Power control and monitoring systems are used in computer systems to prevent damage to the computer and loss of data. One method of accomplishing this is to duplicate control hardware. This approach is not always economically justified and can introduce additional failure mechanisms that would not exist in a single control hardware approach. A power/cooling control system is described in the following that offers an alternative method to protect a computer system, without any additional cost, complexity and duplication of failure modes. The premise here is that because each power unit can exist without assistance from the microprocessor controller, a double fault must occur before the power/cooling system is shut down. The power/cooling control system is comprised of two elements.
