In an HCP system, all electrical components are designed to be redundant. For each device in the system, there are either two power supplies or two of the devices so that there is no single point of failure if a power supply or PDU fails. In addition, since all components are redundant, the PDUs on different sides of the rack connect to different power systems, providing power system redundancy.
When an HCP system component with two power supplies is operating normally, each power supply contributes half the power that the device requires. If one power supplies fails, the HCP component continues to run on the single available power supply.
The table below describes the amperages and voltages of the different PDU models.
PDU model | Amperage | Voltage |
