need to be set up on the same EDS-518A.
Configuring Turbo Ring
Use the Communication Redundancy page to configure Turbo Ring.
Now Active
This field shows which communication protocol is in use: Turbo Ring, RSTP, or neither.
Master/Slave
This field appears only when Turbo Ring mode is selected for Redundancy Protocol. It indicates if
this EDS-518A is or is not the Master of the Turbo Ring.
NOTE
The user does not need to set the master to use Turbo Ring, only to assign which segment serves
as the backup path.
The master will be determined automatically if the user does not set a dedicated master for the
Turbo Ring.
