23.1 Overview

This chapter explains how to upload new firmware, manage configuration files and restart your P-
79X.
Use the instructions in this chapter to change the device's configuration file or upgrade its firmware.
After you configure your device, you can backup the configuration file to a computer. That way if
you later misconfigure the device, 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 device to the original default settings. The firmware determines the device's available
features and functionality. You can download new firmware releases from your nearest ZyXEL FTP
site (or www.zyxel.com) to use to upgrade your device's performance.
Only use firmware for your device's specific model. Refer to the label on
the bottom of your P-79X.

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-79X'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.
