COMMUNICATION DEVICE AND ELECTRIC BOARD COMPRISING SUCH A DEVICE

摘要

The invention relates to an electric board including at least one tray (1) which can be withdrawn and which forms a recess for positioning an electric device, characterized in that the board includes an Ethernet high-frequency-communication device forming a communication daisy chain (30), in that said at least one tray (1) includes a connector (5) that can be withdrawn so as to be connected or disconnected to/from the communication chain (30), in that said at least one tray (1) can assume a first plugged-in position, in which the tray is connected to the communication chain, and in that the tray includes a switch controlling a bypass switch so as to form a bypass (32) on the communication chain (30) when the tray (1) is assuming a second unplugged position.
