Redundancy
The FT-1105A / FT-1205A provide less than 10 ms link redundancy
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 Primary-Port is active at a time, the Backup-Port is
blocked.
• While Primary-Port link fail occur, the traffic swap to
Backup-Port automatically.
• Once the Primary-Port status back to link up, the traffic
swap from Backup-Port to Primary-Port.
