I'm slightly interested in the DIN rail mounted managed switch. I have an application right now with underground fiber running to an electrical cabinet on the other side of a parking lot where I need to locate a PoE switch to power an IP based access control keypad and a few cameras, and tag the IP readers port. I have bought a SG300-8MPP for this, but it's larger than I would like and I'm going to have to devise a good mount for it. I'd buy one to try out, but this isn't the best application to find out if a switch is unreliable or not.
