Abstract

A method and apparatus are disclosed for distributing power in a media converter system. The method involves converting an input voltage to an intermediate voltage and transmitting the intermediate voltage to a downstream converter. The downstream converter converts the intermediate voltage to a usable output voltage that is supplied to the media converter ports. The apparatus includes a main power supply for creating the intermediate voltage and downstream converters located remotely from the main power supply for converting the intermediate voltage to the usable output voltage. Transmission cables are also included for providing the intermediate voltage to the downstream converters. The apparatus may also include a bus with connections for the power supply and a power distribution module. The power supply and power distribution module utilize identical connections thereby providing flexibility in positioning the power supply and distribution module in a chassis.
