Abstract
A method of determining an effective resistance between a power sourcing equipment and a powered device, the powered device exhibiting an interface and an operational circuitry, the method comprising: prior to connecting power to the operational circuitry of the powered device, impressing two disparate current flow levels (I, I) between the power sourcing equipment and the powered device; measuring the voltage at the powered device interface (V, V) responsive to each of the impressed disparate current levels; measuring the voltage at the power sourcing equipment (V, V) responsive to each of the impressed disparate current levels; and determining the effective resistance between the power sourcing equipment and the powered device responsive to the V, V, V, V, Iand 1.
