These came from a local university when they upgraded their equipment. They've been tested and work properly. You will receive exactly what is in the listing's pics and everything that is on the switch...2 power supplies, extra modules, ports, etc. They are also all in good condition and look like the one in the listing's pics, bc I grabbed one at random. (I got a lot of these, so I am selling them cheap).
