1. A power distribution apparatus comprising:
a housing configured to be mounted into or on a rack that has a plurality of shelf positions;
power inputs coupled to the housing, the power inputs configured to receive one or more of: a first alternating current (AC) power, a first direct current (DC) power, a first single-phase fault managed power, or a first multi-phase fault managed power;
at least one fault managed power module configured to be contained in the housing, the at least one fault managed power module including a power transmitter configured to generate an output of a second single-phase fault managed power or a second multi-phase fault managed power from an input of the one of more of: the first AC power, the first DC power, the first single-phase fault managed power or the first multi-phase fault managed power; and
a plurality of connectors on the housing and configured to provide cable connections to one or more of the plurality of shelf positions of the rack for one or more of: the second single-phase fault managed power or the second multi-phase fault managed power.
 
10. A power distribution apparatus comprising:
power inputs configured to receive one or more of: a first alternating current (AC) power, a first direct current (DC) power, a first single-phase fault managed power, or a first multi-phase fault managed power;
a bus bar configured to mount to a rack that has a plurality of shelf positions, the bus bar having a plurality of module positions, each of the plurality of module positions configured to removably receive a respective one of a plurality of power processing modules, each of the plurality of power processing modules is configured to generate an output of one of a plurality of power types of: a second single-phase fault managed power, a second multi-phase fault managed power, Power-over-Ethernet (PoE) power and data, a second DC power, or a second AC power from an input of the first AC power, the first DC power, the first single-phase fault managed power, or the first multi-phase fault managed power, each of the plurality of power processing modules of a first type is interchangeable in any of the plurality of module positions with a corresponding one of the plurality of power processing modules of a second type, wherein at least one of the input or the output of the first type of the plurality of power processing modules is different from at least one of the input or the output of the second type of the plurality of power processing modules; and
a plurality of connectors configured to provide cable connections to one or more of the plurality of shelf positions of the rack for the one or more of the plurality of power types of: the second AC power, the second DC power, the PoE power and data, the second single-phase fault managed power, or the second multi-phase fault managed power.
