The Extreme Networks D2 is a high-performance Gigabit Ethernet workgroup switch with a high tolerance for a wide range of environmental temperatures. With fans that only operate at extreme temperatures, the D2's very quiet design makes it an ideal solution for classrooms and conference rooms, as well as warm locations with limited ventilation. By providing LEDs on the front, back, and top of the switch, the D2 offers very flexible mounting options. In order to provide a reliable, high-availability network, it supports redundant, external power bricks as well as Link Aggregation Groups (LAGs) for scalable, redundant uplinks. In conjunction with its non-blocking architecture, the D2's robust Quality of Service (QoS) features enable strong support for converged multimedia networks, including Voice over IP (VoIP), video, as well as all types of data-intensive applications.
