Performing a firmware upgrade

This section describes how to perform a firmware upgrade on your Remote
Gateway 911x series unit. You perform the upgrade over the IP network using
the TFTP protocol. You can perform the Remote Gateway 911x series unit
upgrade manually or configure the Remote Gateway 911x series unit to perform
an automatic or scheduled firmware upgrade. Refer to "Auto upgrade
configuration" on page 128 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 Remote Gateway
911x 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 911x series unit
and RLC. Refer to "Creating a backup configuration file" on page 157.
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 911x series 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.
