Physical appliances are shipped with the operating system already installed. If you need to install the operating system, use the following procedure to reimage the drive from an ISO file.
ISO files are maintained on the Symantec FileConnect site. You need your maintenance serial number to access FileConnect and download the ISO file. You can find your serial number on the license certificate you received with you initial purchase or on a Version Upgrade Notification. If you need help locating your serial number, contact Symantec Customer Care.
