GSW-1820HP 16-Port 10/100/1000T 802.3at PoE + 2-Port 1000X SFP Gigabit Ethernet Switch

16-Port 10/100/1000T 802.3at PoE + 2-Port 1000X SFP Gigabit Ethernet Switch

Physical Port

• 16-port 10/100/1000BASE-T Gigabit RJ45 copper with 802.3at PoE+ injector function
• 2 1000BASE-X SFP slots

Power over Ethernet

• Complies with IEEE 802.3af/at Power over Ethernet end-span PSE
• Up to 16 ports of IEEE 802.3af/802.3at devices powered
• Supports PoE power up to 30 watts for each PoE port, all power up to 240W PoE budget.
• Each port supports 54V DC power to PoE powered device
• Auto detects powered device (PD)
• Circuit protection prevents power interference between ports
• Remote power feeding up to 100m

Switching

• Hardware-based 10/100/1000Mbps auto-negotiation and auto MDI/MDI-X
• Flow control for full duplex operation and back pressure for half duplex operation
• Integrates address look-up engine, supporting 8K absolute MAC addresses
• 9K jumbo frame supports all speeds (10/100/1000Mbps)
• IEEE 802.1Q VLAN transparency
• Hardware DIP switch for Standard, VLAN and Extend mode selection;
  • VLAN mode: Ports 1 to 14 cannot communicate with each other, but can communicate with the uplink ports 15 to 16 and SFP ports 17 to 18
  • Extend mode: Ports1 to 8 have data rate of 10Mbps. The farthest transmission distance up to 250 meters and all ports can communicate with each other.
• The DIP switch can 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)

Hardware

• 19-inch metal housing, 1U height
• LED indicators for PoE ready and PoE activity
• Ethernet Link Energy-saving technology
  • Link down power savings
  • Intelligent use of power based on cable length
