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.
NOTICE
Loss of water and dust protection
If the cover is not mounted correctly, the device is not water and dust proof.
How it works
If a new C-PLUG or KEY-PLUG with a valid license is inserted in a SCALANCE
W778/W738, the configuration stored locally on the device is saved on the PLUG.
If an incorrect PLUG, for example from another product or a damaged plug is inserted, the
device signals an error with the red LED. The user then has the choice of either removing
the PLUG again or selecting the option to reformat the PLUG.
In terms of the PLUG, the WLAN devices work in two modes:
● Without PLUG
The device stores the configuration in internal memory. This mode is active when no
PLUG is inserted.
● With PLUG
The configuration stored on the PLUG is displayed over the user interfaces. If changes
are made to the configuration, the device stores the configuration directly on the PLUG
and in the internal memory. This mode is active as soon as a PLUG is inserted. As soon
as the device is started with a PLUG inserted, the SCALANCE W700 starts up with the
configuration data on the PLUG.
Position
The PLUG slot is on the top of the device housing under a cover, see Reset key (Page 25).
