ABSTRACT:
Each printed circuit board (PCB) on a backpanel has an associated set of power supply studs and power supply pins at an edge of the backpanel. The PCBs can be powered commonly via power supply buses interconnecting the studs. Alternatively, the PCBs can be powered individually via respective power supply PCBs which are inserted into connectors formed partly by the power supply pins and partly by pins on an additional, power supply, backpanel which is mounted to extend contiguously from and in the same plane as the first backpanel. The two arrangements can be combined to power groups of PCBs individually with all of the PCBs in each group being powered commonly.
