The “RM” DIP switch of this model is used to configure the switch as Ring Master (ON), or slave
(OFF). Only one switch may assume the role of Ring Master. The Ring Master has the right to
negotiate and send commands to other switches in the ring group. When the switch is configured
to be the redundant Ring Master, the ring configuration interface will display a message
indicating that this switch is the Ring Master.
The system also supports a coupled ring function which allows two or more redundant ring
groups to be connected together to provide a redundant backup solution.
Enable Super Ring
: You can enable the redundant ring function by checking this option.
Note
: You must enable the redundant ring function before connecting any backup path to
prevent the inadvertent generation of message loops.
Working Ports
: You can assign 2 ports as member ports here. One port will be the working port,
the other will be the backup port (the Ring Master will automatically decide which port functions
as the working port, and which one is the backup port).
Once you finish your configuration, click on
Apply
to apply your settings. Do not complete the
ring until you have already setup all the ring switches, or message loops may develop
immediately.
IMPORTANT
: If you enable the redundant ring function (Super Ring), you must disable RSTP.
The redundant ring function and the RSTP function cannot both be enabled at the same time.
