Abstract
A system for dissipating heat from a power supply enclosed within a housing having an air inlet and outlet. The system includes fans disposed in a plenum structure adapted to fit over the housing to thereby establish air communication between the fans and the housing inlet so that operation of the fans causes air to flow through the inlet, the power supply, and out through the outlet, thereby dissipating heat from the power supply. Each fan is operable independent of any other of the fans. The relationship between the fans may be serial, parallel, or a combination of serial and parallel. The fans are monitored to detect failure of any of the fans and, upon such detection, an alert is activated.
