This chapter explains how to upload new firmware, manage configuration files and restart 
your ZyXEL Device. 

Note: Do not interrupt the file transfer process as this may PERMANENTLY 

DAMAGE YOUR ZyXEL Device. 

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.

Note: Only use firmware for your device’s specific model. Refer to the label on the 

bottom of your ZyXEL Device.

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 ZyXEL Device'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 
ZyXEL Device.

ftp> get rom-0 config.cfg
