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

35.1 Introduction

Use the instructions in this chapter to change the P-792H v2's configuration file or
upgrade its firmware. After you configure your P-792H v2, you can backup the
configuration file to a computer. That way if you later misconfigure the P-792H v2,
you can upload the backed up configuration file to return to your previous
settings. You can alternately upload the factory default configuration file if you
want to return the P-792H v2 to the original default settings. The firmware
determines the P-792H v2's available features and functionality. You can download
new firmware releases from your nearest ZyXEL FTP site to use to upgrade your P-
792H v2's performance.

35.2 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. 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.
