5.5 Replacing the PLUG (C-PLUG or KEY-PLUG)
NOTICE
Do not remove or insert a C-PLUG / KEY-PLUG during operation!
A PLUG may only be removed or inserted when the device is turned off.
The device checks whether or not a PLUG is inserted at one second intervals. If it is
detected that the PLUG was removed, there is a restart.
If a KEY-PLUG was inserted in the device, the device changes to a defined error state
following the restart. With SCALANCE W, the available wireless interfaces are
deactivated in this case.
If the device was configured at some time with a PLUG, the device can no longer be
used without this PLUG. To be able to use the device again, reset the device to the
factory settings.
NOTICE
Loss of water and dust protection
If the cover is not mounted correctly, the device is not water and dust proof.
