• Loading new firmware
If the "Load & Save" menu command of Web Based Management is unsuccessful, the
reset button can be used to load new firmware. This situation can occur if there is a
power outage during the normal firmware update. You will find further information in
the configuration manual in Downloading new firmware using TFTP without WBM and
CLI (Page 65).
• Resetting the device to the factory defaults
The device can be reset to the factory defaults during operation. You will find more
detailed information in the configuration manual in Resetting the device to factory
defaults (Page 63).

PLUG
The PLUG is available in the following variants:
• C-PLUG: The removable data storage medium only saves the configuration data of
the device.
• KEY-PLUG: In addition to the configuration data, the removable data storage medium
contains a license with which special functions are enabled, e.g. iFeatures.
You will find the article numbers under Accessories (Page 22).
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.
