Abstract

In example implementations, an apparatus is provided. The apparatus includes a plurality of power inputs, a plurality of power outputs, a power management component, and a power source capability information translation component. The plurality of power inputs is coupled to power sources. The plurality of power outputs is coupled to electronic devices. The power management component is coupled to the plurality of power inputs and the plurality of power outputs to manage deliver of power. The power source capability information translation component is coupled to the power management component and an external source that provides a power source capability information of a power source connected to a power input of the plurality of power inputs. The power management component delivers the power from the power source to a power output of the plurality of power outputs in accordance with the power source capability information received from the external source.

First claim

The invention claimed is:

1. An apparatus, comprising:
a plurality of power inputs coupled to power sources;
a plurality of power outputs coupled to electronic devices;
a power management component coupled to the plurality of power inputs and the plurality of power outputs to manage delivery of power;
a power source capability information translation component coupled to the power management component and an external source that provides a power source capability information of a power source connected to a power input of the plurality of power inputs, wherein the power management component delivers the power from the power source to a power output of the plurality of power outputs in accordance with the power source capability information received from the external source.

2. The apparatus of claim 1 , wherein the plurality of power inputs and the plurality of power outputs comprise a direct current (DC) power interface.

3. The apparatus of claim 1 , wherein the power management component is to monitor a power delivered from each of the plurality of power inputs and power delivered to each of the plurality of power outputs.

4. The apparatus of claim 3 , wherein the power management component is to regulate the amount of power delivered from the plurality of power inputs based on the power that is monitored.

5. The apparatus of claim 3 , wherein the power management component is communicatively coupled to the external source to report a status of the power that is monitored from the plurality of power inputs.

6. The apparatus of claim 1 , wherein the external source comprises an input switch.

7. The apparatus of claim 1 , wherein the external source comprises a remotely located power environment console.

8. The apparatus of claim 7 , further comprising:
a management interface communicatively coupled to the power management component and the remotely located power environment console.

9. The apparatus of claim 8 , wherein the management interface is communicatively coupled to a status indicator to communicate an alert or a status.

10. A method, comprising:
receiving, via a power source capability information translation component of an adapter that is coupled to an external source, a power source capability information from the external source, wherein the power source capability information is associated with a power source connected to a power input of a plurality of power inputs of the adapter; and
delivering, via a power management component of the adapter that is coupled to the plurality of power inputs, a plurality of power outputs, and the power source capability information translation component of the adapter, power from the power source to an electronic device connected to a power output of the plurality of power outputs of the adapter in accordance with the power source capability information received from the external source.

11. The method of claim 10 , wherein the external source comprises a physical input switch or a remotely located power environment console.

12. The method of claim 11 , wherein a power source capability information from the remotely located power environment console overrides a power source capability information from the physical input switch.
