AT-FS238 Series specifications

The Allied Telesis AT-FS238 Series is a robust line of Ethernet switches designed to cater to the networking demands of small to medium-sized businesses. These switches are engineered to provide a reliable, cost-effective solution for organizations seeking to enhance their network infrastructure. With a focus on performance and user-friendliness, the AT-FS238 Series stands out in the competitive landscape of networking equipment.

One of the key features of the AT-FS238 switches is their impressive port density. The series comprises models that offer multiple 10/100BASE-TX ports, allowing for a seamless connection of various devices such as computers, printers, and IP phones. The switches are equipped with auto-sensing capabilities, meaning they automatically identify the speed of connected devices and adjust accordingly. This feature ensures optimal data transfer rates while supporting both legacy and modern devices.

Another significant characteristic of the AT-FS238 Series is its support for Quality of Service (QoS). This technology allows the switch to prioritize traffic, ensuring that time-sensitive applications such as voice and video maintain high performance levels. By managing bandwidth effectively, the AT-FS238 helps reduce latency and jitter, providing a smoother experience for critical applications.

The AT-FS238 switches also incorporate VLAN (Virtual Local Area Network) capabilities. This functionality allows network administrators to segment the network into smaller, manageable parts, enhancing security and improving network performance. By isolating traffic, VLANs can help to prevent broadcast storms and limit the spread of network issues, thereby maintaining optimal functioning.

Energy efficiency is another standout aspect of the AT-FS238 Series. These switches conform to Energy Star standards, allowing organizations to reduce power consumption without sacrificing performance. The implementation of power-saving technologies helps organizations cut down on energy costs while contributing to environmentally friendly practices.

Additionally, the AT-FS238 Series is designed for ease of management. With a user-friendly interface and features like auto-negotiation and link aggregation support, network configuration and monitoring become streamlined processes. This simplicity empowers even non-technical staff to manage network settings effectively.

In summary, the Allied Telesis AT-FS238 Series offers a blend of essential features such as high port density, QoS support, VLAN capabilities, energy efficiency, and intuitive management tools. These characteristics make the AT-FS238 Series an excellent choice for businesses looking to enhance their network infrastructure and ensure reliable, high-performance connectivity.
