Administration
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, see "Verifying the firmware and software version" on page 310.

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 Networks 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
1 Obtain the firmware upgrade from Nortel Networks.
For instructions, see "Obtaining the latest upgrade file" on page 312.
2 Extract the upgrade files from the file you received from Nortel Networks.
For instructions, see "Extracting upgrade files from the download file" on
page 313.
3 Start the TFTP server application.
4 Ensure the TFTP base directory reflects the directory where the firmware
upgrade file you want to use is located.
