JetNet 5728G Series - Industrial Networking Solutions – Industrial Ethernet Switches and Routers

JetNet 5728G Series


JetNet 5728G-24P series is a rackmount High-Port Density and Gigabit Managed Industrial 24-port PoE switch, designed exclusively for highly critical and large-scale PoE applications such as real time IP video surveillance with high resolution quality and the evolving wireless communication systems such as Wimax and 802.11 a/b/g/n Access Points. 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 5ms 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 JetView Pro i2NMS 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.
