7.3 Executing Firmware Update

After configuring the firmware update settings in the configuration file, the firmware will be updated when the
configuration file is downloaded. The firmware update procedure is detailed below.
The firmware update process
Step 1
The unit downloads a configuration file from the
provisioning server.
•
For details about setting the timing of when
configuration files are downloaded, see
2.4.3.4 Downloading Configuration Files.
Step 2
The unit compares the version number of the
firmware in the configuration file to the unit's current
firmware version.
(In this example, the unit is using version 01.000 and
the configuration file specifies version 01.050.)
Step 3
When a newer firmware version is specified in the
configuration file, the unit is restarted. Then, the unit
will download the firmware from the address
specified under "FIRM_FILE_PATH" in the
configuration file.
Step 4
Once the newer firmware is downloaded, it is applied
to the unit and the unit automatically restarts.
