Busbar connection with side band communications

Abstract

A busbar connector includes an insulator body, a positive power delivery contact, a negative power delivery contact, and a side band contact. The insulator body has first prong and a second prong oriented in a longitudinal direction and proximate one another with a gap therebetween. The positive power delivery contact is on a first inner surface of the first prong adjacent the gap, and the negative power delivery contact is on a second inner surface of the second prong adjacent the gap. The side band contact is positioned on the insulator body and insulated from the positive power delivery contact and the negative power delivery contact by the insulator body.

 detecting a presence of a server blade via a side band contact electrically coupled to a side band source of a busbar of the computing device rack system, 
 receiving instructions from a networked electronic device, and 
 transmitting a side band signal to the server blade through the side band source.

         12 . The busbar connector of  claim 7 , wherein the side band contact is insulated from the positive power delivery contact and the negative power delivery contact by at least 1 millimeter of the insulator body. 
     
     
         13 . The busbar connector of  claim 8 , further comprising a side band return protruding in a direction perpendicular to the longitudinal direction.
