Chapter 2: Overview

2. Overview

2.1 Introduction

The 10/100/1000 RJ-45 Unmanaged Switches provide 16 or 24 10/100/1000 Mbps ports. They’re easy to install and provide high performance in an environment where trafffic on the network and the number of users increases continuously. The switches support the highest speed even when operating in full-duplex mode.

The switches also provide automatic crossover detection on each port. It’s simple and friendly to uplink to another switch without a crossover cable.

Use the switches for medium to large workgroups. It’s easy to upgrade network capacity, and you can mount the switches in a 19" rack or cabinet.

2.2 Features

Complies with IEEE 802.3 Ethernet, IEEE 802.3u Fast Ethernet, and IEEE 802.3ab

Gigabit Ethernet standards.

Has 16 or 24 autonegotiating 10/100/1000 ports.

Fits in a 19" rack or cabinet.

Enables non-blocking and non-head-of-line blocking full wire-speed forwarding.

Supports store-and-forward operation.

Provides 8K MAC address entry.

Supports broadcast storm filtering.

All ports provide Auto-MDI/MDI-X crossover.

Uses backpressure flow control for half-duplex operation, and IEEE 802.3x for full-duplex mode.

Smart plug-and-play.

Black Box 16-/24-Port 10/100/1000 RJ-45 Unmanaged Gigabit Switches Overview Introduction, Features, What’s Included

16-/24-Port 10/100/1000 RJ-45 Unmanaged Gigabit Switches, LGB424A, LGB416A specifications

Black Box 16-/24-Port 10/100/1000 RJ-45 Unmanaged Gigabit Switches, specifically the LGB424A and LGB416A models, are essential networking devices designed to enhance the performance and reliability of your local area network (LAN). Their robust construction and efficient functionality make them a popular choice among small to medium-sized businesses and home office users who seek seamless data transmission and connectivity.

One of the distinguishing features of these unmanaged switches is their plug-and-play capability. With no configuration or management required, users can simply connect their devices, and the switch will automatically detect the network and initiate communication. This simplicity is particularly beneficial for those who may not have extensive networking knowledge or for environments where quick setup is desirable.

The LGB424A model offers 24 RJ-45 ports, while the LGB416A features 16 ports. Both models support Auto-Negotiation technology, allowing the switches to automatically adjust the speed and duplex settings to optimize performance for connected devices. This capability ensures that the switches can handle various network speeds, including 10/100/1000 Mbps, enabling seamless integration with older equipment as well as modern high-speed devices.

Power over Ethernet (PoE) support in some configurations allows for the delivery of power and data through a single cable, simplifying installations and reducing clutter. This feature is particularly advantageous for applications involving IP cameras, wireless access points, and VoIP phones.

Both switches are designed with a durable metal chassis, ensuring their longevity and reliability in demanding environments. Their fanless design contributes to silent operation, making them suitable for placement in noise-sensitive areas. Moreover, the auto-MDI/MDI-X feature provides flexibility in cable connections, eliminating the need for crossover cables when connecting similar devices.

The LGB424A and LGB416A also prioritize efficient power consumption, conforming to energy-saving standards while maintaining high performance. These unmanaged switches represent an optimal solution for users seeking reliable, cost-effective networking solutions without the need for advanced management features. Whether for a small office or an expanding network, Black Box Gigabit Switches deliver dependable performance and connectivity.
