Fast EtherHub-12se User’s Guide

On the other hand, if two hubs are connected via 100m of fiber optic cabling, then the total length of remaining cabling that can be used to connect two end- nodes to hub 1 and 2 respectively is 367m - (2 x 80m) - (0.9 x 100) = 117m.

A more detailed example of calculating the maximum cable length for fiber optics is included in the section on 3UHFLVH￿*XLGHOLQHV￿IRU￿&RQILJXULQJ￿0XOWLSOH￿+XEV in

Chapter 3.

Providing Power to the EtherHub

1.Power on the hub by plugging the power cord into the power socket at the rear of the EtherHub (see Fig. 4-2), and the other end into a power outlet.

2.Check the LED marked Power on the front panel to see if it is on. The unit will automatically select the setting that matches the connected input voltage. Therefore, no additional adjustments are necessary when connecting it to any input voltage within the range marked on the rear panel.

Verifying Port Status

Check each connection by viewing the port status indicators listed below. (For a more detailed description of these indicators, refer to Chapter 4.)

/LQN Indicates that the port has established valid network connection.

7UDIILF Indicates traffic traversing the port.

3DUWLWLRQ Indicates that the port has been isolated from the hub due to excessive errors.

If the Link status indicator is not functioning properly, or you experience any other difficulties in setting up the hub, refer to 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.
