Incredibly easy way to get another 4x gigabit ports.
Incredibly easy solution! Just plug it in... and you have now another 4 gigabit ports to use. No configuration, that's it... what more can I say about functionality? There are a couple of different versions physically however, this one is steel bodied and has metal ports. There other is just about all plastic, it does the same job... but not as robust (I was gifted one of those by my son after ordering this one). I thought the metal version would dissipate heat better, but neither is much above room temperature in my application.
