22.1 Overview

This chapter explains how to upload new firmware and manage configuration files.
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-660RU-Tx.

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-660RU-Tx'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.
