8 X MicroUSB to ethernet PCB design

The project is to build a very small micro usb to ethernet bored for cluster computer . Each usb device will have is own usb to ethernet chip on the board. Which in turn will connect to a network switch jet the board will also need to provide power via a separate usb connector 1 each device. In addition the board will need a single power connector and an rj45 connector so that the board can be connected to an external network. A block diagram will be provided showing what is required . The output required will need to be a file to be uploaded to an online bored manufacturer .
