    Power dependency configuration

    In the Power Dependency Editor, you can draw a diagram of the entire physical infrastructure supporting the racks, including the power connections.When you open the Power Dependency Editor, some equipment may already be shown in the upper left corner. There may be more components hidden behind the one that is visible. If the diagram is empty, you must configure the physical infrastructure with rooms and equipment first.

    This editor includes equipment at PDU level and upstream to the switchgear, and equipment from the PDU and downstream that supports the racks, such as cooling units and pumps. The IT load of the racks is included in the PUE/DCiE calculation as an IT Load subsystem. Infiltration, lighting, and ventilation are also included as subsystems.

    You can move the components one at a time from the initial position in the corner. Then you can draw power connections between the components in the diagram to configure the power dependency setup of the entire physical infrastructure.

     Configuring power dependencies
    Configure the power dependencies between the equipment in the diagram to ensure the configuration accurately reflects the live physical infrastructure of your energy systems.

    1. In the Application bar, select Planning> EE Configuration to open the Power Dependency Editor.

    2. Drag the equipment shown in the upper left corner into any position in the diagram to reveal other pieces of equipment behind it, and continue to drag equipment from the upper left corner until all components are visible in the diagram.

      Tip

      Tip: Whenever you add new equipment to the infrastructure in > Planning> Data Center, it appears in the upper left corner of the Power Dependency Editor. To ensure you always see any new components in the diagram, move all components away from the upper left corner.


      If you have many components you do not want to see in the diagram, for example many cooling units you want to see as one subsystem, you can drag them on top of each other so you only see them as one.

    3. Move all the components into the appropriate position by dragging them, and resize them by pulling the corners as needed.
      The diagram does not show the exact position of the components, rather a line diagram representing the power connections between the components.
    4. Select the connection icon 102237593.png in the toolbar.
    5. Click on a component you want to connect from, and click the other component you want to connect to. If you are creating a PDU downstream connection, define the breaker involved in the power connection, by name, rating, and derating values.
      A line now connects the two components in the diagram, with an arrow indicating the downstream power connection.
    6. Repeat the above step to continue to draw connections, until all connections in the live physical infrastructure are represented in the diagram (except for racks and rack-mounted equipment).
      The rack-level power connections, for example from a PDU to a rack PDU is set up in the component properties in > Planning> Data Center.
    7. At any time, right-click a component to see the properties.
      The components now have a power path setup, and the load is included in the power capacity calculations. They also appear in the Equipment Browser, Power Dependency pane, Inventory Report, and Audit Trail Report.
