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 state 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.
