4 PoE ports + uplink port + SFP port in a robust housing. What's not to like? Allows the use of redundant power supplies and has a normally open relay to monitor the status of the power supply (if one of the power supplies fails, the relay closes). It also has a special grounding lug. The top-hat rail installation works perfectly and without any problems. We use two MeanWell 48V/1.6A power supplies.
