24.8  FTP Command Line
This section shows some examples of uploading to or downloading files from the Switch using 
FTP commands. First, understand the filename conventions.
24.8.1  Filename Conventions 
The configuration file (also known as the romfile or ROM) contains the factory default 
settings in the screens such as password, Switch setup, IP Setup, and so on. Once you have 
customized the Switch’s settings, they can be saved back to your computer under a filename of 
your choosing.
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”).
