Prioritization

simultaneously as long as the total is below its power budget. If the total exceeds the available power budget, you should consider reducing the number of PoE devices so that all of the devices receive power.

Otherwise, the switch powers a subset of the devices, based on port prioritization.

The switch can handle different power requirements on different ports. This enables you to connect different classes of PoE equipment to the ports on the switch.

If the power requirements of the powered devices exceed the switch’s power budget, the switch denies power to some ports based on a system called port prioritization. You may use this mechanism to ensure that powered devices critical to the operations of your network are given preferential treatment by the switch in the distribution of power should the demands of the devices exceed the available capacity.

There are three priority levels:

Critical

High

Low

Ports set to the Critical level, the highest priority level, are guaranteed power before any of the ports assigned to the other two priority levels. Ports assigned to the other priority levels receive power only if all the Critical ports are receiving power. Ports that are connected to your most critical powered devices should be assigned to this level. If there is not enough power to support all the ports set to the Critical priority level, power is provided to the ports based on port number, in ascending order.

The High level is the second highest level. Ports set to this level receive power only if all the ports set to the Critical level are already receiving power. If there is not enough power to support all of the ports set to the High priority level, power is provided to the ports based on port number, in ascending order.

The lowest priority level is Low. This is the default setting. Ports set to this level only receive power if all of the ports assigned to the other two levels are already receiving power. As with the other levels, if there is not enough power to support all of the ports set to the Low priority level, power is provided to the ports based on port number, in ascending order.

Power allocation is dynamic. Ports supplying power to powered devices may cease power transmission if the switch’s power budget is at maximum usage and new powered devices, connected to ports with higher priorities, become active.

You can use port prioritization on dual power supply PoE switches to protect your important networking devices from loss of power should one

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.
