Abstract
Abstract A circuit board module for a supercomputer includes quick connections for power, ground, coolant quick connects, and circuit quick connects. The quick connections provide for insertion of modules with substantial savings in time and effort. The electrical power and ground connections and the liquid coolant connections engage and disengage automatically upon insertion and removal of the modules. The circuit quick connects require only insertion of a camming tool for connection and disconnection. The modules require no bolting or unbolting of clamps or hoses for the various connections.
