A network device includes a web server chip that is connectable to a computer network. The web server chip includes an embedded processor that is programmable to function as a manageability web server, obtain manageability information about the network device and send the manageability to a network manager. The web server chip further includes an interface for communicating with an IC bus in the network device. The embedded processor is programmable to obtain manageability information about devices connected to the IC bus. The embedded processor is also programmable to control fan controllers, power supply controllers and other controllers connected to the IC bus. This, in turn, allows a network manager to command the web server chip to remotely power up and power down the network device. Thus, the web server chip can perform network management functions without burdening the host processor of the network device. If network communications are performed via HTTP, the embedded processor can be programmed to implement an HTTP server, and the network manger can use a web browser and HTML files to run network management software.

Web server chip for network manageability

A chip for a device such as a computer includes a media access controller and an embedded processor. The embedded processor is programmed to function as a web server and provide network manageability information to a network manager. The embedded processor is also programmed to function as a LAN controller. When a packet is received by the media access controller, the embedded processor examines a destination address of the packet and routes the packet to an appropriate end point. Packets having a first unique destination address are routed to a host interface (and eventually to a host processor), and packets having a second unique address are routed to the embedded processor-functioning-as-web server. Thus, the chip allows network management and local area network communications to be performed over a single physical interface.
