Parameter Description
Network Mode
Figure 5-180 TCP/IP
Table 5-50 TCP/IP parameters
● 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.
