I've got an unmanaged switch that is malfunctioning. Was working fine the other day, then we attached a device that was broadcasting over a segment of our LAN and basically disabled them with too much traffic. After we identified the culprit device, 2 of our 3 EF3124 starting working fine. The 3rd appears to be working, as far as what we see on the light display, but devices won't connect to the LAN. Is there a buffer that needs cleared or if I pull the power, do I need to wait a certain amount of time before I power it back up? I've only had the unit 2 months.
