Abstract
A networked driver for a powered device (PD) includes an input connection capable of receiving power and data from an external power and data source, one or more output connections capable of supplying power and data to the PD, and a circuit capable of initiating delivery of a predetermined amount of power to the external load when a physical negotiated link between the external power and data source is lost.
Claims19
A network driver for a powered device (PD), comprising:
- an input connection capable of receiving power and data from an external power and data source;
- one or more output connections capable of supplying power and data to the PD;
- and
- a circuit capable of initiating delivery of a predetermined amount of power to the external load when a physical negotiated link between the external power and data source is lost.
1 more element
A power over Ethernet (PoE) lighting system, comprising:
- power sourcing equipment (PSE) comprising a midspan configured to receive power from an external power source in normal operation, and a network switch configured to receive power from the external power source in normal operation;
- a PoE powered luminaire;
- and
- a driver coupled between the midspan and the luminaire to receive power and data from the midspan and deliver power and data to the luminaire;
- wherein the network switch is configured to provide a physical negotiated link between the network switch and the driver via the midspan.
2 more elements
A method of operating power over Ethernet (PoE) device, comprising:
- monitoring a physical negotiated link between a network driver and a power source;
- in the event the physical negotiated link is lost, initiating power delivery to the PoE device to turn the PoE device on to an emergency operation mode.
