A wireless access device in a local area network having a plurality of transceivers. The mounting bracket includes a plurality of pins extending outwardly therefrom. Furthermore, the invention gives a cell a number indicating the order in which said cell has been inputted from each of the input ports including the high-speed input port and corrects the order of the cells outputted from the output buffers into the order in which they have been inputted, on the basis of the numbers added to the cells. A disconnection module disconnects at least one of the two or more redundant power supplies from the one or more power sources in response to the load module determining that the load of the electronic device is operating at a power level below the predetermined power threshold.
