| LED | PWR(power supply),SW(DIP),1-27 Green(Link&Data) | 
| 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. |
