One wire pair should be connected to pins 1 and 2 of the connector, and another wire pair should be connected to pins 3 and 6. Detailed pinout information for 10BASE-T/100BASE-TX connectors can be found in Appendix B.

Plug the RJ-45 connector at one end into the network station, and at the other end into a free 10BASE-T port (ports 3 through 18) at the front of the switch. When both the switch and the device at the other end of the connection are turned on, and the cable is connected at both ends, then the Link/Act LED should light. If it does not, then:

Be sure that the connectors are seated correctly at both ends of the cable.

Check the continuity of the wires in the cable, as well as the pin assignments on the RJ-45 connectors.

Be sure that the network station to which the port is connected is plugged in and powered on.

Be sure that you are using a Category 3 or better straight-through (not crossover) cable.

If you are connecting the switch to an Ethernet hub (or another Ethernet switch with an MDI-X port), you will need to use a crossover cable. A crossover cable can be made easily; pinout information for 10BASE- T/100BASE-TX crossover cables can be found in Appendix B.

100BASE-T Connection

The procedure for connecting 100BASE-TX Ethernet stations to the switch is the similar to that for 10BASE-T. Cabling for 100BASE-TX should be certified as Category 5 or better, and should be installed by a professional cable installer.

DES-2218 specifications

The D-Link DES-2218 is a robust and versatile 18-port Layer 2 managed switch designed for businesses seeking to enhance their network performance and reliability. With a combination of advanced features and reliable technologies, the DES-2218 offers a powerful solution for managing network traffic efficiently.

One of the standout features of the DES-2218 is its advanced Layer 2 switching capabilities. The switch supports a variety of network protocols, making it suitable for various business applications. The 18 ports, which include 16 10/100 Mbps Fast Ethernet ports and 2 Gigabit SFP slots, provide flexibility for both copper and fiber optic connections, allowing organizations to implement a tailored network infrastructure according to their specific needs.

The switch also incorporates VLAN (Virtual Local Area Network) support, enabling the segmentation of traffic for improved security and performance. This feature allows network administrators to isolate sensitive data and create efficient, manageable traffic flows that enhance overall network efficiency. Furthermore, the DES-2218 supports 802.1Q VLAN tagging, which is essential for implementing VLANs in larger, more complex networks.

In addition to VLAN capabilities, the DES-2218 offers robust Quality of Service (QoS) features. These QoS functionalities prioritize network traffic, ensuring that critical applications receive the bandwidth they need for optimal performance. This is particularly beneficial for businesses that rely on video conferencing, VoIP services, or other real-time communications.

Another notable characteristic of the D-Link DES-2218 is its support for network management protocols such as SNMP (Simple Network Management Protocol), RMON (Remote Monitoring), and WEB Management. These features enable administrators to remotely monitor and manage the network, ensuring that any potential issues can be addressed before they impact business operations.

Security is another priority in the design of the D-Link DES-2218. The switch supports various security features, including port security and MAC address filtering, which help protect the network from unauthorized access and ensure that only legitimate users can connect.

Overall, the D-Link DES-2218 is an feature-rich managed switch that combines essential technologies and characteristics to deliver a reliable networking solution for businesses of all sizes. With its extensive management capabilities, enhanced security measures, and advanced VLAN and QoS support, the DES-2218 is an ideal choice for organizations looking to optimize their network performance.
