38.7.2 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.
38.7.2.1 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.
Be sure to upload the correct model firmware as uploading the wrong
model firmware may damage your device.
38.7.3 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.
