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.
