When the switch is physically isolated from the Internet and no proxy server is deployed on the enterprise intranet, you can update the SA-SDB locally. Before performing local upgrade, obtain the SA-SDB upgrade file and upload or download the upgrade file to the switch using SFTP, FTP, or TFTP.
You are advised to store the upgrade file in the root directory of the storage device.
The upgrade file is in .zip and can be directly uploaded to the switch without the need of decompressing it.
For details about how to upload or download the upgrade file, see File Management.

The local SA-SDB is manually upgraded.
