manual abstract
Support for jumbo Ethernet frames enables higher throughput of time sensitive data. Environmentally Friendly ECO-Switch In keeping with our commitment to environmentally friendly processes and products, the AT-9000/28 is the first of our new green range of products designed to reduce power consumption, minimize hazardous waste and even reduce office noise pollution. Among many features including the use of high efficiency power supplies, and low power chipsets we have also included an ECO-Switch button on the front panel of the AT-9000/28 switch.This allows you to conserve additional power by turning off the port and MODE LEDs when they are not required. Low Power Consumption with Near Silent Operation Specifically designed to be usable in a classroom or retail store environment the AT-9000/28 uses the latest in low power technologies to minimize power consumption and operational noise. Ideal Branch Office and Wiring Closet Connectivity Powerful line rate performance makes this switch ideal for branch offices or the wiring closet of larger offices.The state-of-the art QoS capability of this product ensures reliable delivery of advanced network services such as voice and video, while effectively controlling the continually increasing traffic needs found in today’s networks. Easy Access Networking Featuring an industry standard CLI and Allied Telesis’ intuitive featured Web interface the advanced features of the AT-9000/28 are accessible to a wide range of system administrators.The well known CLI and Web interfaces significantly reduce learning time and minimize the cost of deployment. Secure Management Only authorized administrators can access the management interface of the AT-9000/28. Protocols such as SNMPv3 facilitate this protection of your network with local or remote connections. Securing the Network Edge To ensure the protection of your data, it is important to control access to your network. Protocols such as IEEE 802.1x port-based authentication guarantee that only known users are connected to the network. Unknown users who physically connect can be isolated to a predetermined part of your network offering guests such benefits as Internet access while ensuring the integrity of your private network data.
