10/100 Fast Ethernet Switch User’s Guide

After the system’s initial check and power is on, this LED indicator is ON (green) when a secured connection is established at the port, otherwise it is OFF.

♦Console. This LED indicator is lit when the switch is being managed via out-of-band/ local console management through the RS-232 console port using a straight-through serial cable. When a secured connection is established, this LED indicator is lit green. Otherwise, it is OFF.

♦100 M. These LED indicators are illuminated (green) when a 100 Mbps device is connected to any of the 8 ports or uplink port. If a 10 Mbps device is connected to any of the 8 ports or uplink port, these LED indicators are OFF.

♦Link/Act. These LED indicators are lighted up (green) when there is a secure connection (or link) to a device at any of the ports. The LED indicators blink (green) whenever there is reception or transmission (i.e. Activity--Act) of data occurring at a port.

♦FDX/Col. This LED indicator is green when a respective port is in full duplex (FDX) mode. Otherwise, it is OFF for half duplex (HDX) operations. It blinks yellow when collisions are occurring on the respective port.

♦System Load. Indicates the current traffic load on the Switch. The system load bar provides a quick reference of the current traffic load relative to the capacity. It is a measure of the number of packets traversing within the device. Only valid packet and transmit packet are counted. The first six LED indicators are green; the last two LED indicators are yellow.

DES-3208 specifications

The D-Link DES-3208 is a robust and reliable Layer 2 Fast Ethernet unmanaged switch designed to enhance networking capabilities in both small and medium-sized businesses. With a compact and efficient design, the DES-3208 offers seamless connectivity for various devices, ensuring speedy data transfers and enhanced network performance.

One of the key features of the DES-3208 is its 8 Fast Ethernet (10/100 Mbps) ports, which allow for easy expansion of network infrastructure. The switch operates on a non-blocking architecture, which means it can handle multiple data streams simultaneously without compromising performance. This is particularly beneficial in environments where high traffic and data-intensive applications are commonplace.

The DES-3208 supports auto-MDI/MDIX functionality, which eliminates the need for crossover cables as the switch automatically detects the cable type connected. This feature simplifies network setup and allows for flexible configurations, enhancing usability for IT managers and system administrators.

Power-saving technologies are also a hallmark of the D-Link DES-3208. It features innovative Green Ethernet technology that reduces power consumption by detecting inactive ports and adjusting power usage accordingly. This not only contributes to environmental initiatives but also provides cost savings on energy bills over time.

Additionally, the switch supports a variety of network protocols to ensure compatibility with different network environments. These features include IEEE 802.3x flow control, which helps prevent packet loss during data transmissions, and IEEE 802.1p prioritization, ensuring critical traffic is processed in a timely manner.

The fanless design of the DES-3208 contributes to silent operation, making it an ideal choice for office environments where minimal noise is preferred. The compact form factor further allows for easy placement either on a desk or in a rack mount.

Overall, the D-Link DES-3208 is a versatile and efficient solution for businesses seeking an unmanaged switch that balances performance, energy efficiency, and ease of use. It adeptly meets the needs of growing networks while providing essential features that promote reliability and connectivity.
