VES-1000 Series Ethernet Switch
Firmware and Configuration File Maintenance 10-1
This chapter tells you how to back up and restore your configuration file as well as upload new firmware
and a new configuration file.
10.1 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 VES-1000 Series 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. 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 VES-1000 Series
switch.
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 VES-1000 Series switch 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 VES-1000
Series switch and the external filename refers to the filename not
on the VES-1000 Series switch, 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.
