161 Chapter 18 Firmware and Configuration File Maintenance
2 Put the SMT in command interpreter (CI) mode by entering 8 in Menu 24 – System
Maintenance .
3 Enter the command “sys stdio 0” to disable the SMT timeout, so the TFTP transfer will
not be interrupted. Enter command “sys stdio 5” to restore the five-minute SMT timeout
(default) when the file transfer is complete.
4 Launch the TFTP client on your computer and connect to the ZyAIR. Set the transfer
mode to binary before starting data transfer.
5 Use the TFTP client (see the example below) to transfer files between the ZyAIR and the
computer. The file name for the firmware is “ras
” and the configuration file is “rom-0”
(rom-zero, not capital o).
Note that the telnet connection must be active and the SMT in CI mode before and during the
TFTP transfer. For details on TFTP commands (see following example), please consult the
documentation of your TFTP client program. For UNIX, use “get” to transfer from the ZyAIR
to the computer, “put” the other way around, and “binary” to set binary transfer mode.
18.4.5 Example: TFTP Command
The following is an example TFTP command:
TFTP [-i] host put firmware.bin ras
where “i” specifies binary image transfer mode (use this mode when transferring binary files),
“host” is the ZyAIR’s IP address, “put” transfers the file source on the computer (firmware.bin
– name of the firmware on the computer) to the file destination on the remote host (ras - name
of the firmware on the ZyAIR).
Commands that you may see in third party TFTP clients are listed earlier in this chapter.
18.4.6 Uploading Via Console Port
FTP or TFTP are the preferred methods for uploading firmware to your ZyAIR. However, in
the event of your network being down, uploading files is only possible with a direct
connection to your ZyAIR via the console port. Uploading files via the console port under
normal conditions is not recommended since FTP or TFTP is faster. Any serial
communications program should work fine; however, you must use the Xmodem protocol to
perform the download/upload.
18.4.7 Uploading Firmware File Via Console Port
Select 1 from Menu 24.7 – System Maintenance – Upload Firmware to display Menu
24.7.1 – System Maintenance – Upload System Firmware , then follow the instructions as
shown in the following screen.
