18-Port GE + 2-Port 1000X SFP PoE Desktop Switch PLANET GSD-2022P
– Support 16-port 10/100/1000BASE-T Gigabit RJ45 copper with IEEE 802.3at PoE+ injector function, 2 10/100/1000BASE-T Gigabit RJ45 copper interfaces and 2 1000BASE-X SFP interfaces.
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).
Hardware
– 12-inch desktop size, 1U height.
– LED indicators for system power, per port PoE ready and PoE activity, speed, Link/Act.
– 1 silent fan to provide stable and efficient power performance.
– Supports contact discharge of ±6KV DC and air distance discharge of ±8KV DC for Ethernet ESD protection.
– Supports ±6KV surge immunity.
