Function Features

• Powerful Stacking Capability

  It can form a virtual stack with up to 8 switches, and the total stacking capacity can reach 140.8 Gbps. The entire stack is managed through a single IP address, with redundant management paths. This stacking design not only expands the number of ports and overall network capacity but also simplifies network management, allowing administrators to operate multiple switches as a single device.

• Comprehensive Network Management Options

  It supports multiple management methods including SNMP, RMON, CLI and WebView GUI. Network administrators can choose the appropriate management interface according to their operational habits. The unified management mode of the stack and redundant management paths ensure that the switch can be configured, monitored and maintained efficiently and stably, which greatly reduces the difficulty of network management.

• Solid Network Security Mechanisms

  It implements IEEE 802.1x authentication and MAC address – based authentication to strictly control access to network devices and prevent unauthorized access. It supports IEEE 802.1q VLAN technology to divide the network into multiple logical segments, isolating traffic and reducing potential security risks. It also provides SSH v2 and SSL support to encrypt data during management and transmission, safeguarding the security of network management and data transmission processes.

• Reliable Traffic & Network Stability Control

  It uses IEEE 802.1p QoS technology to prioritize key business traffic, ensuring the stable operation of delay – sensitive and critical applications. The support for STP and RSTP protocols effectively prevents network loops and ensures the smoothness of redundant paths. It is also equipped with port mirroring and LAN View diagnostic functions, which facilitate administrators to troubleshoot network problems and ensure stable network operation.

• Practical Redundancy Design

  It adopts an optional redundant power supply unit configuration. When the main power supply fails, the backup power supply can take over immediately to avoid network outages caused by power problems. The combination of redundant management paths and stacking redundant designs further improves the overall availability of the network and ensures continuous network operation.

Application Scenarios

• Enterprise Office Networks

  It is suitable for medium and small – sized enterprises to build internal office networks. It can connect a large number of office devices such as computers, printers and IP phones. The stacking function allows the network to expand smoothly as the enterprise grows. The QoS function ensures the stable operation of important business applications such as video conferences and cloud office software, meeting the daily office data transmission and communication needs of enterprises.

• Campus Networks

  It can be deployed in universities, middle and primary schools and other educational institutions. It can connect teaching equipment in classrooms, computer labs, administrative buildings and other areas. The fiber ports ensure low – interference and stable data transmission in the large – coverage campus environment, and the simple management method is convenient for the school’s network management team to maintain the daily operation of the campus network and meet the needs of teaching, office and student daily network use.

• Industrial Automation Sites

  It is applicable to industrial fields such as manufacturing, petroleum and natural gas. It can connect industrial controllers, sensors, PLC devices and other equipment. Its resistance to electromagnetic interference and stable fiber transmission performance can adapt to the harsh industrial environment. It can realize reliable data collection and transmission between industrial control systems and support the normal operation of industrial automation production lines and remote monitoring systems.

• Remote Office and Branch Networks

  It can be used to build network infrastructures for enterprise branch offices and remote office locations. Its compact size and flexible port configuration are suitable for the limited space of branch offices. It can connect remote office devices to the enterprise’s core network through high – speed uplink ports. The stable connection performance and simple management mode ensure the efficient connection between remote teams and the headquarters, supporting the smooth development of remote office work.
