The present invention provides a system and method for prioritized application of operational power receiving over a data transmission cable. The system includes a primary component, at least one secondary component, and a power supply. The system further includes a data transmission cable for transmitting operational power from the power supply to the primary component and the at least one secondary component, and for transmitting data between the primary component and a remote station. The system further includes a splitter for separating the operational power from the data received over the data transmission cable, and prioritizing delivery of the operational power to the primary component and the at least one secondary component, wherein at least a threshold level of power is delivered to the primary component, and available operational power in excess of the threshold level is delivered to the at least one secondary component.
