| DIP Switch | Managed mode: Switches between managed and unmanaged mode. Managed mode includes local web management and cloud management. It is on by default. Extend mode: The transmission distance of ports 1–8 can reach up to 250 meters. The negotiation speed can be reduced to 10 Mbps. PoE Watchdog: Monitors the flow of data traffic for ports 1–8. If PoE fails for any of the ports and there is no traffic for 2 minutes, the failed ports will be restarted. |
