10.4 Filename Conventions
The configuration file (sometimes called the romfile or rom-0) contains the settings in the menus such as
password, DHCP Setup defaults, TCP/IP Setup defaults, etc. The external (i.e., not on the Prestige)
configuration filename is usually the router model name with a *.rom extension. The ZyNOS firmware file
(sometimes called the “ras” file) contains the ZyXEL Network Operating System firmware and the external
firmware file is usually the router model name with a *.bin extension. Rename the configuration filename to
“rom-0” and the firmware filename to “ras” when transferring files to the Prestige (i.e., the internal
filenames on the Prestige). Renaming the files is not necessary when you transfer files using the Xmodem
protocol.
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, i.e., on your computer, local
network, or ftp site and so the name (but not the extension) will vary. Type the AT command after you
press
Y when prompted in the SMT menu to go into debug mode. After uploading the new firmware see the
ZyNOS F/W Version field in Menu 24.2.1 to check if you uploaded the correct firmware version.

Configuration
File Rom-0 *.rom This is the Prestige router configuration
filename. Uploading the rom-0 file
replaces the entire ROM file system,
including your Prestige configurations,
system-related data (also the speed and
default password), the error and trace
logs. ATLC

firmware on the Prestige. ATUR
10.5 Backup Configuration
Typing 5 in Menu 24 – System Maintenance allows you to backup the current Prestige configuration to
your computer. Backup is highly recommended once your Prestige is functioning properly.
You must perform backup and restore through the console port. Any serial communications program should
work fine; however, you must use Xmodem protocol to perform the download/upload.
Note that the terms “download” and “upload” are relative to the computer. Download means to transfer
from another computer to the workstation, while upload means from your computer to another computer.
