Cost-optimized, Multi-mode Ethernet Switch for PoE Networking To facilitate 32W PoE power network applications with the transmission, PLANET FGSD-2621P is equipped with 24 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-2621P 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-2621P brings you an ideally secure surveillance system at a lower total cost. The FGSD-2621P provides 24 10/100Mbps 802.3at PoE+ ports able to feed sufficient PoE power to 24 IEEE 802.3af/IEEE 802.3at PoE+ IP cameras at the same time. It is also able to connect with one 24-channel NVR or three 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-2621P 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-2621P 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-2621P provides an additional solution for 802.3at PoE+ distance extension, thus saving the cost of Ethernet cable installation.       Powered Device Alive Check The FGSD-2621P 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-2621P 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 20/40/80/120 kilometers (single-mode fiber or WDM fiber). They are well suited for applications within the enterprise data centers and distributions.
