3. Basic Concept and

Management

This chapter will tell you the basic concept of features to manage this switch and how they work.

3-1. What’s the Ethernet

Ethernet originated and was implemented at Xerox in Palo Alto, CA in 1973 and was successfully commercialized by Digital Equipment Corporation (DEC), Intel and Xerox (DIX) in 1980. In 1992, Grand Junction Networks unveiled a new high speed Ethernet with the same characteristic of the original Ethernet but operated at 100Mbps, called Fast Ethernet now. This means Fast Ethernet inherits the same frame format, CSMA/CD, software interface. In 1998, Gigabit Ethernet was rolled out and provided 1000Mbps. Now 10G/s Ethernet is under approving. Although these Ethernet have different speed, they still use the same basic functions. So they are compatible in software and can connect each other almost without limitation. The transmission media may be the only problem.

In Fig. 3-1, we can see that Ethernet locates at the Data Link layer and Physical layer and comprises three portions, including logical link control (LLC), media access control (MAC), and physical layer. The first two comprises Data link layer, which performs splitting data into frame for transmitting, receiving acknowledge frame, error checking and re-transmitting when not received correctly as well as provides an error-free channel upward to network layer.

ES-516G+ specifications

Edimax Technology has carved a niche for itself in the realm of networking devices, and one of its standout products is the Edimax ES-516G+. This 16-port Ethernet switch is designed to meet the demanding needs of small to medium-sized businesses and network enthusiasts.

At the core of the ES-516G+ is its capacity to support 10/100/1000 Mbps speeds across its 16 ports, enabling efficient data transmission and minimal latency for connected devices. This switch is a Layer 2 unmanaged switch, which simplifies the user experience by eliminating the need for complex configurations. Users can plug in their devices and start functioning immediately, making it an ideal option for those who may not have extensive networking knowledge.

One of the key features of the Edimax ES-516G+ is its support for Auto-MDI/MDI-X, which automatically detects the type of connection required for each port, whether it’s connecting to another switch or end devices like computers and printers. This eliminates the hassle of crossover cables and ensures seamless connectivity.

Moreover, the ES-516G+ incorporates advanced energy-saving technologies that are designed to minimize power consumption without compromising performance. This feature is particularly appealing for environmentally-conscious businesses looking to reduce their carbon footprint. It includes capabilities such as energy-efficient Ethernet (EEE), which adjusts power usage based on the link status and length of connected cables.

The switch features a compact metal housing, providing durability and a professional look suitable for any office environment. It also supports a fanless design for quiet operation, making it an excellent addition to workplaces where noise levels need to be kept to a minimum.

In terms of performance, the Edimax ES-516G+ employs store-and-forward switching technology, which helps to minimize errors by ensuring that only error-free packets are forwarded. This significantly enhances network performance and reliability.

Overall, the Edimax Technology ES-516G+ stands out as a robust, efficient, and user-friendly solution for enhancing network performance in small to medium-sized businesses. Its combination of speed, plug-and-play convenience, energy-saving features, and reliability makes it a compelling choice for users seeking to expand their network capabilities. Whether for a bustling office or a home network, the ES-516G+ is engineered to deliver a seamless, high-performance networking experience.
