The ExtremeSwitching 5520 Series is a family of high-performance, feature-rich edge and aggregation switches designed for the nextgeneration digital enterprise. The 5520 Series universal hardware provides end-to-end secure network segmentation, in addition to advanced policy capabilities, and offers a user-selectable choice of Extreme's flagship switch operating systems. This makes the 5520 a uniquely flexible platform that can be deployed across a range of edge, aggregation and wiring-closet environments. - The 5520 Series includes 24- and 48-port 1 Gigabit models, 1/2.5/5 Gigabit multi-rate models, as well as a 24-port 10 Gigabit model. The family also offers 30/60/90W Po The 5520 further supports 10G and 25G modular uplinks for flexible linkage to other switches or devices over a range of media. - Built to Suit Your Business Needs - Extreme Elements are the building blocks that allow you to tailor your network to your specific business environment, goals, and objectives. They enable the creation of an Autonomous Network that delivers the positive experiences and business outcomes most important to your organization. - Combining architecture, automation, and artificial intelligence, Extreme Elements enable you to ensure that your users get what they need - when and where they need it. Providing these superior user experiences is as simple as mixing and matching the right elements. - Universal Hardware Platform - The 5520 Series as a universal hardware platform comes with a dual-persona capability allowing user choice of the switch operating system (OS). Either the Extreme - XOS or VSP Operating System (VOSS) persona can be enabled on 5520 hardware models. The desired persona can be selected at start-up or changed at a later stage. Once selected, the 5520 assumes the features/capabilities of the selected OS.The 5520 persona activation can be done manually at bootup, including via the system CLI. Or, it can be automated by pre-provisioning the 5520 persona in Extreme - Cloud IQ. When first booted, the 5520 automatically connects to Extreme - Cloud IQ to find its persona. The pre-provisioned OS persona is then remotely enabled on the 5520 system- eliminating the need for manual selection. - Ethernet Fabric Services - The 5520 supports a variety of Ethernet Fabric services, including Extreme's Fabric Connect when running VOSS and Extreme's IP Fabric when running Extreme - XOS. It also supports Fabric Attach for automated connection to either Layer 2 or Layer 3 fabric services. Extreme's Fabric Connect and IP Fabric on the 5520 enable the creation of virtualized networks that automate network operations, simplify network provisioning and enhance security, all while reducing the strain on network and IT personnel. - Extended Edge Switching - The 5520 models support Extended Edge Switching, an innovative solution that simplifies the deployment and operation of edge switches. As the controlling bridge of an Extended Edge Switching solution, the 5520, when running EXOS, can be combined with Extreme's V300 and V400 Series access devices to create a single logical switch architecture. The result is a simplified operational model that reduces costs.
