ZyNOS (ZyXEL Network Operating System sometimes referred to as the “ras” file) 
is the system firmware and has a “bin” filename extension. 

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.

Launch the FTP client on your computer.

Enter open, followed by a space and the IP address of your Switch.  

Press [ENTER] when prompted for a username.

Enter your password as requested (the default is “1234”).

Enter bin to set transfer mode to binary.
