Universal Network Terminal TAU-32M.IP 295
APPENDIX B. ALTERNATIVE FIRMWARE UPDATE METHOD
When you cannot update the firmware via web interface or CLI (telnet, SSH), you may use an alternative
firmware update method via console (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
window:
