Upgrading the SG Appliance

When an upgrade to the SGOS software becomes available, you can download it through the Internet and install it. You can also download it to your PC and install it from there.

Important: Enable the auto-detect encoding feature on your browser so that it uses the encoding specified in the console URLs. The browser does not use the auto- detect encoding feature by default. If auto-detect encoding is not enabled, the browser ignores the charset header and uses the native OS language encoding for its display.
