The TNM4000 rack-mount 28-port Layer-2 industrial switch is widely used in transportation, energy and industrial control. All models share a unified OS for a future-oriented standardized architecture that improves utilization through consistent operations. Beyond stable, reliable, secure high-performance services, it offers flow analysis, policy-based QoS and controllable multicast optimization, with high bandwidth, VLAN support and easy maintenance for large industrial networks.
The TNM4000 general-purpose managed rack-mount industrial switch is fanless with redundant dual power inputs to avoid fan-failure risks and keep running if one PSU fails, greatly improving reliability and continuity. It supports redundant rings (ERPS, MRP, etc.) and RSTP/STP for fast network fault recovery and high backbone availability.
The TNM4000 general-purpose managed rack-mount industrial switch supports wide operating temperature -40°C ~ +85°C with strong environmental adaptability, shock and EMI immunity for power, transportation, oil and chemical industries.
The cable is connected, but the port will not come UP / the link is down. What should I check?
+What are the PoE power specifications?
+Which ring protocols are supported, and what is the self-healing time?
+How should I choose between Layer-2 and Layer-3 industrial switches?
+Can non-OEM SFP optical modules work normally?
+How do I restore factory settings if I forget the device login password?
+What are the power supply requirements for industrial switches?
+What are the operating temperature range and protection rating of industrial switches?
