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 Centralized Power Management for Gigabit Ethernet PoE NetworkinTo facilitate 30W PoE power network applications with Gigabit speed transmission, PLANET GSW-1820HP is equipped with 16 10/100/1000BASE-T Gigabit Ethernet ports and 2 1000BASE-X SFP interfaces with the inner power system. With a total of 250 watts of PoE budget, it features high-performance Gigabit IEEE 802.3af PoE (up to 15.4W) and IEEE 802.3at PoE+ (up to 30W) capabilities on all ports. By offering reliable switching technology and advanced networking features, the GSW-1820HP optimizes the installation and power management of network devices such as wireless access points, VoIP phones, and security cameras. It also eliminates time and cost of deployment by integrating power and data switching into one unit and freeing network devices from restrictions of power outlet locations and the additional AC wiring. Perfect Integrated Solution for PoE IP SurveillanceThe GSW-1820HP brings an ideal secure surveillance system at a lower total cost. The GSW-1820HP provides 16 10/100/1000Mbps 802.3at PoE+ ports able to feed sufficient PoE power for 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 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 sitesEthernet Data Transmission Distance ExtensionThe DIP switch provides “Standard”, “VLAN” and “Extend” operation modes. - The GSW-1820HP operates as a normal IEEE 802.3at PoE+ switch in the “Standard” operation mode. - The “VLAN” operation mode features with 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 GSW-1820HP operates on a per-port basis at 10Mbps duplex operation but supports 25-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 GSW-1820HP provides an additional solution for 802.3at PoE+ distance extension, thus saving the cost of Ethernet cable installation.Intelligent Powered Device Alive CheckThe GSW-1820HP can monitor connected PD status in real time via PD alive check function. Once the PD stops working and responding, the GSW-1820HP will resume the PoE power and bring the PD back to work. It will greatly enhance the network reliability through the PoE port resetting the PD’s power source and reducing administrator management burden.Energy-saving DesignThe GSW-1820HP uses new engine that incorporates two advanced Green Networking technologies:- Idle Mode Link Down power savings- Intelligent Scales Power based on cable length The Idle mode Link Down power savings of the GSW-1820HP complies with IEEE 802.3az Energy Efficient Ethernet (EEE) standard to automatically lower power for a given port when it is not linked. The Intelligent Scales Power technology actively determines the appropriate power level based on the cable length. When connecting to the GSW-1820HP with Ethernet cable shorter than 20m, a device can obtain maximum power savings because the GSW-1820HP would automatically detect the Ethernet
