I bought this little switch to expand my home LAN. There is no really setup, just plugged it to one of my router's ports, hooked up the power supply and it was ready to go. It's eight ports are great, you can use any one as the up-link without any special configuration. I am using six out of its eight ports, one for up-link and the others for attached devices. It perfectly detects the speed each device is capable to achieve and the LED's illuminated accordingly. It is very well build, has a solid and durable feeling. No complains, at all. 

Question: What happens to the ports if you plug it in?
Answer: It perfectly detects the speed each device is capable to achieve and the LED 's illuminated accordingly
