3 - 14 ONline Ethernet 10BASE-FL Installation and Operation Guide
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 themselves, even if the ports were
previously disabled.
The redundancy status LEDs, located between the sets of port LEDs and the
port connectors on the 10BASE-FL Module, are:
❑ Off - When you disable redundancy (default setting).
❑ On - When you enable redundancy.
For information about the redundancy LEDs, refer to Table 3-5.
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.
Note: If you enable redundancy on one end of a link, you must
enable Remote Failure Signaling (RFS) at the other end. For
more information, refer to the next section, Enabling
Remote Failure Signaling.
