Centralized Power Management for Gigabit Ethernet PoE Networking To facilitate 32W PoE power network applications with Gigabit speed transmission, PLANET GSW-2824P is equipped with 24 10/100/1000BASE-T Gigabit Ethernet ports, 2 extra Gigabit TP ports and 2 1000BASE-X SFP combo 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 32W) capabilities on all ports.
By offering reliable switching technology and advanced networking features, the GSW-2824P 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.
Ethernet Data Transmission Distance Extension The DIP switch provides “Standard”, “VLAN” and “Extend” operation modes. The GSW-2824P 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 GSW-2824P 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 GSW-2824P provides an additional solution for 802.3at PoE+ distance extension, thus saving the cost of Ethernet cable installation.
Powered Device Alive Check The GSW-2824P 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.
