Mounting and wiring
3.8 LAN connections
LAN interface (X000/ X001)
The CX9020 systems have two switched LAN interfaces. Both ports are able to operate at speeds of 10 /
100 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. The LED flashes if data traffic takes
place on the port (Link /Activity). The lower LED indicates the connection speed. The LED is off if the speed
is 10 Mbit. In 100 Mbit mode the LED is green.

Note
Dependence of the ports
Both ports are dependent of each other. In contrast to the CX50x0 and CX20x0 systems,
one switch is integrated. For a line topology no further switch is required.
