If the command option reload is added, the system prompts whether to save the configuration, and whether to restart the device immediately. However, usually the device is started after all programs are upgraded. Therefore, the reload option is not recommended.

During the upgrade process, the device must not be powered off. Otherwise, the system may fail to start, or the file may be damaged.
