Claim 7:
8. 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 the power from the external power source in the 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;
wherein the physical negotiated link comprises a communication link with determined communication protocols for speed of communication and uni- or bi-directional communication capabilities between the driver and the network switch; and
wherein the driver is configured to monitor the physical negotiated link, and to instruct the driver to light the luminaire immediately upon loss of the physical negotiated link.
