2.1.7 Redundancy Overview
The Industrial Gigabit Media Converter 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.
Figure 2-5: Redundancy Behavior Topology
y
Link status auto detect and redundant on Dual ports with same connector type.
y
Only Primary-Port is active at a time, the Backup-Port is blocked.
y
When Primary-Port link failure occurs, the traffic will swap to Backup-Port automatically.
y
Once the Primary-Port status is back to link up, the traffic will swap from Backup-Port to Primary-Port.
Once enable fiber redundant function, port 1 will be “Primary Port” and port 2 will be
“Backup Port” .
