For redundancy, an HCP G11 Node has two power supplies. These power supplies should be connected to two different PDUs, which should be plugged into two separate power sources. This setup ensures that the entire power system has no single point of failure.
If only one power source is available, the two PDUs should be plugged into different circuits. If only one circuit is available, the two power supplies can be connected to the same PDU as a last resort, assuming the PDU has two available outlets and enough power capacity.
The power system input can be either single-phase or three-phase with single phase on the outlets.
