In order to cool heat generating components mounted on circuit packs plugged into a backplane wiring board mounted in a compact cabinet, in which the backplane would normally prevent a stream of cooling gas entering the front of the cabinet from flowing evenly over the heat generating components, a flow control baffle is placed on each side of the backplane to direct cooling gas entering the cabinet to the rear of the circuit packs and then around the backplane to a plenum formed by the backplane and a rear surface of the cabinet where the gas is exhausted by a fan. The exhaust of the cooling gas by the fan causes the level of the cooling gas pressure in the plenum to decrease, thereby urging additional cooling gas to enter the cabinet through louvers formed in the front surface of the cabinet.
