3. Working Principle

1. Equipment Initialization & Parameter ConfigurationAfter power-on, the switch automatically completes self-inspection and system initialization to check the operating status of ports, power interfaces, data forwarding units and management units, and enters ready state after confirming normal conditions. Administrators configure network parameters including VLAN settings, QoS priorities, ACL rules, virtual switch bonding and port speed via Micro-USB ports, network management software or command line interfaces to complete network adaptation.
2. Device Access & MAC Address LearningTerminals, servers and industrial control devices are connected to RJ45 or SFP+ ports via network cables or optical modules. The switch automatically identifies accessed devices, learns and records their MAC addresses and updates information into the local MAC address table, providing accurate basis for fast packet forwarding and target device positioning.

1. Data Forwarding & Traffic OptimizationUpon receiving data packets, the switch parses destination MAC addresses or IP addresses, matches them with local MAC address tables and routing tables, and forwards packets accurately to target devices or uplink networks. Meanwhile, QoS mechanism classifies network traffic by priority to prioritize audio, video, real-time control data and core service data, ensuring stable transmission of key applications and preventing network congestion.

1. Security Protection & Redundancy GuaranteeThe switch divides the entire network into multiple logical subnets via VLAN to realize subnet isolation and improve network security. ACL policies, port security and MAC address filtering block illegal device access and resist network attacks. Redundant power supply enables automatic power switching to avoid network shutdown during main power failure. Distributed module independent operation ensures that single-module faults will not affect overall network operation and greatly improves network fault tolerance.
2. Status Monitoring & Fault HandlingThe switch monitors real-time operating status including power supply, ports, data forwarding and module running conditions as well as network connection status, and displays working conditions through built-in indicators. Once port faults, power anomalies, transmission errors and module failures are detected, it will trigger alarms and upload fault information to network management terminals for rapid troubleshooting and stable network operation.
