The Ethernet switch includes 8 10/100Mbps Fast Ethernet ports with RJ-45 connectors and 32Gbps switch fabric to provide real time non-blocking transmission performance for satisfying the needs of high bandwidth data transmission requiring applications while ensuring traffic switching without data loss. Besides, the new system design includes a hardware based watchdog timer for keeping the operating system live. It also provides power redundancy with wide range DC10V~60V inputs for ensuring the power continuity in the system. Combining the outstanding L2 management features along with the LLDP and the Korenix NMS Intelligent NMS into the ruggedized design with IP31 enclosure and -25~70oC (JetNet 4508 V2) and -40~75oC (JetNet 4508-w V2) wide operating temperature, JetNet 4508 V2 switches provide highly reliable and secure data transmission under severe industrial environments.

High Performance Micro processor with embedded Hardware Watchdog Time The JetNet 4508 V2 designed with 32 bits ARM9E running at 180 MHz and with up to 200MIPS performance, combines an embedded hardware based watchdog timer to avoid system crashed by environmental factors, such as intense electromagnetic interference, extreme temperature variations and/ or any wrong instruction looping. This outstanding design can ensure the system stability and reliability when it installed in hardened environment. Advanced L2 Network Control Performance and Security features The JetNet 4508 V2 provides various...

In addition to all these management interfaces, JetNet 4508 V2 also supports Korenix View easy network management utility for achieving cost efficiency in system construction as well as the enhanced Korenix NMS, which integrates comprehensive network monitoring features for auto topology discovery, device auto discovery, group IP address change and firmware upgrade. Comprehensive Redundant Solutions - Multiple Super Ring (MSRtm) Industrial Intelligent NMS The JetNet 4508 V2 supports new generation ring technology - MSRTM (Multiple Super Ring), which includes various new technologies for different...

| Seamless Ring Port Restoration™ Seamless restoration is a new Korenix patented technology which can restore a failed ring without causing any loop problem, topology change and packet loss. With zero second restoration time, this mechanism eliminates any unstable status and guarantees the applications running non-stop. | Rapid Dual Homing (RDHTM) Technology Rapid Dual Homing is also an important feature of Korenix new generation Ring technology. It supports ring coupling with other vendors devices. Moreover, providing easy configuration and multiple redundancies, the failover time is much faster...

| TrunkRing™ TrunkRing is a new feature in MSR which merges the two technologies of RSR and link aggregation. It takes advantages of aggregation to enhance the link redundancy, while increasing the link speed. The ring will open only if all the aggregated links are broken. Link aggregation can be achieved by either static trunk or LACP. Not all the link sections in a TrunkRing need to be the same. Ring links can be either symmetric or asymmetric. Some are a single path, and the others are aggregated by links where the number of links in a trunk group can be different. Users can enhance the link...

Link Aggregation Control Protocol Link Aggregation Control Protocol allows users grouping multiple Ethernet ports in parallel to increase the link bandwidth. The aggregated ports can be viewed as one physical port, so that the bandwidth is higher than just one single Ethernet port. The member ports of the same trunk group can balance the loading and backup with each other. The LACP feature is usually used when higher bandwidth is needed for the backbone network. This is a cost-effective way for transferring much more Port Aggregation (Trunk) data. If the trunk port is also assigned as a ring...
