Abstract
A plurality of electronic apparatuses, each apparatus having a closed loop cooling system, are installed in a cabinet having another closed loop fluid cooling system. Each of the closed loop fluid cooling systems includes a heat receiver and a pump. A projection is mounted on the electronic apparatus and a switching valve is arranged on the cabinet to stop or start circulation of a cooling fluid.
