Chapter 12 Firmware and Configuration File Maintenance

This chapter tells you how to back up and restore your configuration file as well as upload new firmware and a new configuration file.

12.1Filename 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 ExpWave'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 ExpWave.

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 ExpWave 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 ExpWave and the external filename refers to the filename not on the ExpWave, 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.

DESCRIPTION

Configuration

Rom-0

This is the configuration filename on the

File

 

ExpWave. Uploading the rom-0 file replaces the

 

 

 

entire ROM file system, including your ExpWave

 

 

 

configurations, system-related data (including the

 

 

 

default password), the error log and the trace log.

 

 

 

 

 

Firmware

Ras

This is the generic name for the ZyNOS firmware

on the ExpWave.

 

12.2Backup Configuration

The ExpWave displays different messages explaining different ways to backup, restore and upload files in

menus 24.5, 24.6, 24. 7.1 and 24.7.2; depending on whether you use the console port or Telnet.

Option 5 from Menu 24 - System Maintenance allows you to backup the current ExpWave configuration to your computer. Backup is highly recommended once your ExpWave is functioning properly. FTP is the preferred method for backing up your current configuration to your computer since it is faster. You can also perform backup and restore using menu 24 through the console port. Any serial communications program should work fine; however, you must use Xmodem protocol to perform the download/upload and you don’t have to rename the files.
