Assignments

1.Verify that the cabling type is correct. Be sure all cable connectors are securely seated in the required ports. Use 100 Ohm Category 5 straight-through cable for all standard twisted-pair connections.

2.Make sure all devices are connected to the network. Equipment may have been unintentionally disconnected from the network.

3.This is a Class II hub and can only be cascaded from a repeater port to one other hub using 5 meters (16 feet) of cabling if the link is operating at 100 Mbps. If you must connect to more than one hub, use an optional Media Expansion Module or a switch.

4.If you want to connect to another hub or a switch, use an RJ-45 MDI to MDI-X connection. If you must cascade to a hub or switch using MDI-X ports at both ends of the cable (not the MDI port), make sure a crossover cable is used (see “Making a Connection via an MDI-X Station Port” on page 5). Crossover cable should only be used if an MDI daisy-chain port is not available.

Make sure the network interface hardware and software drivers for the attached devices are functioning properly. Check the adapter cards and associated drivers used in any attached workstation or server.

RJ-45 (MDI-X) station ports (see Figure 11) can be attached to any devices which use a standard network interface (for example, a workstation, server, bridge or router). The RJ-45 (MDI) daisy-chain ports can be cascaded to a station port on similar networking devices (for example, another hub or switch). Use UTP or STP cable for RJ-45 connections: 100 Ohm Category 3, 4 or 5 cable for 10 Mbps connections or 100 Ohm Category 5 cable for 100 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet), and that the length of any cascaded connection from a repeater port to another hub does not exceed 5 meters (16 feet) if the link is operating at 100 Mbps.

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.
