Perform a firmware upgrade if you have determined that you are using out-of-
date firmware. For instructions on determining if you need to perform an 
upgrade, refer to “Verifying the firmware and software version” on page 191.

Each time you perform a firmware upgrade, the configuration database is also 
converted (if necessary) to a format that is compatible with the new firmware. 
Configuration settings are not affected by the conversion. 

Nortel recommends that, each time you perform a firmware upgrade, you create 
a backup copy of the converted configuration file, and store it in a safe secure 
location. 

It is important to complete the following steps before performing a firmware 
upgrade:

Obtain the firmware upgrade from Nortel.

For instructions, refer to “Obtaining the latest upgrade file” on page 193.

Extract the upgrade files from the file you received from Nortel. 

Start the TFTP server application.

Ensure the TFTP base directory reflects the directory where the firmware 
upgrade file you want to use resides.

The protocol for communication between the RLC and 
the Remote Gateway 9100 Series units requires that 
they be running the same version in order for them to 
communicate with each other.
