The DC power distribution unit (DC PDU) supplies DC power to payloads connected to DC power outlets. You can read the current sensor and voltage sensor on the DC power outlet to monitor the DC power supply. Each outlet can be turned off and on individually.

In certain circumstances, a rack with DC PDU installed may return an empty DCPowerDistributionUnits array from IAteCoreSession. A DC PDU is only detected when the RackPowerState has been set to the Running state at least once. To set the rack power state to Running state, press the power button on the rack or call SetRackPowerStateToRunningAsync. Then, trigger the system to update the DC PDU list by calling RefreshDCPowerDistributionUnitsAsync.

Note DC PDU control and sensor readings are only accessible when the ATECCGEN2 rack is in the Running power state. When the rack is not in the Running power state, attempting to read a sensor returns Double.NaN and attempting to enable or disable an outlet triggers an exception.

Checking Rack Power State, Setting Power State to Running, Calling RefreshDCPowerDistributionUnitsAsync, and Reading Current and Voltage Sensors for all DC Power Outlets
