Deployment of a Standalone Device

The Ethernet ports on the SBC module can operate in pairs, called Ethernet Groups, to
provide Ethernet port 1+1 redundancy. In each pair, one port serves as the active Ethernet
port while the other as standby. When the active port fails, the device switches to the standby
Ethernet port. By default, the ports are provided in pairs, as shown in the figure below.
However, you can change the port assignment, including the option to assign only one port
to an Ethernet Group (i.e., no 1+1 redundancy scheme). For more information, refer to the
User's Manual.
It is important that the two ports in the Ethernet Group making up a pair are connected to
different switches (but in the same subnet). The figure below illustrates an example of
implementing Ethernet-port redundancy:
