Redundancy Overview
The Industrial Gigabit PoE+ Switch provides rapid fiber redundancy of link for
highly critical Ethernet applications; the redundant mode supports auto-recover
function. If the link of the destination port of a packet is down, it will forward
the packet to the other port of the backup pair. The following figure shows the
redundant functions.

Traffic is changed from Primary Port to Backup Port
This mode allows the Industrial Gigabit PoE+
Switch to use 6 ports.
This mode allows one of the two SFP ports to
be redundant while the other 5 ports are in
operation.
