connection failure occurs, the backup port will automatically become a
working port to recover.
The switch can be set in the ring master or slave mode. The ring master
negotiates and places commands to the other switches in the X-Ring group.
If there are two or more switches in the master mode, the software will
select the switch with lowest MAC address number as the ring master. The
X-Ring master mode is enabled using the X-Ring configuration interface.
The Ring Master can also be identified using the R.M. LED on the front of

The switch also supports coupling ring to connect two or more X-Ring
groups for redundant backup. The dual homing function is used to prevent a
connection lose between the X-Ring group and the upper level/core switch.
