f the Automation Server firmware is damaged, the Automation Server can be put in
DFU (Device Firmware Upgrade) mode to be able to communicate on the USB
device port.
After the reset operation and the initial boot process, the upgrade process can be
started, using the USB device port. It is also possible to retrieve debug information
from the device.
To reset the Automation Server
1. Start the Device Administrator. For more information, see StruxureWare
WebHelp.
2. On the Automation Server, press the Reset switch 3 times within 2 seconds.
3. Use a USB cable to connect the USB device port on the Automation Server
with a USB port on the PC.
4. Ensure that the Automation Server is displayed in the list and DFU mode is
displayed in the Device status column.
The Automation Server is now ready for the upgrade procedure. For more
information, see StruxureWare WebHelp.
Alternatively, the Device Administrator can now be used to fetch saved debug data.
For more information, see StruxureWare WebHelp.

electronics module is fitted. For the Automation Server, however, some
connections are made to the electronics module.
