Resetting the device to default settings
To reset the device to default settings during operation, do the following:
1. Switch to display mode A.
Display mode A is active if the LEDs DM1 and DM2 are unlit.
If the DM1 and DM2 LEDs are lit or flashing, press the button briefly several times until the
LEDs are off.
If you do not press the button for longer than 1 minute, the device automatically changes to
display mode A.
2. Hold down the button for 12 seconds.
Note
If you release the button before the 12 seconds have elapsed, the operation is canceled.
3. Release the button after 12 seconds.
The device restarts with default settings.
8.3 Loading a firmware file via TFTP
Firmware
The firmware is signed and encrypted. This ensures that only firmware created by Siemens can
be downloaded to the device.
Procedure with Microsoft Windows
You can download new firmware to the device using TFTP. For this, the device cannot be
accessible via the Web User Interface (Web UI) or via the Command Line Interface (CLI). This may
be the case, for example, if a power failure has occurred during a firmware update.
When pressing the button, observe the information in the section "SELECT/SET button
(Page 27)".
Follow the steps below to load new firmware using TFTP:
1. Turn off the power to the device.
2. Press the SELECT/SET button and reconnect the power supply to the device while holding
down the button.
3. Hold down the button until the red alarm LED "A" starts to flash.
4. Release the button as long as the red alarm LED "A" is still flashing.
This time only lasts a few seconds.
The bootloader of the device waits in this status for a new firmware file that you can
download by TFTP.
