An enclosure arrangement includes a chassis, and a central electronics complex. The central electronics complex has a cage removably positioned within the chassis. The cage has an open top providing access into the interior of the cage. The central electronics complex also includes a backplane arranged in a horizontal position, and forming a floor of the cage. The backplane has at least one card slot on a surface thereof. The central electronics complex further includes at least one circuit board disposed in the interior of the cage and being removably received by the card slot. The circuit board is arranged in a vertical position so that a gravitational force helps retain the circuit board in the card slot. The cage is removably positioned within the chassis. At least one rail connects the cage to the chassis. The cage is disposed on the rail, and is guidable into the chassis using the rail.

Enhanced enclosure arrangement for a computer

A cooling system for a host device affords enhanced reliability using multiple blower units mounted in parallel between a low pressure plenum and a high pressure plenum and a control system that senses when a blower unit is failing or has failed and responds by shutting down the failed unit and increasing the speed of the remaining blowers to maintain the air flow volume delivered to the cooling path. To maintain the integrity of the cooling air path while affording continuous operation of the host device, a spring biased closure door seals the access opening through which the blower is mounted when a blower unit is removed and displaced by the blower unit to an inoperative position against the biasing force of the spring when the blower unit is installed or replaced. To prevent recirculation through a vacated blower unit mounting space, a one way air flow device, in the form of a shutter assembly including plural pivoting louvers or vanes is mounted at the exhaust location of each blower. Thus the cooling air delivery is maintained and a blower unit can be removed for maintenance or replacement without interruption or impairment of host device operation.
