Both the PPS/AC (PPS 0) and auxiliary PPS (PPS 1) incorporate current sharing to
operate in redundant and parallel operations. The peripheral power supply/AC
input provides three precharge outputs (3.3V, 5V, and 12V) to enable hot-plug
installation of system boards or PCMs into an active centerplane.
