diagrams the AC power supply system of the CX600-X16. The input AC power is
converted into regulated DC power by an EPS200-4850A. The resulting DC power output is
connected to the PEMs through external cables to supply power for all boards and fan modules.
Two -48V power inputs are joined on the board.
, each DC power input contains one -48 V power input and one RTN input. Two
separated RTN inputs are joined on the board.
