Product Description

28-port full gigabit layer 2 managed rack mounting industrial Ethernet switch


IES5028G-4GS-8GC-16GT is 28-port full Gigabit layer 2 managed industrial Ethernet switches. It provides Gigabit copper port, Gigabit combo port, Gigabit SFP slot and adopts 1U rack mounting. Abundant interface number and full Gigabit bandwidth can meet the application requirements of large-scale industrial networks.


Network management system supports various network protocols and industrial standards, such as STP/RSTP/MSTP, 802.1Q VLAN, QoS, IGMP Static Multicast, LLDP, Port Trunking, Port Mirroring, etc. It also possesses complete management functions, including Port Configuration, Port Statistics, Access Control, 802.1X Authentication, Network Diagnosis, Rapid Configuration, Online Upgrading and so on, and supports CLI, WEB, Telnet, SNMP and other access methods. It can provide users with good experience with friendly design of network management system interface, simple and convenient operation.


Power supply input is two independent power supply circuits, which can ensure the device normal operation when one of the power supplies breaks down. When power supply or port link failure occurs, ALARM indicator will be bright and send out alarm, meanwhile, alarm device connected to the relay will send out alarm for rapid scene troubleshooting. Hardware adopts fanless, low power consumption, wide temperature and voltage design and has passed rigorous industrial standard tests, which can suit for the industrial scene environment with harsh requirements for EMC. It can be widely used in smart grid, rail transit, smart city, safety city, new energy, aerospace, intelligent manufacturing, military project and other industrial fields.


Features and Benefits

  • User password can conduct user hierarchical management to improve the device management security
  • Anti-attack control, ACL and 802.1X authentication can enhance the network flexibility and security
  • E-mail alarm is convenient for immediate fault discovery during remote management
  • Relay alarm is convenient for troubleshooting of construction site
  • Storm suppression can restrain the broadcast, unknown multicast and unknown unicast
  • SSHD configuration can achieve data transmission encryption, preventing DNS and IP spoofing
  • TELNET and HTTPS configuration can guarantee the data access security
  • VLAN is used for simplifying network planning
  • Port trunking and LACP can increase network bandwidth and enhance the reliability of network connection to achieve optimum bandwidth utilization
  • IGMP Snooping, GMRP and static multicast can be used for filtering multicast traffic to save the network bandwidth
  • Support Port Isolation in the same VLAN
  • SW-Ring and STP/RSTP/MSTP can achieve network redundancy, preventing network storm
  • Network Diagnosis and Troubleshooting can be conducted via Ping, Traceroute and Port Loopback
