Introduction
30.1
Use the instructions in this chapter to change the Contivity 221's configuration file or upgrade its
firmware. After you configure your Contivity 221, you can backup the configuration file to a
computer. That way if you later misconfigure the Contivity 221, 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 Contivity 221 to the original default settings.
The firmware determines the Contivity 221'savailable features and functionality. You can
download new firmware releases from
your Contivity 221's performance.
Filename Conventions
30.2
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 Nortel Networks
with a "rom" filename extension. Once you have customized the Contivity 221'ssettings, they can
be saved back to your computer under a filename of your choosing.
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.
