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 AMG1001-T/AMG1011-T.

22.1.1 What You Need To Know About Firmware

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 AMG1001-T/AMG1011-T'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
AMG1001-T/AMG1011-T.
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 AMG1001-T/AMG1011-T 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 AMG1001-T/AMG1011-T and the external filename refers to the filename not on the AMG1001-
