Enabling Port Redundancy
You can enable port redundancy in one of the following ways:
❑If you have network management, you can enable or disable main port redundancy between any two ports on the
❑If you do not have management, you can use the dip switches on the module to configure redundancy between ports 1 and 2 on the module or ports 3 and 4.
For example, when you enable redundancy:
1.Port 1 becomes the primary link and port 2 is the redundant link.
2.If the primary link (port 1) fails, the redundant link (port 2) is engaged automatically, thus preventing a network failure.
3.When you disable redundancy, each port works independently.
Note: Enabling port redundancy for two ports automatically enables the ports, even if the ports were previously disabled.

❑On - When you enable redundancy
To set redundancy between ports, use the following management command:
SET PORT {slot.port} MODE REDUNDANT {slot.port}
To turn off redundancy between ports, use the MODE NON_REDUNDANT option. Redundancy configurations are shown in Chapter 2, Designing and Expanding the Network.
