Black Box Modular Switches

Installation and User Guide (8/99)

Example 3 : 16-port LE1416A

In another situation similar to Example 2 above, a larger central Switch is needed to provide for a 6-segment 100Mb fiber Fast Ethernet backbone, and switched copper support for 4 high speed local servers. In addition, the router and two dual-speed hubs need switched coppe ports. The total is 14 ports, 6 fiber and 8 copper.

The mixed-media flexibility of the Black-Box 4-Port Switches provides the user with more than one configuration in this case. The two ports not immediately used may be either fib or copper. If the probable growth of the central Switch is towards more fiber backbone segments, then two 4-port fiber 4PMs are selected to provide 6 required fiber ports and two fo spares and/or future backbone expansion. The 8 switched copper ports are handled with two R 45 4-Port Modules configured into the LE1416A. Should the number of servers expand, more than one server can be serviced by a switched LE1416A port by using a small 4-port 100Mbps hub.

If the probable growth of the central Switch is towards more local high speed servers and users, then one 4-port fiber 4PM is selected to provide 4 of the required fiber ports, and tw “combo 3 RJ-45 + 1 fiber” 4PMs are configured for the other 2 fiber ports plus 6 of the switch copper ports. Finally, an RJ-45 QPM is configured to provide for the remaining 2 copper ports plus two for spares and/or future expansion. Should the need arise to add a built -in-fiber backbone port in the future, the RJ-45 4PM could be removed and another “3+1 combo” 4PM installed in the field. Alternatively, a 100MB Media Converter (such as the LH1500A-ST-R2) may be used on a copper port, with internal jumpers (See Section 3.4) set to support fixed 100MB FDX on the RJ-45 port.

LE14XXA, Modular Switches specifications

The Black Box LE14XXA series of modular switches are designed for high-performance networking in both small and medium enterprises, as well as in larger data center environments. These switches stand out due to their scalability, flexibility, and robust functionality, making them suitable for a variety of applications.

One of the main features of the LE14XXA modular switches is their modular design, allowing for the integration of various interface cards to tailor the switch to specific networking needs. This flexibility ensures that organizations can adapt their network architecture as requirements evolve, making it a future-proof investment. The switches support a range of modules, including Ethernet, fiber optics, and PoE (Power over Ethernet), which can be easily swapped out or added to support changing technology demands.

In terms of performance, the LE14XXA series offers impressive throughput capabilities, often supporting up to 10 Gbps per port. This speed is critical for businesses that rely on fast data transfer rates for tasks such as video conferencing, large file transfers, and real-time applications. The switches also feature advanced Layer 2 and Layer 3 functionalities, facilitating efficient data routing and switching, which is essential for maintaining effective network performance.

Security is another critical characteristic of the Black Box LE14XXA switches. They incorporate a variety of security protocols, including 802.1X port-based access control, VLAN support, and secure management interfaces, which help protect sensitive data and ensure compliance with industry standards. This makes them an excellent choice for organizations that prioritize data protection and regulatory compliance.

Ethernet redundancy protocols, such as Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP), enhance network reliability by providing failover options in case of link failures. Additionally, the LE14XXA switches feature energy-efficient designs that comply with energy-saving standards, which can significantly reduce operational costs over time.

User-friendly management interfaces, including a web-based GUI and command-line interface (CLI), simplify the configuration and monitoring processes. This ensures that IT administrators can efficiently handle the network without extensive training or experience.

Overall, the Black Box LE14XXA modular switches combine advanced technology, security features, and versatile design, making them a powerful choice for modern networking needs. Their adaptability and high performance offer businesses the capability to build scalable and secure networks that can grow alongside their operations.
