System Maintenance 24.5 - 24.7
This chapter covers menus 24.5 through 24.7. Use these menus to backup and restore your 
configuration file, as well as upload new firmware and configuration files.
35.1  Filename Conventions
The configuration file (often called the romfile or rom-0) contains the factory default settings 
in the menus such as password and TCP/IP Setup, etc. It arrives from ZyXEL with a rom 
filename extension. Once you have customized the ZyXEL Device'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. 
ftp> put firmware.bin ras
This is a sample FTP session showing the transfer of the computer file " firmware.bin" to the 
ZyXEL Device.
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 ZyXEL Device only recognizes “rom-0” and 
“ras”. Be sure you keep unaltered copies of both files for later use.
