3-Slot Managed Modular Network Switch

Flexible Modular Network Connectivity

The SG71090A is designed for networks where a fixed-port switch may not provide the right combination of copper and fiber connectivity.

Instead of being limited to a predetermined port configuration, the SG71090A uses three modular slots that accept interchangeable 8-port modules. This allows network designers to configure the switch around their specific connectivity requirements.

A fully populated chassis can provide up to 24 network ports, depending on the modules selected.

The available modules include Gigabit copper, 100Base multimode and single-mode fiber, 100/1000Base SFP, and mixed copper/fiber configurations.

Configure the Switch Around Your Network

The SG71090A provides several ways to combine copper and fiber connectivity within the same chassis.

Available Module Configurations

The chassis model is SG71090A.

High-Bandwidth Switching Performance

The SG71090A provides 48Gbps switching capacity and 71.4Mpps throughput, supporting high-volume network traffic across copper and fiber interfaces. It uses store-and-forward switching and includes a 12MB packet buffer and 16K MAC address table.

The switch also supports jumbo frames up to 10K, providing additional flexibility for networks handling large data transfers.

Advanced Network Management

The SG71090A is a fully managed platform with multiple management interfaces and network-management functions.

Management options include:

• Web management through HTTP/HTTPS
• SNMP V1/V2C/V3
• Console
• Telnet
• SSH 2.0 CLI
• TFTP
• FTP
• Syslog
• RMON
• NTP
• LLDP
• Temperature monitoring
• Ping and Traceroute
• SFP Digital Diagnostic Monitoring (DDM)

These capabilities allow network administrators to monitor, configure, troubleshoot, and manage the switch across a range of network environments.

VLAN, QoS, and Traffic Management

The SG71090A provides extensive traffic-management capabilities for networks requiring segmentation and prioritization.

Supported VLAN functions include:

• MAC-based VLAN
• IP-based VLAN
• Protocol-based VLAN
• Q-in-Q configuration
• Access, trunk, and hybrid port configurations

QoS capabilities include class-based QoS, remarking, ingress and egress port rate limiting, policy-based QoS, and SP/WRR queue scheduling.

The switch also supports port mirroring, traffic statistics, network storm suppression, and port isolation.

Network Redundancy and Ring Protection

For applications where network availability is critical, the SG71090A supports multiple spanning-tree and ring-network protocols.

Supported protocols include:

• STP
• RSTP
• MSTP
• G.8032 ERPS
• Single-ring configurations
• Sub-ring configurations
• Other ring configurations

The switch also supports static and dynamic port aggregation at 1G/2.5G.

These features allow the SG71090A to be incorporated into network architectures designed for redundancy and rapid recovery.

Advanced Network Security

The SG71090A includes multiple security features for controlling network access and protecting network traffic.

Security capabilities include:

• IEEE 802.1X authentication
• MAC address authentication
• RADIUS service
• Port security
• IP source protection
• IP-MAC-Port binding
• ARP inspection
• ARP packet filtering
• Port isolation

The switch also supports standard, extended IP, and extended MAC access control lists (ACLs).

Flexible Fiber Connectivity

The SG71090A can be configured with either 100Base on-board fiber optics or 100/1000Base SFP modules, depending on the module installed.

The SFP architecture provides additional flexibility because the appropriate transceiver can be selected according to the fiber type and required transmission distance.

The datasheet lists VERSITRON SFP options supporting multimode and single-mode fiber applications from short-distance links through 100 km Gigabit configurations, along with single-fiber bidirectional options. CWDM and DWDM modules are also available.

Available SFP Options

The SG71090A supports a broad range of VERSITRON SFP modules.

Gigabit options include:

• Multimode up to 550 meters
• Multimode up to 2 km
• Single-mode up to 10 km
• Single-mode up to 20 km
• Single-mode up to 40 km
• Single-mode up to 70 km
• Single-mode up to 100 km
• Single-fiber BiDi configurations from 10 km to 80 km

The datasheet also lists 100Mbps multimode and single-mode SFP options.

Installation and Power Options

The SG71090A is designed for flexible installation and can be deployed as a:

• 19-inch rack-mounted 1U switch
• Desktop switch
• Shelf-mounted switch

The standard power input is 100–240VAC, 50/60Hz, with an optional 36–75VDC power configuration. Power consumption is specified at 30W or less.

The operating temperature range is -10°C to +50°C, with working humidity of 10–90% and storage humidity of 5–95%.

Typical Applications

The modular architecture makes the SG71090A particularly useful for networks where copper and fiber requirements may vary between installations.

Typical applications include:

• Enterprise networks
• Industrial Ethernet networks
• Fiber backbone networks
• Security and surveillance networks
• Transportation networks
• Telecommunications
• Government networks
• Data aggregation
• Campus networks
• Network infrastructure requiring mixed copper and fiber connectivity

Why Choose the VERSITRON SG71090A?

The SG71090A is designed for organizations that need more flexibility than a conventional fixed-port Ethernet switch can provide.

Its three-slot architecture allows network designers to select the combination of copper, fiber, and SFP interfaces that best matches the installation rather than purchasing a switch with a fixed port configuration.

With 48Gbps switching capacity, advanced Layer 2+ management, VLAN and QoS functions, extensive security controls, ring-network redundancy, and support for multiple fiber configurations, the SG71090A provides a scalable platform for evolving network requirements.

VERSITRON Fiber Optic Networking Since 1958

Since 1958, VERSITRON has provided fiber optic and Ethernet communication solutions for demanding network environments.

The SG71090A continues that tradition with a configurable modular switching platform designed to integrate copper Ethernet and fiber optic connectivity into a single managed network solution.
