System recovering after firmware update failure

...

• Unpack the archive with firmware file.
• Connect PC to the device port. Set the following subnet mask on the network interface: 192.168.1.0/24.
• Run the TFTP client on the PC (for Windows, it is recommended to use the Tftpd32), specify 192.168.1.6 as the remote host address, and select the linux.bin file from the unpacked software archive for transfer.
• Launch the command to transmit the file to remote host (Put command). The process of file transmission will be launched.
• If the transmission has started, please, wait for finishing. The device will write the firmware to its memory and launch the system automatically. The time of writing takes approximately 8 minutes. If the process is completed successfully, «Power» indicator will be green or orange. The configuration of the device before failure is saved. If you can not connect the device, reset it to factory settings.
• If the process has not started, make sure that the network settings of PC are correct and try again. If it does not work, sent the device to maintanence service or proceed recovery using the connection via COM port through a special adapter (if available).

Appendix A. Launch user script when starting the system

Sometimes you need the device to implement certain actions when starting, which cannot be implemented through settings in configuration file. In this case you may configure a user script through a configuration file that will be launched when the system starting. You may set any needed commands sequence.

...

1. Launch from HTTP server
   To launch a script from HTTP server, enter the entire path to the file in HTTP-URL format to URL parameter: 
   URL: " http://192.168.0.250/user-script/script.sh "
   In this case, after the device started, file script.sh, which is kept in the catalogue having 192.168.0.250 address, will be automatically loaded via HTTP from the defined server. Then it will be launched.
2. Launch from TFTP server
   To launch a script from TFTP server, enter the entire path to the file in TFTP-URL format to URL parameter: 
   URL: " tftp://192.168.0.250/user-script/script.sh "
   In this case, after the device started, file script.sh, which is kept in the catalogue having 192.168.0.250 address, will be automatically loaded via TFTP from the defined server. Then it will be launched.
3. Local script launch
   Due to the peculiar properties of the file system, a local script should be stored in /etc/config catalogue as the content of the catalogue is saved after device reload. You may create script in /etc/config catalogue through vi editor or load it from TFTP server using tftp –glsh <TFTP-server address> command. After creating a script, you should set rights for launching using the following command:
   chmod 777 /etc/config/user.sh
   In configuration file, URL for local script launching should be set as follows: 
   URL: " File://etc/config/user.sh " 
   
   A user script should start from the #!/bin/sh directive.
