Fault-Tolerant Configurations
This section contains descriptions of the redundancy features built into the ONline
This section contains the following topics:
❑Configuring Ports for Fault Tolerance
❑Implementing Backbone Cable Plant Fault Tolerance
❑Implementing Total Backbone Fault Tolerance
Configuring Ports for Fault Tolerance
You can configure ports 1 through 4 on the
❑Normal Configuration - Ports 1 through 4 operate as independent cable ports.
❑Standard Redundant Configuration - In this configuration:
–Port 1 acts as the primary port and port 2 as the backup for 1.
–Port 3 acts as the primary port and port 4 as the backup for 3.
❑Flexible Redundant Configuration - You can arbitrarily assign primary and backup ports to any pair of ports. You can configure this mode only through a network management module.
❑Normal and Redundant Configuration - You can enable redundancy between one set of ports and configure the remaining two ports to operate as independent ports.
