1. A system, comprising:
a first power supply configured to generate a first output voltage;
a second power supply configured to generate a second output voltage, wherein the second power supply is separate from the first power supply;
a first power conditioner coupled to the first power supply, wherein the first power conditioner comprises a first converter configured to supply the first output voltage to a first backplane; and
a second power conditioner coupled to the second power supply, wherein the second power conditioner comprises a second converter configured to supply the second output voltage to a second backplane, wherein the first backplane and the second backplane are electrically coupled to:
one or more load components configured to operate based on the first output voltage, the second output voltage, or both, wherein each load component of the one or more load components comprises an ORing circuit configured to switch between the first power conditioner and the second power conditioner via the first backplane and the second backplane, respectively; and
a control system comprising at least one processor that:
receives an instruction to start a diagnostic operation of the first converter;
transmits a first control signal to the first power conditioner to cause the first converter to increase a first electrical property in response to receiving the instruction;
receives a first indication of a second electrical property associated with the first backplane from a respective ORing circuit;
determines a difference between the second electrical property and a target electrical property;
determines that the difference is less than or equal to a threshold amount; and
in response to the difference being less than or equal to the threshold amount, generates an alert to indicate that the first converter outputs the second electrical property as equal to the target electrical property.
