NOTE
If you do not enable any of the EDS-405A/408A switches to be the Ring Master, the Turbo Ring
protocol will automatically choose the EDS-405A/408A with the smallest MAC address range to
be the Ring Master. If you accidentally enable more than one EDS-405A/408A to be the Ring
Master, these EDS-405A/408A switches will auto-negotiate to determine which one will be the
Ring Master.
