Working Principle

1. Data Receiving Stage: When data packets transmitted from terminal equipment arrive at the RJ45 copper port or SFP+ fiber port, the port physical layer transceiver chip completes analog electrical signal or optical signal demodulation, converts external transmission signals into digital bit stream data recognizable by the internal switching chip, then transmits the complete data packet into the shared dynamic packet buffer memory for temporary storage.
2. Data Processing Stage: The core ASIC switching chip extracts key identification fields from the data packet header, including source MAC address, destination MAC address, VLAN tag label, source and destination IP address, transmission layer port number and priority tag information. The chip searches the pre-stored MAC address table, VLAN resource table and static routing table stored in on-board flash memory to match forwarding rules, simultaneously executes pre-configured ACL filtering, QoS priority marking, broadcast storm suppression and port security access control logic, discards illegal data packets that do not meet access rules directly in the buffer memory without subsequent forwarding processing.
3. Data Forwarding Stage: For legal data packets passing all security and filtering rule checks, the switching chip determines the target physical output port according to the matched MAC address table or inter-VLAN routing table entry; if the destination MAC address entry does not exist in the MAC address table, the chip executes broadcast forwarding operation and copies the data packet to all ports belonging to the same VLAN segment. During forwarding scheduling, the chip distributes data packets to 8 hardware priority queues corresponding to the target port, and allocates transmission time slices according to pre-configured strict priority or weighted round-robin QoS scheduling algorithm to realize differentiated priority transmission of different service data streams.
4. Data Output Stage: The port physical layer transceiver chip reads data packets from the corresponding priority queue buffer memory, completes digital bit stream modulation into electrical signals (copper ports) or optical signals (fiber ports), then transmits the modulated signal data packets outwards through connected network cables or fiber jumpers to the target receiving terminal equipment.

   During the entire continuous working cycle, the main control CPU on the switching motherboard operates independently in parallel with the ASIC forwarding chip, responsible for receiving remote management configuration commands, updating MAC address tables and routing tables, recording system running logs and fault alarm information, detecting hardware port status changes, and executing firmware upgrade and system configuration backup tasks, ensuring coordinated operation of high-speed hardware packet forwarding and flexible equipment software management functions.

Use Precautions

Power Supply Usage Precautions

1. Only connect the equipment power input socket to standard mains power sockets with complete grounding protection; do not use ungrounded extension cords or damaged power cables to supply power to the switch, avoid electric shock hazards and static damage to internal chips
2. The equipment supports wide-range AC input, but frequent severe voltage fluctuation and instantaneous power surge will cause abnormal restart of the switch; install dedicated surge protection power strips or industrial power supply filters at the front end of the power input circuit in industrial power supply environments with unstable voltage
3. Cut off the power supply completely before disassembling the equipment shell, replacing internal components or plugging/unplugging chassis blade modules; do not hot-plug the power input cable during normal equipment operation to prevent instantaneous power failure from damaging the flash memory storage chip and causing loss of equipment configuration files

Daily Operation & Wiring Precautions

1. Regularly check the front panel LED status indicators during daily equipment operation; if the fault alarm LED is continuously lit, cut off non-critical terminal port connections in time, export system running logs for fault analysis, and eliminate abnormal traffic sources causing equipment alarms
2. Do not plug or unplug network cables and fiber jumpers violently during equipment power-on operation; excessive pulling force will damage internal port elastic contact pieces and fiber core wires, leading to poor contact and intermittent data packet loss faults
3. Keep the equipment installation environment dry and clean; avoid installing the switch in locations with high humidity, corrosive chemical gas, large amounts of floating dust or direct liquid splashing risks, prevent internal circuit board short-circuit and metal component oxidation corrosion damage
4. Do not place heavy objects on the top surface of the equipment shell; excessive external pressure will deform the metal casing, squeeze internal circuit boards and chip components, causing circuit disconnection and permanent hardware damage

Maintenance & Upgrade Precautions

1. Execute complete configuration file backup operation before all firmware version upgrade and equipment configuration modification operations, store backup configuration files in local offline storage equipment, to realize rapid configuration recovery if upgrade failure or configuration error occurs and causes equipment abnormal operation
2. Firmware upgrade transmission must adopt stable wired local console port transmission or TFTP wired network transmission mode; wireless Wi-Fi transmission is prohibited for firmware upgrade file delivery, unstable wireless signal will cause incomplete firmware file transmission, leading to equipment boot failure and bricking fault
3. Do not open the equipment metal shell for internal disassembly maintenance without professional industrial network equipment maintenance qualification; the internal circuit board contains high-voltage power conversion circuits and precision electrostatic-sensitive chips, unauthorized disassembly will cause electric shock hazards and permanent static breakdown damage to core components, and will void all original equipment manufacturer product warranty service rights
4. Conduct regular quarterly equipment maintenance inspections: clean dust accumulated on front panel ports and shell heat dissipation fins with dry anti-static soft brushes, check the tightness of all wiring connectors and cabinet grounding wire connections, verify the normal lighting status of all port LED indicators, and clear redundant historical log files stored in equipment flash memory to avoid insufficient storage space affecting normal system operation
