Siemens CP 1625 Operating Instructions Manual page 11

RJ45 sockets
The connection of the CP 1625 to the LAN (Local Area Network) is made via one of the two
RJ45 sockets on the front panel of the communications processor.
The two sockets lead to the integrated real-time switch.
Note
Short-circuiting the LAN ports
If you accidentally short-circuit the two LAN ports of the communications processor, this
leads to a malfunction of the network and the communications processor.
To restore the full scope of functions, you may need to reset the communications processor
or the Software Controller.
LEDs of the RJ45 sockets
Two LEDs can be found in the frame of each RJ45 socket.
● The green LED lights up when a connection is established (Link LED).
● The yellow LED lights up during sending and receiving (Activity LED).
