Abstract
A powered device receives electrical power through a data transmission cable from a power supplying device that monitors a load on the data transmission cable and turns off the power to the load if the load is outside of a range. The powered device draws a first current at least part of a time during which the powered device is in a low power mode. The powered device is operable during the low power mode to draw a second current. And the powered device increases and decreases the second current to maintain a sum of the first current and the second current, or a level of a current into the powered device, at least at a minimum level for at least a portion of a cycle time.
