Performing a firmware upgrade

Introduction
This section describes how to perform a firmware upgrade on your Remote
Office 9150 unit. You perform the upgrade over the IP network using the TFTP
protocol.
You must have a TFTP server application running on the administration PC. The
TFTP server's base directory must point to the directory that contains the
upgrade files.
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 338.

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.

CAUTION
Risk of incorrect operation
You must ensure that the MIG RLC's firmware has been upgraded
before you upgrade the Remote Office 9150 unit's firmware. This
ensures that communication problems between the MIG RLC and
Remote Office 9150 unit do not occur.
