16-Port 10/100/1000T 802.3at PoE + 2-Port 1000X SFP Switch PLANET GSW-1820HP
– Support 16-port 10/100/1000BASE-T Gigabit RJ45 copper with 802.3at PoE+ injector function and 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
