You can configure and manage system updates, proxy servers, and database updates on the Update page.

System Update

On the System Update page, you can upload an upgrade package to upgrade the device's software, as shown in the following figure.

Proxy

The device needs to access the Internet to upgrade embedded libraries. Suppose the device cannot access the Internet and an HTTP proxy server exists. In that case, you can set the proxy server on the Proxy Options page so that the device can access the Internet through the proxy server to upgrade embedded libraries. Select Enable Proxy Server, enter the proxy server's IP address and port number, select Authentication required, and enter the username and password. See the following figure.

Database Update

On the Database Update page, you can manage the upgrade of the virus database, URL database, system patch, application signature database, and audit rule database.

Click Enable to enable the automatic upgrade of embedded libraries, Disable to disable the automatic upgrade function and the Refresh icon to view real-time version information about embedded libraries.

Click Update Now to manually upgrade a rule library within the validity period of the upgrade service.

Click Rollback to roll back the rule library to the version before the upgrade. The application identification rule library and Ingress Rule Database support rollback.

Click Update Server. On the Update Server page, configure an upgrade server to which the device is to be connected. It is recommended that Auto Select Server be selected so that the device automatically detects an available upgrade server.
