Prestige 642 ADSL Internet Access Router
P642.ROM or similar. Once you have customized the Prestige's setting, they can be saved back to
PC/workstation under a filename of your choosing. Choose something meaningful, e.g. "MyP642.cfg".
The ZyNOS firmware file (sometimes referred to as the ras file) is the file that contains the ZyXEL
Network Operating System firmware and usually is the router model name with a *.bin extension, e.g.,
P642.bin.
With serial (xmodem) transfer, the filenames on the PC are your choice. With many ftp and tftp clients,
they are as well as seen next.
ftp> put P642.bin ras
This is a sample ftp session showing the transfer of the PC file "P642.bin" to the Prestige.
ftp> get rom-0 MyP642.cfg
This is a sample ftp session saving the current configuration to the PC file MyP642.cfg.
If your [t]ftp client does not allow you to have a destination filename different from the source, you will
need to rename them as the Prestige 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
Prestige and the external filename refers to the filename not on the Prestige, i.e., on your workstation, local
network or ftp site and so the name (but not the extension) will vary. The AT command is the command
you enter after you press "Y" when prompted in the SMT menu to go into debug mode.

10.4.1 Firmware Development

It is important to upgrade your firmware regularly, especially if there are problems. If you discover an
unexpected behavior, or bug, see if your problem is mentioned in the release notes. Load it according to
instructions (e.g., see if the default configuration file is needed also). If the problem still exists, e-mail or
call tech support.
