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.
35.2.4 Example: TFTP Command
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 third party TFTP clients.
35.2.5 Backup Via Console Port
Note: The console port is internal and reserved for technician use only.
Back up configuration via console port by following the HyperTerminal procedure shown
next. Procedures using other serial communications programs should be similar.
