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.
34.1 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

Only use firmware for your Prestige’s specific model. Refer to the label on the bottom of your
Prestige.
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.
The following table is a summary. Please note that the internal filename refers to the filename on the
Prestige and the external filename refers to the filename not on the Prestige, that is, on your computer,
local network or FTP site and so the name (but not the extension) may vary. After uploading new
firmware, see the ZyNOS F/W Version field in Menu 24.2.1 – System Maintenance – Information
to confirm that you have uploaded the correct firmware version. The AT command is the command
you enter after you press “y” when prompted in the SMT menu to go into debug mode.
