2.1.7 Redundancy Overview

The Industrial Gigabit Ethernet Switch provides rapid fiber redundancy of link for highly critical Ethernet applications. The
redundant-mode supports auto-recover function. If the destination port of a packet is link down, it forwards the packet to
the other port of the backup pair. The following figure shows the redundant function.
Link status auto detect and redundant on Dual ports with same connector type.
Only when Primary-Port is active, the Backup-Port is blocked.
When Primary-Port link failure occurs, the traffic will swap to Backup-Port automatically.
Once the Primary-Port status is back to link up, the traffic will swap from Backup-Port to Primary-Port.
