A gas distribution unit for use in a rack, that holds rack-mounted equipment that produces heat during operation, includes a housing defining a cavity, an exhaust port in a top wall of the housing, and at least one intake port configured to provide fluid communication between the cavity and a volume of gas external to the housing, the at least one intake port being at least partially laterally displaced relative to the exhaust port, the housing being configured to be disposed in and coupled to the rack and to direct gas from the cavity substantially directly upward through the exhaust port when coupled to the rack, and at least one fan coupled to and disposed within the housing and configured to draw gas through the at least one intake port, and to force the drawn-in gas out of the gas distribution unit through the exhaust port.

1. A method of cooling equipment modules disposed in a rack of equipment modules, the modules being disposed above one another in the rack, the modules including fans to draw gas from fronts of the modules through the modules and to expel the gas from backs of the modules, the modules having corresponding fronts, the method comprising:drawing gas from a bottom region near a bottom of the rack; guiding the gas to a lower front region disposed below the fronts of the modules; and pushing the gas upward from the lower front region into an upper front region adjacent the fronts of the modules while inhibiting the gas from initially flowing into portions of the rack other than the upper front region. 2. The method of claim 1 wherein the inhibiting comprises containing the gas upstream from the upper front region.3. The method of claim 1 wherein the guiding comprises using a flexible plenum coupled to a surface defining an opening that provides access to cool gas, the drawing and pushing comprising drawing and pushing the cool gas.4. The method of claim 1 further comprising filtering the gas drawn from the bottom region.5. A method of cooling equipment modules disposed in a rack of equipment modules, the modules being disposed above one another in the rack, the modules including fans to draw gas from fronts of the modules through the modules and to expel the gas from backs of the modules, the modules having corresponding fronts, the method comprising:inducing gas from a bottom region near a bottom of the rack to flow into a housing disposed in the rack; guiding the gas from the bottom region vertically through an intake port of the housing and horizontally through the housing to a lower front region disposed below the fronts of the modules; and urging the gas upward from the lower front region through an output port of the housing into an upper front region adjacent the fronts of the modules while inhibiting the gas from initially flowing into portions of the rack other than the upper front region. 6. The method of claim 5 wherein the inhibiting comprises bounding the gas with the housing and the urging comprises urging the gas from the lower front region into the upper front region through an exhaust port of the housing configured to direct the gas into the upper front region.7. The method of claim 5 wherein the vertically guiding comprises using a flexible plenum coupled to a surface defining an opening that provides access to cool gas, the inducing and urging comprising inducing and urging the cool gas.8. The method of claim 5 further comprising filtering the gas induced to flow from the bottom region.
