Does what it should. I had to replace an old switch that was unstable and changing cables or cables in / out did not recognize meht reliably in conjunction with a Fritz router, and no longer klarkam with my Heavy Duty HP LP with fixed IP and Power Save. This switch my network is again stable and performant. Execution is mE good old Netgear quality, ie massive construction metal. The power supply is dagen filigree, that here power is saved and there is work room capable. I could now trace why, but the investment has more than paid off from end user perspective.
