Abstract
The invention relates to a PoE lighting system () comprising an emergency lighting device (), a first PSE device () and a second PSE device (). The first PSE device is adapted to provide power based on a) first power received from a first power source or b) second power received from a second PSE device via a first fire-resistant PoE connection () in case of emergency. The first PSE device is adapted to detect whether power is received from the second PSE device and to provide power to the emergency lighting device based on the second power via a second fire-resistant PoE connection (), if it has been detected that power has been received from the second PSE device. This can allow for a provision of PoE emergency lighting in case of fire, even if a communication via the fire-resistant PoE connections is not possible anymore.
