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 335.
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.
The conversion does not affect configuration settings.
Nortel recommends that each time you perform a firmware upgrade, you first
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:
1 Obtain the firmware upgrade from Nortel.
For instructions, refer to “Obtaining the latest upgrade file” on page 337.
2 Extract the upgrade files from the file you received from Nortel.
3 Start the TFTP server application.
4 Ensure 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 9150 units requires that they be running the
same version in order for them to communicate with each other.
