Abstract:
A data server, comprising:a cabinet having a plurality of slots therein,a backplane section disposed at a rear of the slots, such backplane section having mounted thereto a corresponding plurality of first multi-pin electrical connectors;a plurality of hot replaceable, DC powered, processing unit modules, each one having a printed circuit board, each printed circuit board having a second multi-pin electrical connector adapted be plugged into, or un-plugged from a corresponding one of the first multi-pin electrical connectors of the backplane; andwherein such backplane comprises:a coaxial connector having a center conductor and an outer conductor;a first strip conductor disposed on one surface of a dielectric substrate of the backplane, such strip connector being electrically connected to the center conductor of the coaxial connector and to a first pin of the first multi-pin electrical connector;a second strip conductor disposed on an opposite surface of the dielectric substrate of the backplane, such second strip connector being electrically connected to the outer conductor of the coaxial connector and to second pin of the first multi-pin electrical connector, such first and second pins of the first multi-pin electrical connector being electrical connected to a pair of pins of the second multi-pin electrical connector when the module is plugged into the backplane;the first and second strip conductors being in an overlaying relationship to form a transmission line passing from the coaxial conductor to the electrical connector.
