Replacing the PLUG (C-PLUG or KEY-PLUG)
Danger from line voltage
After removing the housing cover, there is a risk of touching live parts in the area of the
connecting terminals of the power supply adapter.
Only authorized personnel is permitted to open the device and carry out any work on the
open device (e.g. connection and disconnection of cables, operating the reset button,
replacing the PLUG).
How it works
If a new C-PLUG or KEY-PLUG with a valid license is inserted in a SCALANCE W786, 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.
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.
