Performing a firmware upgrade

This section describes how to perform a firmware upgrade on your Meridian
Digital Telephone IP Adapter 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, refer to "Verifying the firmware and software version" on page 139.

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

It is important to complete the procedures described under "Obtaining the latest
upgrade file" on page 141 before performing a firmware upgrade. Then you
must complete the following steps:
1 Start the TFTP server application.
2 Ensure the TFTP base directory reflects the directory where the firmware
upgrade file you want to use resides.
