Abstract: A fail-safe static switch for controlling the supply of redundant electrical power to critical loads. A first control path has a signal analyzer configured to monitor predetermined characteristics of a power supply voltage. The signal analyzer generates a first failure signal when the characteristics of the power supply voltage monitored by the signal analyzer are not in compliance with predetermined metrics. A second control path has a first electrical circuit configured to monitor predetermined characteristics of the power supply voltage. The first electrical circuit generates a second failure signal when the characteristics of the power supply voltage monitored by the first electrical circuit are not in compliance with predetermined metrics. The fail-safe static switch further includes an output providing an electrical output signal. The electrical output signal changes state when at least one of the first failure signal and the second failure signal are generated.

Abstract: A cooling system having a source of pressurized intake air includes a primary fan and a secondary fan spaced apart from the primary fan. The pressurized intake air flows from either of the primary or secondary fans. Ductwork includes an inlet, at least one generally hollow supply plenum in fluid communication with the inlet, and at least one supply opening in fluid communication with the supply plenum. The pressurized intake air is urged into the inlet, through the supply plenum and out of the supply opening as a first air supply. The supply opening is configured to direct the first air supply toward at least one first heat generator. The secondary fan is configured to operate in a predetermined manner corresponding to a status of the primary fan.
