Server infrastructure having independent backplanes to distribute power and to route signals

Embodiments of the present technique are directed to a backplane infrastructure. The backplane infrastructure may include a passive power backplane configured to distribute power and comprising a first set of alignment holes, a signal backplane configured to route interface signals and comprising a second set of alignment holes and a set of common alignment pins, each alignment pin having an axis, wherein the set of common alignment pins are inserted into the first set of alignment holes and the second set of alignment holes to align the passive power backplane and the signal backplane about the axis.
