PT-7728 User’s Manual Featured Functions
3-29
NOTE
The user does not need to assign the master to use Turbo Ring or Turbo Ring V2. If no master is
assigned, the Turbo Ring protocol will automatically assign master status to one of the PT series
Ethernet switches in the ring. The master is only used to determine which segment serves as the
backup path.
Ring 1/2—1st Ring Port Status

The Ports Status indicators show Forwarding for normal transmission, Blocking if this port is
connected to a backup path and the path is blocked, and Link down if there is no connection.
