When to perform a firmware upgrade
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.
About firmware upgrades and configuration files
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.
Before you begin
It is important to complete the following steps before performing a firmware
upgrade:
1Obtain the firmware upgrade from Nortel.
For instructions, refer to “Obtaining the latest upgrade file” on page 193.
2Extract the upgrade files from the file you received from Nortel.
3Start the TFTP server application.
4Ensure the TFTP base directory reflects the directory where the firmware
upgrade file you want to use resides.

ATTENTION! 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.
