The JetNet 4508 V2 series support layer2 management functions, including the LLDP and the Korenix patented JetView Pro i2NMS for efficient network management and auto topology visualization, the IEEE 1588 PTP for precise time synchronization, VLAN / Private VLAN and QinQ for enhanced data transmission security and easy network segmentation, and many others. For achieving high network reliability, the switches in addition to RSTP and MSTP, also support Korenix’s MSR network redundancy technology as well as the MultiRing, which allows aggregating up to 4 rings within a switch and where the network redundancy is less than 5ms.
The JetNet 4508 V2 switches are designed with 8 Fast Ethernet ports with 32Gbps switch fabric to provide real time non blocking data transmission without data loss. The 2 out of the 8 Fast Ethernet ports of the JetNet 4508f V2 model are optical fiber, designed to provide real time data transmission for achieving longer distances.
To provide system stability and reliability in harsh environments, the switches further incorporate the built-in watchdog timer, which helps to avoid system crash caused by environmental factors, such as intense electromagnetic interference, wide temperature ranges, etc...
Last but not least, the new superior system design of the managed switches also provides a wider range of dual DC10V~60V inputs with redundancy for ensuring the fail-safe power supply in the system. Combining the outstanding L2 management features into the ruggedized design with IP31 enclosure and -25~70°C (JetNet 4508 V2), -10~70°C (JetNet 4508f V2) and -40~75°C (JetNet 4508-w V2) wide operating temperature, JetNet 4508 V2 switches provide highly reliable and secure data transmission under severe industrial environments.
