      1| 57%
      2| 39%
      3| 12%
      4| 6%
      5| 47%
      6| 43%

System recovering after firmware update failure

If during the firmware update (through the web interface or through autoupdate mechanism based on DHCP) a failure occures (e.g. due to power cutoff) and the device does not operate (the 'Power' indicator is constantly solid red), use the following algorithm to recover the device:

• 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.
• Run the command to send a file to a remote host (the 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).
