Mounting and wiring
4.8 LAN connections
LAN interface (X000/ X001)
The CX51x0 systems have two independent LAN interfaces. Both ports are able to operate at speeds of 10 /
100 / 1000 Mbit. The LEDs on the left­hand sides of the RJ45 sockets indicate the status of the LAN
connection. The upper LED indicates whether the port is connected to a network. If that case the LED is
yellow. The LED flashes if data traffic takes place on the port. The lower LED indicates the connection
speed. The LED is green if the speed is 10 or 100 Mbit. In 1000 Mbit mode (Gigabit) the LED is red.
