The firmware update process
Note
•
Downgrading the firmware is not recommended. Operation cannot be guaranteed after performing
a downgrade.
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
2.2.4 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 will download the
firmware from the address specified under
"FIRM_FILE_PATH" in the configuration file.
