DIP Switch VLAN, Default and Extend
VLAN Its'the port isolation mode, so the PoE ports (1-24) of the switch cannot communicate with each other and can only communicate with the uplink port.
Default It's the normal mode, so all ports can communicate with each other and the transmission distance is within 100 meters as well as the transmission rate is 10/100M adaptive
Extend It's the link extension mode, so 1-24 ports PoE power supply and data transmission distance can be extended to 250 meters and the transmission rate becomes 10Mbps.
