Implementing Total Backbone Fault Tolerance
You can add a backup ONline System Concentrator to provide total backbone fault tolerance and link redundancy for your backbone network. As shown in Figure
❑One port on the
❑The other port connects to the backup concentrator.
You must also have a direct connection between the two concentrators
