NOTE
You must enable the Turbo Ring function first before using the DIP
switch to active the Master and Coupler functions.
NOTE
If you do not enable any of the EDS-505A/508A switches to be the
Ring Master, the Turbo Ring protocol will automatically choose the
EDS-505A/508A with the smallest MAC address range to be the
Ring Master. If you accidentally enable more than one
EDS-505A/508A to be the Ring Master, these EDS-505A/508A
switches will auto-negotiate to determine which one will be the
Ring Master.
LED Indicators

described in the following table.
