W&T Firmware update of the Com-Server
21.3 Network firmware update under UNIX
Required is a computer with a network connection and a TCP/IP
stack that provides Telnet and TFTP network protocols. When
updating with TFTP protocol the firmware is split into 6 files
that are send to the Com-Server one after the other.
1. Start the remote configuration tool of the Com-Server over
Telnet
telnet [IP address] 1111
In the SETUP: menu select System r Flash Update r Net
Update and confirm with y. The Com-Server closes the
Telnet connection. The green Status LED indicates that
the Com-Server is in update mode.
2. Now use the TFTP command to send the first file in
binary mode to the Com-Server. While the data are being
sent over the network the Status LED will be on. Then the
Com-Server goes into programming mode and the Error
LED comes on. This process may take several seconds.
Wait until the Error LED goes off and the Status LED
comes on again. Repeat this process for all six files.
3. The Com-Server recognizes when all files have been sent
and independently does a restart. If the green Status LED
comes on again after all the files have been sent, repeat
Step 2 again in full. Sending a file twice does not result
in an update error. The Com-Server waits until all the
necessary files have been sent.
4. Check the configuration menu of the Com-Server to make
sure it took the new operating software. The version
number of the new firmware should now be seen in the
INFO Com-Server r SOFTW Date/Rev menu.
If the previous version is still displayed, then one or more
of the files with the new operating software is corrupted.
