This is an ethernet switch which allows you to extend your network with more network devices. It has 5 ports. You can plug any port in to your current router or switch, allowing you to connect another 4 devices. The lights at the front light up to show which port has a valid connection and then flash when data is being transferred. I've tested all 5 ports and all are working. It comes with little legs which can be used if want to stand the switch vertically. It includes the original netgear 12v power supply.
