  Power over Ethernet:
  Complies with IEEE 802.3at Power over Ethernet end-span PSE
  Up to 16 ports of IEEE 802.3af/802.3at devices powered (ports 1~16)
  Supports PoE power up to 32 watts for each PoE port, with a total PoE budget of 185W.
  Each port supports 54V DC power to PoE powered device
  Auto detects powered device (PD)
  Supports PD alive function
  Circuit protection prevents power interference between ports
  Remote power feeding up to 100m in standard mode with 250m in extend mode
   
  Switching:
  Hardware-based 10/100/1000Mbps auto-negotiation and auto MDI/MDI-X
  Supports IEEE 802.3x flow control in full-duplex mode and backpressure in half-duplex mode
  Integrates address look-up engine, supporting 8K absolute MAC addresses
  9K jumbo frame supports all speeds (10/100/1000Mbps)
  Hardware DIP switch for Standard, VLAN and Extend mode selection; 
  VLAN mode: Ports 1 to 16 cannot communicate with each other, but can communicate with the uplink ports 17 to 18 and SFP ports 19 to 20
  Extend mode: Ports1 to 8 have data rate of 10Mbps. The farthest transmission distance of up to 250 meters and all ports can communicate with each other.
  VLAN mode is to isolate ports to prevent broadcast storm and defend DHCP spoofing
  Automatic address learning and address aging
  Supports Energy-Efficient Ethernet (EEE) function (IEEE 802.3az)
