Claim 0:
1. A power source supply control device for communication facilities, the power source supply control device being for supplying power source electric power to a plurality of independent loads constituting communication facilities respectively from a common main power source comprising:
a plurality of controllable switch units, implemented with one or more processors, configured to switch provision or non-provision of the power source electric power supply to the plurality of independent loads from one of the main power sources,
a plurality of load monitor units, implemented with one or more processors, each configured to monitor a state in each of one or more of the plurality of independent loads connected to downstream sides of the plurality of controllable switch units; and
a switch control unit, implemented with one or more processors, configured to control on/off of the plurality of controllable switch units sequentially, based on monitor situations of the plurality of load monitor units,
wherein the switch control unit:
specifies an energization switching order to the plurality of independent loads according to a predetermined state, wherein the plurality of independent loads includes a first load and a second load, and wherein the energization switching order indicates that the first load is switched on earlier than the second load that is an object to be switched,
receives an output of one of the load monitor units that monitors a state of the first load,
determines that the state of the first load becomes a state that meets a predetermined condition, and
switches on a switch unit that controls energization to the second load.
