PDU Power Cord Facility Grid Relationship

Six PDU power cords provide power to the two PDUs in the rack. The server power cords within the rack connect to the PDUs.

When facing the rear of the server, the three PDU A (left) power cords connect to one facility AC power grid, and the three PDU B (right) power cords connect to another AC power grid. See Facility Power Requirements for more information.

Note -  To ensure the redundant operation of the power supplies, connect the server chassis power cords to alternate the PDUs. When connected to alternate PDUs, the power supplies provide 1+1 (2N) redundancy in case of a power failure to a single AC power grid.
