43.9.1 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.
43.9.2 Filename Conventions
The configuration file (also known as the romfile or ROM) contains the Zyxel factory default configuration
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.
