iDRAC7 features are available based on the purchased license (Basic Management, iDRAC7 Express, or iDRAC7 Enterprise). Only licensed features are available in the interfaces that allow you to configure or use iDRAC7. For example, iDRAC7 Web interface, RACADM, WS-MAN, OpenManage Server Administrator, and so on. Some features, such as dedicated NIC or vFlash requires iDRAC ports card. This is optional on 200-500 series servers.
iDRAC7 license management and firmware update functionality is available through iDRAC7 Web interface and RACADM.
