installation first.
5.2.1 Physical check
Verify the following causes for malfunctions or not functioning at all.
1. Is the SIMATIC powered up?
2. If used, is the SCALANCE switch powered up?
3. Are the network cables properly inserted into the LAN sockets of the devices?
This can be determined by evaluating the port LEDs of the devices. At least the
Link LED should be illuminated.
