Product Overview

The Extreme Networks D2 is a high-performance Gigabit Ethernet workgroup switch with a high tolerance for environmental temperatures up to 140°F / 60°C. 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 (rack, wall, desktop, or under-tabletop), including an integral Kensington lock and an optional lock box for secure mounting.

Along with a switch capacity of 24 Gbps, the D2 provides 12 fixed 10/100/1000 Ethernet ports; two of these ports are combo ports and can be accessed via either 100Base-FX or 1 Gbps Small Form Factor Pluggable (SFP) connectors. In order to provide a reliable, high-availability network, both the standard and Power over Ethernet (PoE) D2 models support 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. The D2’s highly customizable Layer 2/3/4 packet classification capabilities together with its intelligent queuing mechanisms ensure that mission-critical applications receive prioritized access to network resources.

Making use of Extreme Networks’ policy capabilities, a network administrator can define distinct roles or profiles that represent industry-specific operational groups such as a school or a business. Each defined role is granted individualized access to specific network services and applications (e.g., administrative staff, teacher, student, guest) and these access privileges remain associated with users as they move across both wired and wireless network access points. Users are authenticated via IEEE 802.1X, MAC address, or web authentication, and then assigned a pre-defined operational role ensuring that each user has access to appropriate information, thus aligning network resource utilization with business goals and priorities. In addition, administrators can easily transition from RFC 3580 and complex ACL deployments to the Extreme Networks role-based policy framework in a seamless fashion, without the need to make changes to their RADIUS infrastructure (e.g., adding filter-ID).

In order to sustain a secure, feature-rich and cost-effective network well into the future, the D2 comes with a lifetime warranty.
