Chapter 3 Configuring Platform Parameters
Input GbE Ports Configuration
• Upon redundancy switch, automatically the configured backup port is activated. If the
backup port fails, a redundancy switch is performed to return to the Primary. If the
primary port is still faulty, the redundancy mechanism, re-checks the last active port for a
momentary failure. If it is still faulty, the redundancy switch reverts to the primary and
keeps checking in increased intervals the configured backup port, until detecting an
active port.
• Redundancy switches are written in the alarm log. To view the history of the port
redundancy switches, select Monitoring > Logs > Alarm Log and click View Log.
