● Single NIC: The current NIC card works independently. If the current

NIC card is disconnected, the Device becomes offline.

● Fault Tolerance: Two NIC cards share one IP address. Normally only

one NIC card is working. When this card fails, the other NIC card will

start working automatically to ensure the network connection. The

Device is regarded as offline only when both NIC cards are

disconnected.

● Load Balance: Two NIC cards share one IP address and work at the

same time to share the network load averagely. When one NIC card

fails, the other card continues to work normally. The Device is

regarded as offline only when both NIC cards are disconnected.

The Device with single Ethernet port does not support this function.
