Chapter 38
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.
38.1 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.
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.
