Industrial Ethernet Switch – JetNet 4508

Industrial ethernet switch JetNet-4508v2


The JetNet 4508 V2 is an 8-port industrial managed Fast Ethernet Switch designed with advanced Layer 2 management features and high system reliability, including MSR and MSTP network redundancy technologies, for ensuring real-time and high quality connectivity in various networking applications. 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 JetView Pro 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.
