Downloading new firmware using TFTP without WBM and CLI
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. To do this, the device does not
need to be reachable either using Web Based Management (WBM) or using the Command
Line Interface (CLI). This can be the case if there was a power failure during a firmware
update.
When pressing the button, make sure you adhere to the instructions in the section "SET
button (Page 28)".
To load a new firmware via TFTP, follow these steps:
1.
Turn off the power to the device.
2.
Press and hold the SET button and reconnect the device to the power supply while holding
down the button.
3.
Hold down the button until the red fault LED "F" starts to flash after approximately 2 seconds
(500ms on/500ms off).
4.
Release the button as long as the red error LED is still flashing.
This time only lasts a few seconds.
The bootloader waits in this state for a new firmware file that you can download using
TFTP.
5.
Connect a PC to the device over the Ethernet interface.
6.
Assign an IP address to the device using DHCP or the SINEC PNI.
7.
In a Windows command prompt, go to the directory where the file with the new firmware is
located and use the following command:
tftp -i <IP address> put <firmware file>
.
Note
You can enable TFTP in Microsoft Windows as follows:
"Control Panel > Programs and Features > Turn Windows features on or off > TFTP Client".
Once the firmware has been transferred completely to the device and validated, the
device restarts. This process can take several minutes.
