Chapter 1: Overview

Power Supplies

The 8100L Series switches have one AC power supply. The 8100S Series switches have two AC or DC power supplies, except for the AT-8100S/ 24C Switch, which has one AC power supply. The supplies are not field- replaceable and each has a separate AC or DC connector on the back panels.

Only one power supply is active at a time in non-PoE 8100S Series switches. The second power supply operates in a redundant state and is automatically activated by the switch if the active power supply loses power or fails. The change over is instantaneous, making it transparent to the network users. Power redundancy is available only when both AC connectors on the switch are connected to power sources.

For all operations excluding PoE, the dual power supplies in the AT-8100S/24POE and AT-8100S/48POE Switches operate in the same manner as those in the non-PoE switches. One power supply operates in an active state while the other resides in a redundant state.

For PoE, however, the power supplies operate in a load-sharing manner, with each power supply providing 185 watts, half the total PoE budget of the switch. The maximum 370 watts power budget of PoE is only available when both power supplies are connected to power sources.

Refer to “Technical Specifications” on page 107 for the input voltage range.

Allied Telesis is renowned for its range of high-performance networking solutions, and the AT-8100 series exemplifies their commitment to innovation in the network switch market. Designed for small to medium-sized businesses, the AT-8100L and AT-8100S series includes several versatile models: AT-8100L/8POE, AT-8100L/8POE-E, AT-8100L/8, AT-8100S/48, and AT-8100S/48POE. These products combine advanced features with user-friendly management tools, making them ideal for various applications.

One of the standout features of the AT-8100 series is its Power over Ethernet (PoE) capabilities, particularly in models like the AT-8100L/8POE and AT-8100S/48POE. These switches can deliver power to connected devices, such as IP cameras, wireless access points, and VoIP phones, over the same cabling that carries data. This simplifies installations and can reduce infrastructure costs, as there’s no need for additional power sources for each device.

The AT-8100L/8POE and AT-8100L/8POE-E are equipped with 8 Ethernet ports, with the PoE models supporting up to 15.4W per port on the standard. The AT-8100S/48 boasts an impressive 48 ports, making it suitable for high-density environments. All units in the series are designed to handle Layer 2 networking protocols, ensuring reliable and swift data transfer within local area networks.

Management features are robust and user-friendly. The switches support both web-based and command-line interface management, allowing network administrators to tailor their control methods according to preference and familiarity. The AT-8100 series includes features such as VLAN support, quality of service (QoS) settings for traffic prioritization, and link aggregation for increased bandwidth and redundancy.

Security is a critical aspect of modern networking, and Allied Telesis addresses this with features like port security and DHCP snooping. These functionalities help prevent unauthorized access and protect the network from various types of attacks.

In summary, the Allied Telesis AT-8100 series switches, including the AT-8100L/8POE, AT-8100L/8POE-E, AT-8100L/8, AT-8100S/48, and AT-8100S/48POE, provide a blend of PoE capabilities, robust management features, and solid performance. Their reliability and ease of use make them an excellent choice for businesses looking to enhance their network infrastructure. As organizations increasingly rely on connected devices, the AT-8100 series equips them with the necessary tools to build efficient and secure networks.
