Description
GSW-1820HP
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 mini-GBIC/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 52V 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 desktop size, 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
