5.2
Connecting to LAN
The device provides up to four 10/100/1000Base-T (Gigabit Ethernet) RJ-45 ports and up to
eight 10/100Base-TX (Fast Ethernet) RJ-45 ports for connection to the LAN.
These LAN ports operate in pairs (groups) to provide LAN port 1+1 redundancy. In each
pair, one port serves as the active LAN port while the other as standby. When the active
port fails, the device switches to the standby LAN port.
The figure below shows the LAN port-pair groups and the name of the ports and groups as
displayed in the Web interface for configuring the port groups and assigning them to IP
network interfaces (refer to the User's Manual for more information):

These ports support half- and full-duplex modes, auto-negotiation, and straight or crossover
cable detection.
