Upgrade

This section describes how to upgrade the system software through the web system.

Context

To upgrade the system software of a device, you need to upload upgrade files to the device, specify files for next startup, and restart the device to make the upgrade files take effect. The web system allows you to upgrade the system software on the GUI, simplifying the upgrade operations and improving efficiency.

NOTICE:

Ensure that the configurations are saved before you upgrade the system software.
Do not power off the device during the upgrade.
