What can I say, a plug and play device that does everything it promises. Nonblocking and fanless - unbelievable that it is possible to operate 32Gbps backplane without a fan. That alone rewrites sufficiently energy efficiency that brings this switch (all ports have occupied and the switch eats only 8 watts). Super is also the integrated power supply and the IEC connector - makes together with the metal housing a very sophisticated look. Rack Mount Kit for 10 "cabinets can easily be produced with a Dremel even when the supplied 19" abused angle. From me an absolute recommendation!
