Redundant Twisted Pair Backbone

You can implement twisted pair link redundancy between ONline System Concentrators using network management.

Figure 2-5 shows an example of a redundant configuration between concentrators using 24-Port Modules.

Figure 2-5. Redundant Twisted Pair Configuration Using 24-Port Modules

To set link redundancy between two 24-Port Modules (refer to Figure 2-5):

1.Connect one port on the 24-Port Module installed in the concentrator on the left to a corresponding port on the 24-Port Module installed in the concentrator on the right.

2.Connect the second port on the 24-Port Module installed in the concentrator on the left to a corresponding port on the 24-Port Module installed in the concentrator on the right.

Note: Use a crossover adapter between each link because the links are designed to be connected to station ports, not to other lobe ports.
