Claim Text:
1. An interface device for interfacing one or more external devices to Ethernet Power Source Equipment PSE, the interface device comprising: a network connection jack for connection to the PSE; a first output jack for providing an Ethernet power and data connection for an external device; a second output jack for providing a DC power connection for an external device; a power extractor circuit operatively connected to the network connection jack, for providing a signature to the PSE and receiving a power signal from the PSE, the power extractor circuit providing a predefined output signal in response to receiving a power signal from the PSE, wherein the power extractor circuit has an output connected to the second output jack, to provide the predefined output signal to the second output jack, the predefined output signal for powering an external device when the external device is connected to the second output jack; and at least one delay element having a control input connected to the output of the power extractor and arranged to electrically connect the network connection jack and the first output jack, after a predefined delay from a time at which the power extractor circuit provides the predefined output signal at the output of the power extractor circuit.
