Fuses
The SCALANCE X000 IE switches 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.

If a fault develops, please send the device to your SIEMENS service center for repair. Repairs
