Firmware images are generally documented as build numbers. New models may be released from a branch of the regular firmware release. As such, the build number found in the System Settings > Dashboard > System Information widget and the output from the
get system status CLI command displays this four-digit build number as the build number.
To confirm that you are running the proper build, the output from the
get system status CLI command has a
Branch Point field that displays the regular build number.
Ensure that FortiManager 7.2.1 can run on your FortiManager model. See Supported Models.
