4.3
Possible sources of problems and how to deal with them
Fuses
Note
Some of the Industrial Ethernet switches of the SCALANCE X-100 product line have a
resettable fuse / PTC. If the fuse triggers (all LEDs are off despite correctly applied power
supply), the device should be disconnected from the power supply for approximately 30
minutes before turning it on again.
Link display on the optical ports
The Industrial Ethernet switches SCALANCE X104-2, SCALANCE X106-1 and
SCALANCE X112-2 support "far-end fault" on the optical ports but do not use this for the
corresponding link display. This means that if there is only a cable connected in the receive
direction on the optical port, a far-end fault is detected and no data is forwarded. The Link
LED is already lit.
LED display when voltage drops
If both of the power supplies drop below approximately 14 V, this reduced voltage is
indicated by the red fault LED. The L LEDs go off.
If a fault develops, please send the device to your SIEMENS service center for repair.
Repairs on-site are not possible.
