24-Port Gigabit Managed Industrial Switch, with 4xGigabit Combo Port

Fiberroad FR-7M34F8 is a 24 port managed Industrial Ethernet Switch designed for industrial ethernet network applications. In such a rugged enclosure, it provides advanced IPv6/IPv4 management interfaces, comprehensive Layer 2 switching functions, and Layer 3 static routing. Industrial Ethernet switches can operate stably under temperatures from -40 degrees to 75 degrees and allow either DIN-rail or wall mounting for efficient cabinet use.

In a Harsh Environment, High Industrial Standards are Necessary

With IP40 Durable Aluminum housing and fanless design also provide efficient heat dissipation. 24 port Managed Industrial Switch provides a high level of immunity against electromagnetic interference and heavy electrical surges, usually found on plant floors or curb-side traffic control cabinets. It also possesses an integrated power supply source with a wide range of voltages (9 to 56V DC) for worldwide high availability applications requiring dual or backup power inputs. Indeed, The design of the switch ensures operates in Harsh Environment.

24 Port Industrial Ethernet Switch with Advance L2+ Features

With a 4xGigabit Combo Port (SFP/RJ45), the 24-Port Industrial Network Switch can handle extremely large amounts of data in a secure topology linking to an industrial backbone or high-capacity servers. The FR-7M34F8 is capable of providing non-blocking switch fabric and wire-speed throughput.

The Layer 2+ Managed Industrial Switch series allows the administrator to conveniently boost network efficiency by manually configuring Layer 3 IPv4/IPv6 VLAN static routing. FR-7M34F8 supports redundant ring technology and features a strong, rapid self-recovery capability to prevent interruptions and external intrusions. In addition to using advanced ITU-T G.8032 ERPS (Ethernet Ring Protection Switching), Spanning Tree Protocol, and redundant power input systems, it enhances system reliability and uptime in harsh factory environments.

Take care of the 24 Port Managed Industrial Switch Anytime and Anywhere

24 Port Managed Industrial Switch allows various network management methods, such as the Cloud(MQTT), WebGUI, CLI and NMS. The notion of easy to use, particularly with no additional hardware investment and installation. Industrial Network Switch can deploy centralised management, Layer 2 to Layer 4 QoS, Bandwidth allocation, real-time monitoring, etc.

Both SSH2.0 and HTTPS/TLS protocols are utilized to provide robust protection against network threats. It includes a range of cybersecurity features such as DHCP Snooping, IP Source Guard, ARP Inspection Protection, 802.1x port-based and MAC-based network access control, user hierarchical management, SNMPv3 authentication, and so on to complement it as an all-security solution. The 24 Port Managed Industrial Switch administrator can now construct highly-secure corporate networks with considerably less time and effort than before.
