Performing a firmware upgrade
This section describes how to perform a firmware upgrade on your RLC. You
perform the upgrade over the IP network using the TFTP protocol. You can
perform the RLC upgrade manually or configure the RLC to perform an
automatic or scheduled firmware upgrade. Refer to "Auto upgrade
configuration" on page 228 for further details.
You must have a TFTP server application running on the administration PC.
Ensure that the TFTP server's base directory points to the directory that contains
the upgrade files.
Manual firmware upgrade
To ensure trouble-free communication between the RLC and Remote Gateway
9100 Series units during and after the manual firmware upgrade, Nortel
recommends that you perform the upgrades as follows:
1
Create backup configuration files for the Remote Gateway 9150, Remote
Gateway 911x series, and Digital Telephone IP Adapter units and for the
RLC. Refer to "Creating a backup configuration file" in the Nortel Installation
and Administration Guide for the specific product.
2
Upgrade the Configuration Manager software on the administration PC.
3
Disable the PBX slot(s) where an RLC is installed.
4
Upgrade the RLC firmware.
5
Upgrade the Remote Gateway 9150, Remote Gateway 911x series, and
Digital Telephone IP Adapter unit firmware.
6
Remote Gateway 9150 units only - Upgrade the BRI module firmware for
each BRI module.
7
Restart the RLC.
8
Restart all upgraded Remote Gateway 9100 Series units.
9
Re-enable the PBX slot(s) where an RLC is installed.
Note: Upgrade the Remote Gateway 9150 unit's firmware before upgrading
