Each of at least two of the shelf-mountable electrical systems includes one or more chassis, shelf computing devices, a shelf power supply mechanism, and one or more power-pooling bus elements. The control circuit includes a voltage control loop and a current control loop, and the control circuit uses the voltage control loop to provide voltage mode control if the output current signal is greater than or equal to the nominal current and less than the maximum current, wherein the output power is substantially constant. If any of the television channels identified is a likely identifiable channel and is designated by approximately half of the available television lineups, available television lineups may be deleted based on the television signal received by the selected tuner position. The repeater is coupled to the auxiliary communication channel and passively captures configuration data from the auxiliary communication channel.
