Chapter 6: Troubleshooting

Problem 8: The AT-x510-28GPX or AT-x510-52GPX Switch is not providing power to a PoE device.

Solutions: Try the following:

Review the PD’s documentation to confirm that the device supports Mode A of the IEEE 802.3at standard. Mode A is one of two modes that define the connector pins that deliver the power from the port on the line card to the PD. In Mode A, the power is carried on pins 1, 2, 3, and 6 on the RJ-45 port, the same pins that carry the network traffic. The second mode, Mode B, defines pins 4, 5, 7, and 8 as the power carriers. The AT-x510-28GPX and AT- x510-52GPX Switches do not support Mode B. Most powered devices are designed to accept power by either mode, but some legacy devices may only support one mode. This can be verified by reviewing the device’s documentation or data sheet. Legacy devices that only support Mode B will not work with the switches.

Check that the device’s power requirements do not exceed 30 W. This can be verified by reviewing the device’s documentation or data sheet.

Verify that you are using the appropriate category of twisted-pair cable by referring to Table 3 on page 26.

Use the management software on the switch to determine whether PoE is enabled on the port. The default setting for PoE is enabled.

Use the management software on the switch to determine whether the PoE power setting for the port has been reduced to a value below the power requirements of the device.

Try connecting the device to a different port on the switch.

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.
