Abstract: A fault tolerant system by which individual components of a server are monitored and controlled through independent, programmable microcontrollers interconnected through a microcontroller network. An external agent can control and monitor the microcontrollers by extending the interconnection network beyond the physical server. The extension to the interconnection network converts protocols between media, and directs the microcontrollers and the state managed by the microcontrollers. Intervention of the server operating system software is not required and is not utilized for the access and control operations. A remote interface board provides the interface between the microcontroller network and an external modem that communicates with a remote client computer. The remote interface board also provides for connection to a local client computer.

Abstract: A fault tolerant system for independent powering of diagnostic processes through a remote interface by use of a serial (local) or modem (dial-in) gateway. A server connects to a local or remote facility which includes a client computer. If the internal server power is off, the remote interface provides independent external power to portions of the server to facilitate reading of the server internal status or to remotely power up the server from the client computer. The remote interface provides bias power to a chassis microcontroller and a system recorder comprising a non-volatile memory and a microcontroller. The management of the server devices is directed by a network of microcontrollers without intervention of the server operating system software.
