1420 Wireless Gateway
Figure 2-1. Redundant Ethernet
Network Topology
2-10
If the 1420 Wireless Gateway has been ordered with a redundant network
interface, the network setup page (Setup>Internet Protocol>Address) will
display a secondary interface as shown below.
The second network interface allows the 1420 to be accessed with two
separate network addresses. The redundant interfaces provide the 1420 with
a degree of fault tolerance to network failures. The network topology shown in
Figure 2-1 is supported.
(Subnet 192.168.1.XX)
NOTE
The subnet numbers listed in the diagram are an example. Any valid network
subnets are acceptable.
If you will be using the redundant ethernet feature, you may select to have the
device obtain an IP address via DHCP or be statically assigned an IP for the
secondary interface. Contact your network administrator if you are not sure
which selection is appropriate.
