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 P-792H v2'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. Find this firmware at
www.zyxel.com.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 P-792H v2.
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 P-792H v2 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 P-792H v2 and the external filename refers to the filename
not on the P-792H v2, 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
Status screen to confirm that you have uploaded the correct firmware version.
