10/100 Fast Ethernet Switch User’s Guide

Using a Crossover Cable

When using crossover cable, this is done from any (MDI-X) port of the Switch (Switch A) to any of the 10Mbps or 100Mbps (MDI-X) port of the other switch (switch B) or other devices (see figure 8).

Switch A’s LED indicators for the respective connected ports are as follows:

♦100 M is ON for 100Base-TX, otherwise it is OFF.

♦Link/Act is ON.

♦FDX/Cool depends on the connected switch or other device.

Console Management Program

This section discusses how to manage the DES-1012 using the console management program. It describes the steps required to set up a console device and details how to configure the console program.

Overview

The console program allows you to manage the DES-1012 and monitor its performance. You have to access this program through a direct connection between a management console and the console port of the DES-1012. The management console used for the connection can be a VT-100 terminal or a PC running terminal emulation software.

Setting Up a Console Device

To set up the connection, follow these steps:

1.Connect a terminal or a PC with terminal emulation software to the console port using the RS-232 cable.

2.The console port on the management module is a DTE DB-9 connector. You need a null adapter installed between the cable and the console port.

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.
