As it should but sometimes does not. :-( In my case it was some OLD device, 10+ years old that never heard of a Gigabit interface and actually would even work on a 10Mbit port. This device will connect correctly on an older gigabit switch but NOT on a more modern Gigabit switch. :-( So I have : - A router - A POE switch for those devices that need POE - A normal Gigabit switch for all the other devices I have - An older switch to connect that one device that won't connect properly to the modern switch. :-( All witches are connected to the router, all devices connected to the switches. I could have bought a bigger POE switch but I already had the other switch(es) before I needed some POE ports. Bonno Bloksma
