Chapter 4: Cabling the Networking Ports

Cabling the Twisted Pair Ports

Here are the guidelines to cabling the 10/100/1000Base-T twisted pair ports:

The cable specifications for the 10/100/1000Base-T twisted pair ports are listed in Table 1 on page 24.

The connectors on the cables should fit snugly into the ports, and the tabs should lock the connectors into place.

The default setting for the wiring configurations of the ports is auto- MDI/MDI-X. The default setting is appropriate for switch ports that are connected to 10/100Base-TX network devices that also support auto-MDI/MDI-X.

The default auto-MDI/MDI-X setting is not appropriate for switch ports that are connected to 10/100Base-TX network devices that do not support auto-MDI/MDI-X and have a fixed wiring configuration. For switch ports connected to those types of network devices, you should disable auto-MDI/MDI-X and set the wiring configurations manually.

The appropriate MDI/MDI-X setting for a switch port connected to a 10/100Base-TX network device with a fixed wiring configuration depends on the setting of the network device and whether the switch and network device are connected with straight-through or crossover cable. If you are using straight-through twisted pair cable, the wiring configurations of a port on the switch and a port on a network device must be opposite each other, such that one port uses MDI and the other MDI-X. For example, if a network device has a fixed wiring configuration of MDI, you must disable auto-MDI/MDI-X on the corresponding switch port and manually set it to MDI-X. If you are using crossover twisted pair cable, the wiring configurations of a port on the switch and a port on a network device must be the same.

The default speed setting for the ports is Auto-Negotiation. This setting is appropriate for ports connected to network devices that also support Aut-Negotiation.

The default speed setting of Auto-Negotiation is not appropriate for ports connected to 10/100Base-TX network devices that do not support Auto-Negotiation and have fixed speeds. For those switch ports, you should disable Auto-Negotiation and set the port’s speed manually to match the speeds of the network devices.

The 10/100/1000Base-T ports must be set to Auto-Negotiation, the default setting, to operate at 1000Mbps.

The default duplex mode setting for the ports is Auto-Negotiation. This setting is appropriate for ports connected to network devices that also support Auto-Negotiation for duplex modes.

Allied Telesis has made significant strides in network infrastructure solutions with its AT-X510 series of managed Ethernet switches. The series includes models such as the AT-X510-28GTX, AT-X510-28GPX, AT-X510-52GTX, AT-X510-28GSX, and AT-X510-52GPX. These switches combine performance, flexibility, and ease of management to meet the demands of various networking environments.

One of the standout features of the AT-X510 series is its robust performance capabilities. These switches are equipped with advanced Layer 2 switching functionalities that support a range of protocols and enhance overall network efficiency. With high forwarding capacities, they ensure that data is transmitted quickly, making them ideal for bandwidth-intensive applications such as video conferencing and cloud services.

Another significant advantage of the AT-X510 series is Power over Ethernet (PoE) support, particularly in the GPX and GSX models. This feature allows the switches to deliver power to connected devices like IP cameras, Wi-Fi access points, and VoIP phones without requiring separate power supplies. This consolidates cabling, simplifies installation, and enhances flexibility in device placement.

The AT-X510 switches also incorporate advanced security functionalities like IEEE 802.1X port-based access control, which ensures that only authorized devices can connect to the network. This is particularly critical in environments where data security is a top priority. Additionally, the switches support VLANs (Virtual Local Area Networks), which help isolate network traffic, enhance performance, and provide an additional layer of security.

Management and configuration of the AT-X510 series are streamlined through an intuitive web-based interface and support for SNMP (Simple Network Management Protocol). This simplifies monitoring and troubleshooting, allowing administrators to manage the network efficiently without extensive training.

The hardware design of the AT-X510 series is also worth noting. Built with reliability in mind, these switches come with redundant power supply options, ensuring continued operation during power failures. The fanless design in some models also contributes to quieter operation, making them suitable for office environments.

Overall, the Allied Telesis AT-X510 series, including the AT-X510-28GTX, AT-X510-28GPX, AT-X510-52GTX, AT-X510-28GSX, and AT-X510-52GPX, offers a compelling combination of performance, flexibility, and security. These switches cater to the needs of modern networks, allowing businesses to build efficient, secure, and well-managed network infrastructures.
