28-Port Managed Industrial Switch | 24-RJ45 Ethernet Ports, 4-SFP Fiber Ports

28-Port Managed Gigabit Connectivity for Industrial Networks

The SF72860M combines high-density Gigabit Ethernet connectivity with flexible fiber-optic interfaces in a 28-port managed switch designed for industrial network environments.

The switch provides 24 dedicated 10/100/1000Mbps copper ports, two dedicated 100/1000Mbps SFP slots, and two additional combo ports. The combo ports can be used either as 100/1000Mbps SFP fiber interfaces or as 10/100/1000Mbps copper ports, allowing the network configuration to be adapted to the installation.

The RJ-45 ports support auto-negotiation and auto-MDI/MDI-X, simplifying connection to compatible Ethernet equipment.

Flexible Copper and Fiber Connectivity

The SF72860M provides multiple options for integrating copper and fiber into the same network.

The four fiber-capable interfaces consist of:

• 2 × dedicated 100/1000Mbps SFP slots
• 2 × combo ports supporting either 100/1000Mbps SFP or 10/100/1000Mbps copper

This architecture allows the switch to be configured according to the available network infrastructure and required fiber connections.

The SFP interfaces support compatible multimode and single-mode fiber modules with LC connectors.

56Gbps Non-Blocking Switching Performance

The SF72860M uses a store-and-forward switching architecture with 56Gbps non-blocking switching capacity. It provides an 8K MAC address table and supports jumbo frames up to 9.6K bytes.

The switch also supports:

• IEEE 802.3x pause-frame flow control for full-duplex operation
• Back-pressure flow control for half-duplex operation
• Auto-negotiation
• Auto-MDI/MDI-X

These functions help manage Ethernet traffic between connected copper and fiber network segments.

Layer 2 Network Management

The SF72860M provides Layer 2 management through multiple interfaces, including:

• Console
• CLI
• Telnet
• Web management
• SSH/SSL
• SNMP v1, v2c, and v3c

Port configuration includes enable/disable control, auto-negotiation, full- and half-duplex selection, and flow-control configuration.

VLAN Support for Network Segmentation

The SF72860M supports multiple VLAN functions for organizing and separating network traffic.

Supported VLAN capabilities include:

• IEEE 802.1Q tag-based VLAN
• Up to 256 VLAN groups
• Up to 4094 VLAN IDs
• Port-based VLAN
• MAC-based VLAN
• Protocol-based VLAN
• Multiple VLAN Registration (MVR)
• Q-in-Q tunneling

These capabilities provide administrators with flexibility for segmenting traffic across different network devices and applications.

Quality of Service and Traffic Control

The SF72860M provides eight QoS priority queues and supports traffic classification using IEEE 802.1p and IP DSCP.

The switch also supports ingress and egress rate control, providing administrators with additional control over network bandwidth and traffic flow.

Link Aggregation

The SF72860M supports IEEE 802.3ad LACP and static trunking, with up to five aggregation groups.

Link aggregation can be used with compatible network equipment to combine supported Ethernet connections into logical links for network architectures requiring additional bandwidth or redundancy.

Spanning Tree and Network Redundancy

The SF72860M supports:

• Spanning Tree Protocol (STP)
• Rapid Spanning Tree Protocol (RSTP)
• Multiple Spanning Tree Protocol (MSTP)

The switch also supports point-to-point and ring configurations, providing flexibility for network architectures that incorporate redundant communication paths.

These capabilities can help network administrators design networks with improved resilience and recovery from connection failures.

Port Mirroring and Network Monitoring

The SF72860M supports TX/RX many-to-one port mirroring, allowing traffic from selected ports to be copied to another port for network monitoring and troubleshooting.

The datasheet also specifies real-time monitoring, providing additional visibility into network operation.

Multicast and IGMP Management

The SF72860M supports IGMP/MLD Snooping v1, v2, and v3 with query support.

This provides managed control of multicast traffic within the Ethernet network.

Access Control

The SF72860M provides both IP-based and MAC-based Access Control Lists, with support for up to 256 entries.

These functions provide network administrators with additional tools for controlling network access and traffic.

Fiber Connectivity up to 100 km

The SF72860M supports a range of compatible VERSITRON SFP modules for different fiber types and transmission distances.

The datasheet lists Gigabit SFP options ranging from multimode connections up to 550 meters to single-mode connections extending to 100 km. It also lists bidirectional single-mode Gigabit modules for distances from 10 km through 80 km.

Available options include:

• 100Mbps multimode fiber
• 100Mbps single-mode fiber
• 1000Mbps multimode fiber
• 1000Mbps single-mode fiber
• Bi-directional single-mode Gigabit modules

The datasheet also notes that CWDM and DWDM modules are available.

The appropriate SFP should be selected according to network speed, fiber type, transmission distance, wavelength, and connector requirements.

Redundant DC Power

The SF72860M is designed with redundant DC power to support network reliability in industrial installations.

Redundant power is particularly useful in network environments where continued switch operation is important and more than one DC power source is available.

4KV Ethernet Surge Protection

The SF72860M includes 4KV Ethernet surge protection as part of its industrial design.

This protection is combined with redundant DC power, corrosion-resistant construction, and industrial-rated emission and immunity performance.

Rugged Industrial Construction

The SF72860M is designed specifically for industrial environments and incorporates:

• Corrosion-resistant construction
• Industrial-rated emission performance
• Industrial-rated immunity performance
• 4KV Ethernet surge protection
• Redundant DC power
• Extended temperature operation
• 19-inch rack mounting

The datasheet identifies these features as part of the switch's industrial design.

Extended Temperature Operation

The SF72860M is rated for operation from -40°C to +80°C. Storage temperature is also specified from -40°C to +80°C, with relative humidity from 0% to 95%, non-condensing.

This extended operating range makes the SF72860M appropriate for industrial environments subject to significant temperature variation.

19-Inch Rack-Mount Design

The SF72860M is designed for 19-inch rack mounting and measures approximately 19.01 × 11.02 × 1.77 inches.

The rack-mount design allows the switch to be integrated into centralized industrial network equipment installations.

Low Power Consumption

The SF72860M has a specified 18-watt full-load power consumption.

This relatively low power requirement is useful for installations where energy consumption and equipment heat generation are considerations.
