Planet 16-Port 10/100TX 802.3at PoE + 2-Port 10/100/1000T + 1-Port Shared 1000X SFP Desktop Switch (185 Watts) | FGSD-1821P

Cost-optimized, Multi-mode Ethernet Switch for PoE Networking
To facilitate 32W PoE power network applications with the transmission, PLANET FGSD-1821P is equipped with 16 10/100BASE-TX Fast Ethernet ports, 2 extra Gigabit TP ports and 1 1000BASE-X SFP combo interface ideally suitable for centralized power management. With a total of 185 watts of PoE budget, it features high-performance Gigabit uplink and IEEE 802.3at PoE+ (up to 32W) capabilities.

Two Gigabit Uplink Ports
The FGSD-1821P provides two extra Gigabit TP ports and one 1000BASE-X SFP combo interface  that enable the network administrators to increase their network bandwidth to relieve traffic congestion when the two 10/100/1000BASE-T or one 1000BASE-X uplink port are used to connect devices, such as NVR, video streaming server, NAS and more. With the combo design, the administrators can easily connect network devices no matter how large the network expansion is.

Perfect Integrated Solution for PoE IP Surveillance
The FGSD-1821P brings you an ideally secure surveillance system at a lower total cost. The FGSD-1821P provides 16 10/100Mbps 802.3at PoE+ ports able to feed sufficient PoE power to 16 IEEE 802.3af/IEEE 802.3at PoE+ IP cameras at the same time. It is also able to connect with one 16-channel NVR or two 8-channel NVRs, uplinked to backbone switch and the monitoring center. With such a high-performance switch architecture, the recorded video files from the PoE IP cameras can be saved to the NVR system where the administrator can control and monitor the surveillance images in both the local LAN and remote sites.

Ethernet Data Transmission Distance Extension
The DIP switch provides “Standard”, “VLAN” and “Extend” operation modes. 

The FGSD-1821P operates as a normal IEEE 802.3at PoE+ switch in the “Standard” operation mode. 
The “VLAN” operation mode features port-based VLAN function that helps to prevent the IP camera’s multicast or broadcast storm from influencing each other.
In the “Extend” operation mode, the FGSD-1821P operates on a per-port basis at 10Mbps duplex operation but supports 20-watt PoE power output over a distance of up to 250 meters overcoming the 100m limit on Ethernet UTP cable. 
 
With this brand-new feature, the FGSD-1821P provides an additional solution for 802.3at PoE+ distance extension, thus saving the cost of Ethernet cable installation.

Powered Device Alive Check
The FGSD-1821P adopts not only Power over Ethernet technology, but also automated PD monitoring and real-time PoE status.

The PD alive check feature is applied in Standard, VLAN and Extend modes. After the PoE of the port is powered on, the device starts to detect whether the port is transmitting data. If the port does not transmit data and the duration exceeds a specific time, PoE will automatically power off and then re-power. It also will greatly enhance the network reliability in that the PoE port will reset the PD power, thus reducing administrator’s management burden.

Flexible Extension Solution
The two mini-GBIC slots built in the FGSD-1821P are compatible with the 1000BASE-SX/LX SFP (Small Form-factor Pluggable) fiber transceiver, uplinked to backbone switch and monitoring center in long distance. The distance can be extended from 550 meters (multi-mode fiber) to 10/20/30/40/50/60/70/120 kilometers (single-mode fiber or WDM fiber). They are well suited for applications within the enterprise data centers and distributions.

Applications

Perfectly Integrated Solution for IP PoE Camera and NVR System
Particularly designed for the growing popular IP Surveillance applications, the FGSD-1821P 802.3at PoE Switch is positioned as a Surveillance Switch for quick and easy PoE IP camera deployment with power feeding. The FGSD-1821P provides both 802.3at and 802.3af PoE functions along with 16 10/100BASE-TX ports featuring 30-watt 802.3at or 15.4-watt 802.3af PoE in RJ45 interface, 2 extra Gigabit copper ports and 1 Gigabit SFP uplink interfaces supporting high-speed transmission of surveillance images and videos.

Department / Workgroup PoE Network
Providing 16 PoE in-line power interfaces, the FGSD-1821P can easily build a power that can centrally control IP phone system, IP camera system and wireless AP group for the enterprise. Cameras can be installed around the corner in the company or campus for surveillance demands. Without the power-socket limitation, the FGSD-1821P makes the installation of cameras easier and more efficient.
