Managed 24-Port Gigabit Ethernet + 4-Port Gigabit SFP/Ethernet Industrial Switch

View : 482
Type : Managed Rackmount Industrial Switch
Description :

The industrial-grade 24+4 switch is a new generation of multi-service access ethernet switch with high integration, rich functions, and simplicity.


The industrial-grade 24+4 switch is a new generation of multi-service access ethernet switch with high integration, rich functions, and simplicity. It contains 24 gigabit ethernet ports and 4 gigabit optical-ethernet multiplexing ports, making it particularly suitable for applications with large data streams, such as video transmission. It supports a variety of layer 2 management protocols required for industrial switching applications and ITU G.8032 redundant ring network protocol, with a self-healing time of less than 20ms, ensuring the real-time and stable operation of the network.


The switch adopts mature technology and open network standards, and is designed to meet the rigorous working environment requirements of industrial sites, including low and high temperatures, strong electromagnetic interference, salt spray resistance, and shock resistance. It provides an efficient, reliable, and fast solution for the industrial Internet of Things.


The switch comes with a 19-inch full aluminum alloy case with heat dissipation strips, good heat dissipation performance, gold oxide process, IP40 protection level, and it is designed for harsh industrial environments.

It supports 24 gigabit ethernet ports and 4 gigabit optical/ethernet COMBO ports.

Each ethernet or optical port supports standard ERPS ring network protocol, with a self-healing time of less than 20ms.

It supports port-based bandwidth limitation, port-based traffic control, and broadcast storm control.

It supports Web, CLI, and Telnet management.

It provides power failure alarm, loop alarm, and Console debugging.

It supports POE (POE+) devices.

Management functions:

  Support CLI, WEB, SNMP management methods.

  Support port-based ingress/egress rate limiting, half-duplex backpressure flow control, and 802.3X full-duplex flow control.

  Support broadcast, multicast, and unknown unicast storm control.

  Support IEEE 802.1Q 4K VLAN and QINQ.

  Support port mirroring, Syslog, Ping command, etc.

  Support COS, DSCP, 8 queues, and WRR, SP, WFQ scheduling modes, and policy QoS.

  Support port traffic statistics and online upgrades.

  Support STP/RSTP, MSTP, EAPS, and ERPS.

  Support IGMP Snooping V1/V2/V3 and GMRP.

  Support manual aggregation, and static/dynamic LACP protocols.

  Support relay alarm, RMON management, and TRAP alarm.

  Support DHCP Snooping, Option 82, and 802.1X.

  Support user-level management and ACL access control lists.

  Support DDOS, and port-based MAC filtering/binding.

The Ethernet interface comes with three-level lightning protection, which can withstand short-circuit current waves of 10/700μs and open circuit peak output voltages of 6KV according to GB/T17626.5(IEC61000-4-5) standards.

Multiple power supply options, including AC220V, DC-48V/DC+24V/ DC+12V, etc. It also supports dual power backup, such as AC+DC, AC+AC, DC+DC, etc.
