Inserting and removing 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 present at one second intervals. If it is
detected that the PLUG was removed, there is a restart. If a valid KEY-PLUG was inserted
in the device, the device changes to a defined error state following the restart. With
SCALANCE M, the wireless interface is deactivated in this case.
Inserting the PLUG
1. Turn off the power to the device.
2. The housing of the PLUG has a protruding ridge on the long side. The slot has a groove
at this position.
Insert the PLUG correctly oriented into the slot.
