ZyNOS (ZyXEL Network Operating System sometimes referred to as the “ras” file) is the
system firmware and has a “bin” filename extension.
24.8.1.1 Example FTP Commands
ftp> put firmware.bin ras
This is a sample FTP session showing the transfer of the computer file "firmware.bin" to the
switch .
ftp> get config config.cfg
This is a sample FTP session saving the current configuration to a file called “config.cfg” on
your computer.
If your (T)FTP client does not allow you to have a destination filename different than the
source, you will need to rename them as the switch only recognizes “config” and “ras”. Be
sure you keep unaltered copies of both files for later use.
1 Be sure to upload the correct model firmware as uploading the wrong model
firmware may damage your device.
24.8.2 FTP Command Line Procedure
1 Launch the FTP client on your computer.
2 Enter “open”, followed by a space and the IP address of your switch.
3 Press [ENTER] when prompted for a username.
4 Enter your password as requested (the default is “1234”).
5 Enter “bin” to set transfer mode to binary.
6 Use “put” to transfer files from the computer to the switch, for example, “put
firmware.bin ras” transfers the firmware on your computer (firmware.bin) to the switch
and renames it “ras”. Similarly, “put config.cfg config” transfers the configuration file
on your computer (config.cfg) to the switch and renames it “config”. Likewise “get
config config.cfg” transfers the configuration file on the switch to your computer and
renames it “config.cfg.” See earlier in this chapter for more information on filename
conventions.
7 Enter “quit” to exit the ftp prompt.
