SET button
1.5 SET button
With a SCALANCE M-800, the SET button is on the front of the housing beside the LED
display.
The SET button has the following functions:
● Restart
Hold down the button for longer than 3 seconds to run a restart.
● Loading new firmware
If the normal procedure with the "Load & Save" menu of Web Based Management does
not work, 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.
– Hold down the button until the red fault LED (F) starts to flash after approximately 3
seconds.
– Now release the button. The bootloader waits in this status for a new firmware file that
you can download using TFTP.
You will find more information in the section "Service and Maintenance" in the
SCALANCE M-800 Web Based Management configuration manual.

C-PLUG and KEY-PLUG
How it works
NOTICE
Do not remove or insert a C-PLUG / KEY-PLUG during operation!
1.6 C-PLUG and KEY-PLUG
The C-PLUG or KEY-PLUG is used to transfer the configuration of the old device to the new
device when a device is replaced.
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.
When the new device starts up with the PLUG, it then continues automatically with exactly
the same configuration as the old device. One exception to this can be the IP configuration if
it is set over DHCP and the DHCP server has not been reconfigured accordingly.
A reconfiguration is necessary if you use functions based on MAC addresses.
If an incorrect PLUG, for example from another product or a damaged PLUG is inserted, the
device signals an error with the "F" LED.
You can either remove the PLUG again or select the option to reformat the PLUG.
In terms of the PLUG, 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 in WBM in "Information > PLUG". 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 device starts up with the
configuration data on the PLUG.
