connection to another hub or switch typically.) When used for segments going to workstation

and other user node device connections, the MDI-X push-button should be in the OUT (=)

position.

The LE1425C will support 10BASE-T unshielded twisted pair wiring (UT

environments with maximum segment distances up to 100m (325 ft.), or shielded twisted pair

wiring (STP) of 150m (500 ft.). Each port has an Activity (ACT) LED indicating packets being

received, a Link (LK) LED that indicates proper connectivity with the remote device when lit, a

FDX/HDX LED to indicate full-duplex mode when lit (or half-duplex when off), and a “speed”

LED indicating 100Mb when lit (or 10 Mbps when off).

Important Note: For the LE1425C Crossover Push-button -

OUT for workstations and user connections.

IN for Up -Link connections to other hubs, etc.

The RJ-45 pins normally (TP crossover push-button DOWN) are per the standard for hubs-to-users twisted pair wiring: 1 = receive+, 2 = receive-, 3 = transmit+, 6 = transmit -, other pins not used. When the TP crossover push-button is UP, the pins of the RJ-45 po are per the standard for up -links using twisted pair wiring, i.e., the transmit and the receive pairs are exchanged: 1 = transmit+, 2 = transmit-, 3 = receive+, 6 = receive-, other pins not used.

The LE1426C Combo 4-port

supports three auto-negotiating twisted pair

ports at 10/100Mbps FDX/HDX, and one

fiber port with 100Mbps multi-mode FX SC

connector. The three RJ-45 ports on the right

The fiber SC connector functions as a fiber optics transceiver to support 100BASE-

FX network segments. When installed in a LE14XXA-Series Fiber Switches, it supports fiber

optic cable distances up the IEEE-standard 100Mbps distance limits, i.e., typically 2km at full-

duplex and 412m at half-duplex. The factory default setting is for full-duplex operation, and a

jumper on the module must be moved to select half-duplex. (See Section 3.4).

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.
