10/100 Fast Ethernet Switch User’s Guide

Using a Straight Cable

When using straight cable, the connection can be made from the uplink (MDI-II) port of the Switch to any port of the Hub (see figure 7).

Using a Crossover Cable

When using crossover cable, the connection can be made from any port of the Switch to any port of the Hub (see figure 7).

Configuring the Port Speed & Duplex Mode

After plugging the selected cable to a specific port, you can configure the communication mode through console program (Auto Negotiation Enable/disable, Port Speed) and Dip switch (Half/Full Duplex) on the rear panel of the Switch:

1.If you have auto-negotiation disabled, an auto-sensing process is initiated to select the speed, and the duplex mode will be set based on the Dip switch setting.

2.If you have auto-negotiation enabled, but the partner does not support auto-negotiation. Then an auto-sensing process is initiated to select the speed, and the duplex mode is set based on the Dip switch setting.

3.If auto-negotiation is supported and enabled on both ends of the connection and Dip switch is set to half-duplex (HDX), Dip switch down, the auto-negotiation process is initiated to negotiate for one of the following modes:

100Mbps/HDX

10Mbps/HDX

4.If auto-negotiation is supported and enabled on both ends of the connection and Dip switch is set to full-duplex (FDX), Dip switch up,

DES-1012 specifications

The D-Link DES-1012 is a robust solution that delivers reliable and efficient networking capabilities, making it ideal for small to mid-sized business environments. This 10/100 Mbps Ethernet switch is designed to provide high-performance data transfer, ensuring smooth communication within networks.

One of the primary features of the D-Link DES-1012 is its 12 10/100 Mbps Auto-Negotiation ports. These ports automatically detect the network speed of connected devices, allowing for easy and efficient integration into existing network infrastructures. The switch's plug-and-play design eliminates the need for extensive configuration or setup, making it accessible for users with varying levels of technical expertise.

The DES-1012 supports various network technologies, enhancing its versatility in different environments. It uses (Store-and-Forward) switching, which ensures the integrity of data being transmitted by checking for errors before forwarding packets. This feature is essential in minimizing data loss and ensuring reliable communication between devices. Additionally, the switch offers full-duplex communication, allowing data to be sent and received simultaneously, effectively doubling the bandwidth and improving overall network performance.

Energy efficiency is another key characteristic of the D-Link DES-1012. The switch is designed to reduce power consumption without compromising performance, making it an environmentally friendly choice for businesses looking to lower their energy costs. It achieves this through features like IEEE 802.3az Energy Efficient Ethernet, which intelligently manages power usage based on the amount of network traffic.

Furthermore, the D-Link DES-1012 incorporates QoS (Quality of Service) functionality, prioritizing critical applications and ensuring that bandwidth for voice, video, and data traffic is managed effectively. This feature is particularly beneficial in scenarios where real-time communication is vital, such as VoIP calls and video conferencing.

In conclusion, the D-Link DES-1012 is a well-rounded Ethernet switch that combines efficiency, performance, and ease of use. Its 12 ports, support for essential networking technologies, commitment to energy efficiency, and QoS functionality ensure that it meets the demands of modern business networks. Whether for expanding existing networking capabilities or establishing new ones, the DES-1012 proves to be a reliable choice.
