To upgrade through USB, you need to store the required upgrade file in a USB flash drive, insert it into the FW, and upload the upgrade file in the USB flash drive to upgrade the FW.
In manual upgrade, you need to run the upgrade command after inserting a USB flash drive to upgrade system software and configuration files.
In automatic upgrade, the FW automatically upgrades after the USB flash drive is inserted. This method simplifies operations and enhances the upgrade efficiency.
If no configuration file exists, the FW starts the upgrade after the USB flash drive is inserted.
In this scenario, you need only to store all required upgrade files in the USB flash drive and insert it into the FW, requiring no command execution.
