Abstract
The present invention relates to fast start-up of powered devices () connected to a power sourcing equipment (') in a Power over Ethernet system (). A stored voltage-current profile of an initial powering phase of a powered device () is provided. A voltage level provided to the powered device () in a subsequent initial powering phase of the powered device () is adjusted as long as a value corresponding to a current voltage level of a voltage-current profile of the subsequent initial powering phase deviates less than a predetermined threshold level from its corresponding value of the stored voltage-current profile of the initial powering phase of the powered device () and until a predetermined voltage level is reached. This can allow detecting whether a previously connected powered device () was replaced by another powered device () and to immediately start-up an unchanged powered device () with previously used operation parameters.
