Chapter 1: Overview

Power Over Ethernet Plus (PoE+)

The following section applies to x610-24Ts-POE+, x610-24Ts/X-POE+, x610-48Ts-POE+ and x610-48Ts/X-POE+ Gigabit Ethernet switches only.

The 10/100/1000Base-T ports on these switches feature Power over Ethernet (PoE), defined in the IEEE 802.3af standard, and Power over Ethernet Plus (PoE+), defined in the IEEE 802.3at standard.

PoE+ is a mechanism for supplying power to network devices over the same twisted pair cables used to carry network traffic. Power is injected on the Ethernet cabling along with data by Power Sourcing Equipment (PSE), like an Ethernet LAN switch or router. A device that receives its power over an Ethernet cable is called a Powered Device (PD).

The switch automatically determines whether or not a device connected to a port is a PD. A PD has a signature resistor or capacitor that the switch can detect over the Ethernet cabling. If the resistor or capacitor is present, the switch assumes that the device is a PD.

Once a PD is discovered, a PSE may optionally perform PD classification by applying a DC voltage to the port. If the PD supports optional power classification it will apply a load to the line to indicate to the PSE the classification the device requires.

For more detailed information about PoE+ see the latest release of the AlliedWare Plus Operating System Software Reference Guide.

Power Classes Since PDs may require differing power ranges, the IEEE 802.3at Power Ethernet standards classifies PDs according to their power consumption. By providing the PSE with its power range, the PD allows the PSE to supply power with greater efficiency. The power classes as outlined by IEEE 802.3at are as follows, showing the different PD classes and the PSE power output for each corresponding PD power range:

Allied Telesis has made a significant mark in the networking hardware industry with its impressive lineup of switching solutions. Among these, the X610 series stands out, offering a range of models including the X610-48TS, X610-24TS/X-POE+, X610-24TS/X, X610-48TS-POE+, and X610-24TS-POE+. These switches are designed for robust performance, scalability, and energy efficiency, catering to the needs of businesses and organizations of various sizes.

The X610-48TS model features 48 Gigabit Ethernet ports, providing high-density connectivity options that are essential for modern network architectures. Complementing this, the X610-24TS models, which come with 24 ports, are ideal for smaller deployments while still delivering significant capacity and performance. The X610-24TS/X-POE+ variant enhances this capability further by incorporating Power over Ethernet, enabling the switch to deliver both data and power over the same cable. This feature simplifies installations of IP-based devices such as cameras, phones, and wireless access points.

All models in the X610 series support advanced Layer 2 and Layer 3 features, enabling efficient network management and control. With support for VLANs, Spanning Tree Protocol, and link aggregation, these switches facilitate better traffic management and redundancy, crucial for maintaining high availability in enterprise environments. Additionally, the ability to implement Quality of Service (QoS) ensures that critical applications receive the bandwidth necessary for optimum performance.

Energy efficiency is a hallmark of Allied Telesis products, and the X610 series is no exception. The switches incorporate technologies like Energy Efficient Ethernet (EEE), which helps reduce power consumption during periods of low network activity, thus lowering operational costs while supporting eco-friendly initiatives.

Security features are also robust, with mechanisms such as access control lists (ACLs), port security, and built-in DHCP snooping ensuring that the network remains secure against unauthorized access and threats. The switches are designed with a user-friendly interface for easy configuration and management, including support for SNMP and a web-based management interface.

In conclusion, Allied Telesis' X610 series, with its various models, offers an impressive blend of performance, scalability, and energy efficiency. These switches are well-suited for a wide variety of applications, making them an ideal choice for organizations looking to upgrade or establish a reliable networking infrastructure. Their advanced features, coupled with a focus on security and management, provide organizations with the tools necessary to handle current and future networking demands.
