Technical Specifications
Ordering Information

TNM4000 Modular BackBone Switch the chassis of which is standard 19-inch rack-mount, 4U high, with 10 slots, including 7 service slots + 2 power slots + 1 manage slot, supporting 72 service ports at most. and all the modules support online upgrade. All models of TNM4000 series are equipped with unified optical modules and operating system software, forming a system that can adapt to future development. Due to the operating consistency, the utilization is greatly improved as well. With hardware-based algorithm, the patented MRD-Ring® (MRDcom Real-Time Ring) technology ensures less than 5ms self-recovery time of every node and less than 50ms self-recovery time of the network.

TNM4000 also supports standard xSTP Protocol which can constitute a redundant structure with different product manufacturer and ensure their own high-speed self-healing function. The high backplane capacity and a variety of interface modules can ensure fast and efficient exchange and routing of Layer 2 network traffic. Its PTN-based modules can support applications based on packet switching services.TNM4000 have high stability and reliability, and various key operating parameters can be monitored locally and remotely. Advanced solution, extended industrial design, and patented technologies make TNM4000 one of the top choices for harsh industrial environments.
