Installing the Ethernet Connection
Connect a standard Category 5 network cable to the Ethernet RJ-45 port (and the other as
optional redundancy/backup). Connect the other end of the Category 5 network cables to
your IP network. The Ethernet connectors (labeled Ethernet 1 and Ethernet 2) are wired
according to
Figure 22 .
Note that for redundant operation it is recommended to connect each of the Ethernet
connectors to a different switch.
When assigning an IP address to the gateway using HTTP (under
