Figure 16, FRNT v0 ring
In a ring configuration as FRNT v0, one, and only one, R/T200 switch must be configured to
be the network Focal Point. The Focal Point switch will then have the role as Redundancy
Manager, and thus be responsible for recovery when a connection between the switches is
broken. To set up a FRNT v0 configuration the following steps must be followed:
20. Define which Switch that shall be the network Focal Point.
21. Power up the switch and connect this to the network.
22. Assign an IP address for the configuration software. Ensure the address range is
within the same Subnet as your assigned IP address for your PC.
23. Press the ‘Scan for devices’ button. The Switches on the network will be listed.
24. Run the cursor over the listed Switch and left click the mouse.
25. A new configuration Window will open
26. If required; assign a new IP address and Subnet address for this Switch.
27. Press the ‘Set’ button to assign this IP address and Subnet settings to the Switch.
28. Tick the ‘Enable FRNT Ring’ and ‘Network focal point’ to set the Switch to be the
Focal Point and Bus Member to ensure the Switch configured to run within a
Redundant Ring.
29. Press the ‘Set’ button (all your changes performed will be set).
30. Press the ‘Restart’ button to re-configure the Switch. The Switch will run through the
start sequence. During this period communication to the Switch will be lost.
31. Connect the next Switch into the ring. (This must be connected from Port 8 to Port 7
in a clockwise manner on version 2.30 or older).
32. Press the ‘Scan for devices’ button. The second Switch will appear on the list.
33. Run the cursor over the second Switch and left click the mouse.
34. If required; assign a new IP address and Subnet address for this Switch.
35. Tick ‘Enable FRNT ring’ to ensure the Switch is configured to run within a Redundant
Ring.
36. Press the ‘Set’ button.
37. Press the ‘Restart’ button to re-configure the Switch. The Switch will run through the
start sequence. During this period communication to the Switch will be lost.
38. Continue connecting Switches in this manner until the ring has been completed
