Centralized Power Management for Gigabit Ethernet PoE Networking
To facilitate 32W PoE power network applications with Gigabit speed transmission, the GSD-2022P is equipped with 16 10/100/1000BASE-T Gigabit Ethernet ports, 2 extra Gigabit TP ports and 2 1000BASE-X SFP interfaces with the inner power system. With a total of 185 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 GSD-2022P 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 Surveillance
The GSD-2022P brings you an ideally secure surveillance system at a lower total cost. The GSD-2022P provides 16 10/100/1000Mbps 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.
With this brand-new feature, the GSD-2022P provides an additional solution for 802.3at PoE+ distance extension, thus saving the cost of Ethernet cable installation.
Powered Device Alive Check
The GSD-2022P 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 GSD-2022P 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.
