Fuses
Some of the Industrial Ethernet switches of the SCALANCE X-100 product line have a
resettable fuse / PTC. If the fuse blows, all LEDs are off although the power supply is
correctly connected. In this case, disconnect the device from the power supply for
approximately 30 minutes before you turn it on again.
Link display on the optical ports
The SCALNCE XC106-2 supports “far end fault” on the optical ports. This function is,
however, not used for the corresponding link display. If only the receive direction is plugged
in, a “far end fault” is detected and no data is forwarded. The port LED is already lit.
Device defective
If a fault develops, send the device to your SIEMENS service center for repair. Repairs on-
site are not possible.
Restoring the factory settings
Follow the steps below to reset the device parameters to the factory settings:
Note
When you reset the device parameters, all previously changed settings are lost.
1.
Turn off the power to the device.
2.
Press the “SET" button for example with a screwdriver and reconnect the power to the
device while holding down the button.
3.
Hold down the button until the red fault LED "F" stops flashing after approximately 40
seconds and is permanently lit.
4.
Release the button and wait until the fault LED "F" goes off.
The device starts automatically with the factory settings.
