2 Put the SMT in command interpreter (CI) mode by entering 8 in Menu 24 – System 

Maintenance.

3 Enter 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 ZyXEL Device. Set the 

transfer mode to binary before starting data transfer.

5 Use the TFTP client (see the example below) to transfer files between the ZyXEL Device 

and the computer. The file name for 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 ZyXEL 
Device to the computer and “binary” to set binary transfer mode.

The following is an example TFTP command:

tftp [-i] host get rom-0 config.rom

where “i” specifies binary image transfer mode (use this mode when transferring binary files), 
“host” is the ZyXEL Device IP address, “get” transfers the file source on the ZyXEL Device 
(rom-0, name of the configuration file on the ZyXEL Device) to the file destination on the 
computer and renames it config.rom.

The following table describes some of the fields that you may see in GUI-based TFTP clients.

Table 93   General Commands for GUI-based TFTP Clients

Host

Enter the IP address of the ZyXEL Device. 192.168.1.1 is the ZyXEL Device’s default 

IP address when shipped.

Send/Fetch

Use “Send” to upload the file to the ZyXEL Device and “Fetch” to back up the file on 

your computer. 

Local File

Enter the path and name of the firmware file (*.bin extension) or configuration file 

(*.rom extension) on your computer.

Remote File

This is the filename on the ZyXEL Device. The filename for the firmware is “ras” and 

for the configuration file, is “rom-0”.

Binary

Transfer the file in binary mode.

Abort

Stop transfer of the file.
