All of the 24 Fast Ethernet PoE injector ports of the switch can deliver 15.4W by IEEE 802.3af or 30W by the latest High Power PoE IEEE 802.3at standard. The switch generates up to 540W total power budget in DC power mode and 240W in AC power input mode for upgrading the existing video network infrastructure to a powerful surveillance network. The 4 Gigabit Ethernet ports provide high speed uplink to connect with higher level backbone switches. With the Korenix patented MSRtm network redundancy technology, the switches can aggregate up to 12 Fast Ethernet and 2 gigabit rings while providing high quality data transmission with less than 10ms network recovery time. Furthermore, to ensure the traffic switching without data loss and blocking, the JetNet 5728G-24P provides backplane with the integrated non-blocking switching function. JetNet 5728G-24P incorporates LLDP function and perfectly works with the Korenix patented Korenix NMS for allowing administrators to automatically discover devices and efficiently manage the industrial network performance in large scale surveillance networks. To further ensure the non-stop power delivery, JetNet 5728G-24P supports dual 48VDC power inputs and provides alarm relay output signaling function. For high voltage requiring applications the PoE switch provides extra 90~264VAC or 127~370VDC power supply capability. With the advanced Layer2 management features including IGMP Query/Snooping, DHCP, 256 VLAN, QoS, LACP, LPLD, etc. and the corrosion resistant robust design, JetNet 5728G-24P highly outstands from other PoE switches and becomes the revolutionary solution for industrial surveillance applications.

Petrol Stations Airports Since the ratification of the PoE standard in 2003, the Power over Ethernet technology becomes a trend; more devices adopt PD technology to obtain power through Ethernet cable eliminating the need of running separate power wirings to a remote device. In this regard, the IEEE 802.3af PoE standard with 15.4W power budget already satisfies the power needs of most applications, such as 802.11 a/b /g /n wireless AP for Hot-Spots, Airport Terminations etc. However, it cannot satisfy the power needs of high-end demanding applications, such as WiMAX, IP DOM Cameras, which require...

100M Max > 12.5R max > 7.5V max Dropout CATSe/CAT6 Diagram: PSE Power Mechanism ◄ Industrial PoE / PoE Plus Switch IEEE 802.3at LLDP Power over Ethernet JetNet 5728G-24P series implements the Link Layer Discovery Protocol (LLDP) PoE into the system for efficient power budget negotiation between PSE and PD devices. The LLDP packet provides smart power budget control behavior to fulfill the needs of higher end setups requiring exact high power delivery. By using the ongoing dynamic re-negotiation function of the IEEE802.3at LLDP PoE, the JetNet 5728G-24P can perform more intelligently by dynamically...

| Up to 9KBytes Jumbo Frame The typical Ethernet frame ranges from 64 to 1518 bytes, which is only sufficient for general usage. Contrary, in large scale surveillance networks, where users need to transmit large video streams, the files may be divided into many small size packets. While the transmitting speed becomes slow, 9KBytes Jumbo frame can solve the issue. Korenix JetNet 5728G-24P supports Jumbo Frame to enhance the network communication while allowing users to easily transmit up to 9K Jumbo Frame packet.
