I am having issue with 08H20G4-48P lately. After a few power outages the switch does not forward any traffic. I can access it remotely via Web GUI and via ssh without any problem. But I can't access any other devices that are connected to it. Also the connected devices can't access beyond it. Rebooting it via cli or powering off/on it solves the problem.
What should be the problem? It has latest available firmware installed.
