A digital signal media conversion panel has a series of media converters for converting between electrical signals and fiber optic signals. The conversion panel includes a power feed for the media converters. Preferably the conversion panel includes some Power Over Ethernet receptacles thereby simplifying connection of devices such as Voice Over Internet Protocol telephones and security cameras. In this embodiment, a separate power adapter provides two voltages to the patent panel using the power feed. The use of a separate adaptor with two voltages simplifies the design and avoids heat problems.
