LE1423C is a 4-port multi-mode fiber FX “small-form-factor” VF-45 connector used imarily in 100Mbps fiber-to-the-desktop links. Its size is similar to the MT-RJ port, but the

F-45 shell is slightly larger. When not in use, its appearance is distinctive because it has a tiny nged door over the port hole to act as a dust cover.

When installed in a LE14XXA-Series

The cable port is a “plug-in” connector, with

The module is uipped with a LINK (LK) LED to indicate proper connectivity with the remote device, an CTIVITY (ACT) LED that flashes to show when Fast Ethernet packets are being received and (FDX/HDX) LED indicate the full-duplex mode when lit (or half-duplex when off).

The LE1425C module supports Ethernet twisted pair segments of any standard length. is equipped with 4-port RJ-45 connector with 10/100 and auto-negotiating capability on each ort. The RJ-45 connector is shielded to minimize emissions and will allow both unshielded isted pair (UTP) and shielded twisted pair (STP) cable connections.

The LE1425C 4-port module is equipped with a Media Dependent Interface- rossover (MDI-X) push-button to allow for one cascaded connections. This feature eliminates e need for a special twisted pair crossover

ble when connecting to a hub or another witch.

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.
