Reconfiguring a Circuit 7-11
Redundancy
To change a port’s designation from primary to backup, or vice versa:
1. On the altered Chassis View, click on the port whose designation you wish to
change.
2. Select Primary or Backup, as appropriate, to change the port’s designation.
Note that changing a port’s designation as primary or backup will not change its
current active or inactive status; if you wish to activate a port you have just
changed from backup to primary, or deactivate a port you have just changed from
primary to backup, you must also use the Activate and Deactivate commands
described above.
Resetting a Circuit
Resetting a circuit changes the status of the circuit to disabled, deletes all entries
in the Polling Address list, and clears all port designations. You can reset circuits
individually or collectively.
To reset an individual circuit:
1. Use the drop-down list to display the appropriate circuit in the Current Circuit
text box; note that the current status of the selected circuit (enabled or
disabled) is displayed just below the Current Circuit text box.
2. Click on Configure, and select Reset. This will clear all redundancy settings
for the selected circuit, and restore it to its original undefined and disabled
status.
To reset all circuits at once:
1. Click Reset. A warning window will appear ( Figure 7-8 ), asking you to confirm
your selection.

NOTE
Any backup port which has been part of an enabled circuit will remain disabled by
management until you turn it back on at the Chassis View window (in Logical mode), so
that accidental data loops do not occur. Be sure to disconnect any redundant network
links before re-enabling ports.
