Abstract: An apparatus and method for connecting servers within a rack-mounted server system. In one embodiment, a plurality of servers are positioned in respective bays of a rack. The bays generally constrain adjacent servers in a generally fixed spacing and in face-to-face alignment. A first server is moved within its bay relative to a second server until a connector on the first server is aligned with a mating connector on the second server. Alignment of the two mating connectors is detected by a position sensor, such as an LED-photodiode pair. A signal from the position sensor causes or at least allows the first and second connectors to be moved toward one another, either using a motor or a hand-actuated mechanism, to provide power and data communication between the servers. Once the connection is established, data is optionally transmitted via the optical sensor.

Abstract: Detecting, predicting, and diagnosing faults in a cooling system. According to one embodiment, a heat sink is in thermal contact with a heat-generating electronic component. When a temperature differential between the electronic component and the heat sink exceeds a set point, a fault signal is generated. The set point may be empirically or theoretically determined. The set point may be a static set point, or it may be a dynamic set point determined according to real-time operational parameters of the system. The system may be implemented with predictive failure analysis (PFA) to provide a more reliable, efficient, inexpensive, and robust computer system.

Abstract: A method of controlling the power-on of a computer system by providing a plurality of monitor lines interconnected with respective components of the computer system, monitoring the lines using a control circuit in response to a power-on reset signal, and executing a system power-on sequence in response to a determination by the control circuit that the components of the computer system are functioning properly. If the computer system has a plurality of CPU slots, the control circuit determines if a CPUs or terminator cartridges is plugged into the CPU slots, and determines that a properly matched CPU has been installed into the system, and that multiple CPUs contain compatible power supply requirements. Finally, the control circuit can determine that a power regulator is functioning properly.
