Administration Standard 2.1
Performing a firmware upgrade
This section describes how to perform a firmware upgrade on your Digital
Telephone IP Adapter unit. You perform the upgrade over the IP network using
the TFTP protocol. You can perform the Digital Telephone IP Adapter upgrade
manually or configure the Digital Telephone IP Adapter unit to perform an
automatic or scheduled firmware upgrade. Refer to “Auto upgrade
configuration” on page 133 for further details.
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.
Manual firmware upgrade
To ensure trouble-free communication between the RLC and Digital Telephone
IP Adapter units during and after the manual firmware upgrade, Nortel
recommends that you perform the upgrades as follows:
1 Create backup configuration files for the Digital Telephone IP Adapter unit
and RLC. Refer to “Creating a backup configuration file” on page 159.
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 Digital Telephone IP Adapter unit firmware.
6 Restart the RLC.
7 Restart all upgraded Remote Gateway 9100 Series units.
8 Re-enable the PBX slot(s) where an RLC is installed.
