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

High-Density Managed Gigabit Ethernet Connectivity

The SG72860M is designed for network installations requiring a large number of Gigabit Ethernet connections along with multiple fiber-optic uplinks.

The switch provides 24 10/100/1000Mbps RJ-45 Ethernet ports and four 100/1000Mbps SFP slots, allowing copper-connected network equipment to communicate with fiber-connected network infrastructure from a single managed platform. The RJ-45 ports support auto-negotiation and auto-MDI/MDI-X, while the switch supports both multimode and single-mode fiber through compatible SFP modules.

This high-density configuration makes the SG72860M suitable for networks where multiple Ethernet devices need to be aggregated while maintaining several fiber uplink options.

192Gbps Switching Capacity

The SG72860M provides a 192Gbps switching capacity and 41.70Mpps throughput.

The switch uses store-and-forward switching and is designed for full wire-speed forwarding. It includes:

• 8K MAC table entries
• 4.1M buffer memory
• Jumbo frame support up to 10K
• 802.3x flow control for full-duplex operation
• Back-pressure flow control for half-duplex operation

These capabilities provide the switching capacity and traffic-handling resources needed for high-density Gigabit Ethernet networks.

Four SFP Fiber Uplinks

Four 100/1000Mbps SFP slots provide flexible fiber connectivity for connecting the SG72860M to network backbones, remote network segments, servers, or other fiber-connected equipment.

The switch supports both multimode and single-mode fiber using compatible LC-connector SFP modules.

VERSITRON's documented SFP options include Gigabit multimode modules and single-mode modules supporting distances ranging from short-reach connections through 100 km, depending on the selected optical module and fiber infrastructure.

Bi-directional single-mode SFP options are also documented for 10 km through 80 km connections, while CWDM and DWDM modules are available as additional options.

Fiber Connectivity from Short Reach to 100 km

The SG72860M can be configured with compatible SFP modules according to the transmission distance and fiber infrastructure required by the network.

Documented Gigabit SFP options include:

• Multimode fiber up to 550 meters
• Multimode fiber up to 2 km
• Single-mode fiber up to 10 km
• Single-mode fiber up to 20 km
• Single-mode fiber up to 40 km
• Single-mode fiber up to 70 km
• Single-mode fiber up to 100 km
• Bi-directional single-mode options from 10 km through 80 km
• CWDM and DWDM options

The appropriate SFP should be selected according to the required speed, fiber type, distance, wavelength, connector, and optical link requirements.

Although primarily a Layer 2+ managed switch, the SG72860M also provides selected Layer 3 capabilities.

The datasheet specifies:

• IPv4 management
• IPv6 management
• L3 software routing forwarding
• Static route support

These functions provide additional network-management and routing flexibility for network architectures requiring more than basic Layer 2 switching.

VLAN Support for Network Segmentation

The SG72860M supports a broad range of VLAN configurations for organizing and separating network traffic.

VLAN capabilities include:

• Port-based VLAN
• IEEE 802.1Q tag-based VLAN
• Up to 4K active VLANs
• MAC-based VLAN
• Protocol-based VLAN
• Voice VLAN
• Q-in-Q configuration
• Access, trunk, and hybrid port configurations

These functions allow network administrators to logically segment traffic and configure ports according to the requirements of different network devices and applications.

QoS and Traffic Prioritization

The SG72860M provides advanced Quality of Service capabilities for managing network traffic.

The switch supports:

• Diff-Serv QoS

These capabilities allow administrators to prioritize selected traffic and manage how network resources are allocated between different data flows.

Link Aggregation for Increased Network Resilience

The SG72860M supports both LACP and static link aggregation.

The switch can configure up to 14 aggregation groups with up to eight ports per group, providing substantial flexibility when designing aggregated network connections.

Link aggregation can be used with compatible network equipment to combine multiple physical connections into logical links for supported network architectures.

Spanning Tree and Network Redundancy

The SG72860M supports:

• STP
• RSTP
• MSTP

These spanning-tree protocols provide network loop prevention and allow administrators to design redundant network paths while maintaining controlled network topology.

Port Mirroring and Network Monitoring

The SG72860M provides port-based bidirectional data mirroring, allowing selected network traffic to be copied to another port for monitoring and troubleshooting.

The switch also provides system and port monitoring capabilities, including port status and network diagnostics.

Multicast Management

The SG72860M supports multicast traffic management through IGMP and MLD Snooping.

Features include:

• IGMP Snooping v1/v2
• Up to 1,024 multicast groups
• Fast Log Out
• MLD Snooping v1/v2
• Multicast VLAN

These functions provide administrators with greater control over multicast traffic within networks supporting applications that distribute data to multiple receiving devices.

Advanced Access Control and Network Security

The SG72860M includes extensive security and access-control capabilities extending from Layer 2 through Layer 4.

Access Control List functions include:

These capabilities provide multiple layers of access control and traffic protection for managed Ethernet networks.

High-Density Network Design

With 24 copper Ethernet ports and four SFP fiber slots, the SG72860M provides a total of 28 network interfaces in a single 1U platform.

The four SFP interfaces provide multiple options for fiber uplinks or fiber-connected network segments, while the 24 copper ports provide high-density Gigabit Ethernet connectivity for local devices.

This makes the SG72860M particularly useful when a network requires more port density than a small edge switch can provide while still needing managed fiber connectivity.

Rack-Mount Network Deployment

The SG72860M is designed for desktop or 19-inch rack-mount installation and occupies 1U of rack space.

The chassis measures approximately 17.32 × 11.42 × 1.75 inches and weighs approximately 7.05 pounds.

This form factor makes it suitable for network racks, communications rooms, equipment cabinets, and other centralized network installations.

Operating Environment

The SG72860M supports an operating temperature range of -20°C to +55°C and a storage temperature range of -40°C to +75°C.

The specified operating humidity range is 5% to 95% relative humidity, non-condensing.
