Abstract: A cooling system includes a pumping unit including a pump cassette and a connection assembly for establishing electrical connections between the pumping unit and the pump cassette. The connection assembly includes a printed circuit board that is connectable to the pumping unit, a first blind mate connector that is connected to the printed circuit board, and second blind mate connector that is connectable to the first blind mate connector and is connectable to the pump cassette.

Abstract: The disclosure provides a system and method for control of a pump in a coolant distribution unit (CDU) for cooling electronic components. In some aspects, the CDU includes a reservoir pump unit (RPU). Aspects of the method include setting a control priority to a first value indicative of a client mode in which a first local controller generates a first speed signal for a first pump in response to an instruction received from a master controller. The method includes determining a first interval since a last communication from the master controller. If the first interval exceeds a present dead time, the method includes setting the control priority of the first local controller to a second value indicative of an autonomous mode in which the first local controller generates the first speed signal for the first pump based on one or more parameters stored in a memory of the first local controller.
