Allied Telesis AT-FH812U-SW, AT-FH824U-SW manual Pin Assignment

AT-FH812U-SW, AT-FH812U, AT-FH824U-SW, AT-FH824U specifications

The Allied Telesis AT-FH824U and AT-FH812U series possess outstanding features suitable for various network requirements. These models are designed to deliver reliable performance, security, and ease of management for modern networking environments.

The AT-FH824U is an 8-port Fast Ethernet switch, engineered to provide high-speed connectivity for small to medium-sized networks. It supports a variety of media types and has 24 Gigabit Ethernet ports, which allow for seamless integration with existing network infrastructures. The device employs a non-blocking architecture, ensuring that data packets are routed efficiently without bottlenecks. Each port can automatically negotiate speeds between 10/100 Mbps, making it versatile for various devices. The switch also provides advanced features such as VLAN support, enabling network segmentation for improved performance and enhanced security.

Similarly, the AT-FH824U-SW variant adds an important layer to network management with its smart features. This managed switch version allows network administrators to monitor and control traffic flow through simple GUI interfaces or command-line SNMP management. The integration of Quality of Service (QoS) capabilities ensures that critical applications receive priority bandwidth, enhancing overall network efficiency.

On the other hand, the AT-FH812U is a more compact model with 12 Fast Ethernet ports. Ideal for smaller office environments, it delivers reliable networking with the same level of performance as its larger counterparts. It also supports IEEE 802.1Q for VLAN tagging, providing improved network functionality and security. This switch can be mounted in a standard rack or placed on a desktop, adding to its versatility.

The AT-FH812U-SW incorporates managed functionality, allowing users to access advanced settings and configurations. With features such as loop prevention, broadcast storm control, and port mirroring, it offers the robustness needed for more complex networking scenarios.

Allied Telesis switches are built with energy-efficient technology, minimizing power consumption without compromising performance. Enhanced security protocols including port security and access control lists make these switches suitable for businesses focused on safeguarding their networks against unauthorized access.

Overall, the AT-FH824U, AT-FH824U-SW, AT-FH812U, and AT-FH812U-SW models offer a blend of technology and performance, catering to the diverse needs of modern network infrastructures. These switches deliver scalability, manageability, and security, making them an ideal choice for various networking applications.
