A wager gaming machine having software and components allowing for automatic powering on and off (also referred to as remote out-of-band power control) bypassing the need for human operator intervention is described. The gaming machine has a master gaming controller and a network interface. The interface includes an input port supporting a TCP/IP connection which can be used by another network component having the gaming machine's IP address. The gaming machine may also include a Web server operating on the input port. The Web server may receive HTTP messages on the input port even when the gaming machine is powered off. Thus, the machine is capable of receiving an HTTP message at the input port instructing the machine to power on. The gaming machine may also contain a manageability engine processor for executing an active management system software component. This component implements the Web server on the gaming machine.
