Firmware and Configuration File Maintenance 18-3
18.4.1 Filename Conventions
The configuration file (often called the romfile or rom-0) contains the factory default settings in the screens such
as password, switch setup, IP Setup, etc. It arrives from ZyXEL with a “rom” filename extension. Once you have
customized the switch'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.

DESCRIPTION
Configuration File Rom-0 *.rom This is the configuration filename on the switch. Uploading the
rom-0 file replaces the entire ROM file system, including your
switch configurations, system-related data (including the
default password), the error log and the trace log.
Firmware Ras *.bin This is the generic name for the ZyNOS firmware on the switch.
Example FTP Commands
ftp> put firmware.bin ras
This is a sample FTP session showing the transfer of the computer file " firmware.bin" to the switch .
ftp> get rom-0 config.cfg
This is a sample FTP session saving the current configuration to a file called “config.cfg” on your computer.
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 switch only recognizes “rom-0” and “ras”. Be sure you keep unaltered copies of both files for
later use.
Be sure to upload correct model firmware as uploading the wrong model firmware may damage
your device.
18.4.2 FTP Command Line Procedure
Step 1. Launch the FTP client on your computer.
Step 2. Enter “open”, followed by a space and the IP address of your switch.
Step 3. Press [ENTER] when prompted for a username.
Step 4. Enter your password as requested (the default is “1234”).
Step 5. Enter “bin” to set transfer mode to binary.
Step 6. Use “put” to transfer files from the computer to the switch, for example, “put firmware.bin ras” transfers
the firmware on your computer (firmware.bin) to the switch and renames it “ras”. Similarly, “put
config.rom rom-0” transfers the configuration file on your computer (config.rom) to the switch and
