    Please be more specific about your network topology. Did you connect all three ports of the TL-SG3210 to three ports of the same unmanaged switch?

    I discover a strange thing about this switch, i have a client with a small Zyxel 8 ports switch, when i connect this defective switch the ports vent down, so, i deduct, the problem can be from defective switches or routers, my network topology is now ;
    optical fiber on port 10 sfp, one 16 port gigabit switch on port 1, one switch 100 mb in port 3,
