In this regard, FIG. 7 is an exemplary priority scheme for a power management scheme to provide sufficient power to power-consuming modules and PDs that may be powered by an RAU 14. In this example, RF communications services have been assigned higher priority than digital data services and powered ports. Thus, in this example, the available power on the power line 150 will be made available to the RF communications module 152. If more power is available from the power line 150 after power has been budgeted for the RF communications module 152, the remaining power is made available to the RXUs 160(1)-160(Z) to provide expansion RF communications services. If more power is available from the power line 150 after power has been budgeted for the RF communications module 152 and the RXUs 160(1)-160(Z), the remaining power is made available to the DDS module 154 to provide digital data services. If more power is available from the power line 150 after power has been budgeted for the RF communications module 152, the RXUs 160(1)-160(Z), and the DDS module 154, the remaining power is made available to the powered communications ports 158(1)-158(Q) to provide power to the PDs 156(1)-156(Q). Note that the priority schemed in FIG. 7 is exemplary and any other priority scheme desired could be implemented in a power management scheme.
