CHAPTER 40

Firmware and Configuration File

Maintenance

This chapter tells you how to backup and restore your configuration file as well as upload new firmware and configuration files.

40.1 Filename Conventions

The configuration file (often called the romfile or rom-0) contains the factory default settings in the menus such as password, DHCP Setup, TCP/IP Setup, etc. It arrives from ZyXEL with a “rom” filename extension. Once you have customized the Prestige'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. With many FTP and TFTP clients, the filenames are similar to those seen next.

Only use firmware for your Prestige’s specific model. Refer to the label on the bottom of your Prestige.

ftp> put firmware.bin ras

This is a sample FTP session showing the transfer of the computer file " firmware.bin" to the Prestige.

ftp> get rom-0 config.cfg

This is a sample FTP session saving the current configuration to the computer file “config.cfg”.

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 Prestige only recognizes “rom-0” and “ras”. Be sure you keep unaltered copies of both files for later use.
