Upgrading the Gateway
Firmware and Downloading
Configuration Files
The Gateway, when shipped, has code already installed in its Flash ROM memory and is ready
to run. This section describes the process for upgrading the Gateway’s firmware with a new
version of the ROM image. New ROM images can be obtained from the vendor of your
Gateway. This section also describes how to download configuration files to the Gateway.
A convenient way to set up the Gateway configuration is to download the configuration file to the
Gateway.
You can set downloading of the configuration file to the gateway to occur in any of the following
three ways:
•
Manual download
The configuration file and upgrade versions are downloaded directly via Telnet (see
Downloading the File Manually using Telnet
or the Web (see
Versions over the Web via the TFTP Server
and
Downloading Code Versions over
•
DHCP server auto configuration
(see
on page
The configuration file and upgrade versions are downloaded automatically using a DHCP
server that is based at the provider’s network. The TFTP/HTTP server IP address and the file
name are provided by the DHCP server during the Bootp process and at half lease time. You
can set DHCP server Automatic Configuration either via the Web (see
Automatic Configuration via the Web
on page
) or via Telnet (see
on page
•
Fixed (provisioned) TFTP/HTTP Auto Configuration
The configuration file and upgrade versions are downloaded automatically as needed during
boot and at fixed polling intervals using a TFTP/HTTP server based at the provider’s network.
The TFTP/HTTP server IP address and the file name are provisioned into the gateway. You can
set Fixed Automatic Configuration either via the Web (see
“Root” Configuration File via the Web
on page
) or via Telnet (see
“Root” Configuration File via Telnet
on page
).
Two kinds of configuration files can be downloaded:
1.
“Root” configuration file - the first file to be downloaded. This file can include any of the
Gateway configuration parameters and three execution flags. Each execution flag, when set, can
initiate one of the following possible actions:
•
Downloading a secondary General configuration file
•
Upgrading the Gateway Application firmware
•
Upgrading the Gateway Loader firmware
