Verifying System Operation

Verify that all attached devices have a valid connection. The hub monitors link status for each port. If any device is properly connected to the hub and transmitting a link beat signal, the Link indicator lights up for the corresponding port. If the Link indicator fails to light up when you connect a device to the hub, check the following items -

Be sure the twisted-pair cable is properly attached to the connected device and the hub. Verify that the RJ-45 plug snaps into place when attached.

See if the twisted-pair cable is functioning properly by using it for another port and attached device that already displays valid indications when connected to the network.

Check the length of the twisted-pair cable to be sure it does not exceed 100 meters. Be sure the length of fiber optic cable does not exceed 112 meters. If you are using bit budget calculations to determine maximum cable lengths, then be sure you have not exceeded the maximum cable length calculated for any potential node pair.

Note: All repeater hubs provide common access to a shared medium, and therefore operate at half duplex. At half duplex, the maximum cable length that can be used for fiber optics is 112 meters. Only devices (e.g., a switch or router) which support dedicated links can operate at full duplex. When operating these device types at full duplex, the maximum cable length for fiber optics is 2 kilometers.

Verify that the workstation’s adapter card is functioning properly by trying it in another computer that has been successfully connected to the network.

If you still can’t resolve the problem, please refer to 7URXEOHVKRRWLQJ in Appendix A.

12se specifications

Accton Technology, a prominent player in the networking industry, has developed a range of high-performance switches designed to meet the demands of modern network infrastructures. Among their notable products are the EH3012C and EH3008C switches, equipped with advanced features that cater to various networking needs.

The EH3012C is a 12-port managed switch that offers a robust solution for enterprise networks. One of its standout features is its support for Layer 2/Layer 3 switching, providing flexibility for users to implement different networking protocols as needed. This switch is designed with scalability in mind, featuring high bandwidth capacities and low latency, making it suitable for high-traffic environments. Its advanced Quality of Service (QoS) capabilities allow for efficient traffic management, ensuring that critical applications receive the necessary bandwidth for optimal performance.

On the other hand, the EH3008C is an 8-port managed switch that serves as an ideal solution for small to medium-sized networks. With support for PoE (Power over Ethernet), the EH3008C significantly simplifies deployment by allowing devices such as IP cameras and access points to receive power directly through the Ethernet cable. This eliminates the need for separate power supplies and reduces clutter.

Both switches utilize advanced security features, including VLANs, port security, and Access Control Lists (ACLs), ensuring that sensitive data is protected against unauthorized access. Additionally, they support SNMP (Simple Network Management Protocol) for comprehensive monitoring and management, allowing administrators to maintain control over their network environments efficiently.

Integrating advanced technologies like SDN (Software-Defined Networking), Accton’s switches enable businesses to future-proof their network architecture. The EH3012C and EH3008C can easily adapt to evolving network demands, providing just the right mix of performance, security, and management capabilities. Furthermore, their energy-efficient designs contribute to reduced operational costs, making them a sustainable choice for organizations looking to minimize their environmental impact.

In summary, Accton Technology's EH3012C and EH3008C switches deliver powerful, feature-rich solutions tailored to both large and smaller networks. With their versatile management options, enhanced security features, and support for emerging technologies, these switches stand out as indispensable tools for building resilient and efficient networking infrastructures.
