APPENDIX B. ALTERNATIVE FIRMWARE UPDATE METHOD
When you cannot update the firmware via web interface or the console (telnet, RS-232), you may use an
alternative firmware update method via RS-232.
To update the device firmware, you will need the following programs:
—
Terminal program (for example: TERATERM);
—
TFTP server program.
Firmware update procedure:
1.
Connect to Ethernet port of the device.
2.
Connect PC console port to the device console port using a crossed cable.
3.
Run the terminal application.
4.
Configure data rate: 115200, data format: 8bit w/o parity, 1 stop bit, w/o flow control.
5.
Run TFTP server program and specify the path to 'chagall' folder. In this folder, create '300' subfolder,
and place firmware.elf, initrd.300, zImage.300 in it (computer that runs TFTP server and the device should
be located in a single network).
6.
Turn the device on and stop the startup sequence by entering
stop
command in the terminal program
