3-Slot Managed Modular Network Switch

The SG71090A Pick-a-Port Modular Ethernet Switch consists of a three-slot chassis that accepts interchangeable 8-port modules.

A fully populated chassis supports up to 24 network ports, with module options for copper Ethernet, multimode fiber, singlemode fiber, and SFP-based fiber connectivity.

The modular design allows you to select the exact combination of interfaces required for your network rather than purchasing a fixed-port switch that may contain ports you do not need.

Configure Your Network With Interchangeable Modules

The Pick-a-Port architecture provides multiple module configurations for building a customized Ethernet and fiber optic network.

Available modules support:

• 10/100/1000 Mbps RJ45 copper Ethernet
• 100Base-FX multimode fiber
• 100Base-FX singlemode fiber
• 100/1000 Mbps SFP fiber
• Mixed copper and fiber configurations
• Fixed ST and SC fiber interfaces
• LC fiber connectivity through SFP modules

SFP modules are available for different wavelengths, transmission distances, and duplex or simplex fiber applications.

This allows the SG71090A to support networks containing different fiber types, transmission distances, and interface requirements within the same chassis.

Modular Ethernet Switch Module Options

Build Copper, Fiber, or Hybrid Network Configurations

One of the primary advantages of the Pick-a-Port architecture is the ability to mix different interface types within one chassis.

For example, a network can be configured with:

• Copper Ethernet ports for local computers and equipment
• Multimode fiber ports for shorter-distance fiber links
• Singlemode fiber ports for longer-distance connections
• SFP ports for flexible optical transceiver selection
• A combination of copper and fiber interfaces

For applications requiring an all-fiber network, the SG71090A can also be configured with 8-, 16-, or 24-port all-fiber configurations.

This makes the modular platform particularly useful when different areas of a network have different connectivity requirements.

Managed Network Control and Performance

The SG71090A combines modular hardware flexibility with managed network functionality.

Management features allow network administrators to configure, monitor, and optimize network operation.

Depending on the configuration and application, the switch supports features including:

• VLAN
• 802.1Q VLAN tagging
• 802.1p Quality of Service
• 802.1x port-based authentication
• Spanning Tree Protocol
• IGMP Snooping
• Port trunking and load sharing
• Port mirroring
• RMON
• MAC address control
• Rate control
• Broadcast and packet storm control
• Flow control
• Static and dynamic MAC address limitations

The switch also supports Web-based management, SNMP, Telnet, and Console interfaces, providing multiple ways to configure and monitor the network.

Flexible Fiber Connectivity With SFP

SFP compatibility gives the Pick-a-Port platform additional flexibility when designing fiber optic links.

Instead of being restricted to a single permanently installed optical configuration, SFP-based modules can accommodate different optical requirements by selecting an appropriate SFP transceiver.

This can be useful when network links have different:

• Transmission distances
• Fiber types
• Wavelength requirements
• Duplex or simplex configurations
• Data-rate requirements

Applications for Modular Ethernet Switches

The flexibility of the Pick-a-Port architecture makes it suitable for networks where copper and fiber connectivity requirements vary.

Modular Ethernet switches can provide connectivity between equipment throughout substations while allowing copper and fiber interfaces to be combined within the same chassis.

Fiber connectivity can also provide electrical isolation and immunity to electromagnetic interference in demanding environments.

Utility networks often connect equipment located across different areas and distances. A modular switch can accommodate different copper and fiber connections while supporting centralized network management.

Industrial facilities and remote equipment may require a combination of copper and fiber networking. The modular architecture allows network designers to configure connectivity around the specific equipment and transmission distances involved.

Rail networks can require reliable communication between control, signaling, monitoring, and other networked systems. A configurable combination of copper and fiber ports can simplify network design.

Manufacturing environments can contain a variety of networked equipment with different interface requirements. The modular switch provides a configurable platform for connecting production and monitoring equipment.

The Pick-a-Port platform can also be used where a network needs a combination of Ethernet and fiber connectivity without deploying separate switches for each interface type.

Benefits of the Pick-a-Port Modular Design

The modular architecture allows the switch to accommodate changing network requirements. Rather than replacing an entire switch when connectivity requirements change, the appropriate module can be selected for the application.

The same chassis can accommodate copper Ethernet, multimode fiber, singlemode fiber, and SFP-based fiber connectivity.

Combining different interface types within one chassis can reduce the need to deploy separate switches for different portions of the network.

The modular design provides a practical foundation for expanding or modifying a network as additional equipment or fiber links are introduced.

Because the SG71090A is a managed modular switch, administrators can use its management capabilities to monitor and configure network operation.

For networks that require fiber connectivity throughout, the chassis can be configured with 8, 16, or 24 fiber ports.

A Modular Switch That Adapts to Your Network

The VERSITRON Pick-a-Port Modular Ethernet Switch is designed for organizations that need more flexibility than a fixed-configuration Ethernet switch can provide.

By combining interchangeable copper and fiber modules within one managed chassis, the SG71090A allows network designers to create a configuration around the actual requirements of the application.

Whether you need a mixed copper/fiber network, an all-fiber configuration, different fiber transmission distances, or the flexibility to modify the network in the future, the Pick-a-Port architecture provides a versatile platform for building and expanding your network.
