Product Description

Universal Edge/Aggregation Switches

The 5520 Series is a family of high-performance, feature-rich edge and aggregation switches designed for the next-generation digital enterprise. Available in 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 5520 Series provides end-to-end secure network segmentation and advanced policy capabilities that can be deployed across a range of edge, aggregation, and wiring closet environments. As a universal hardware solution, the 5520 offers a user-selectable choice of Extreme's flagship switch operating systems.

The 5520 supports 10Gb and 25Gb modular uplinks for flexible linkage to other switches or devices over a range of media. Extended Edge Switching controlling bridge is also available in support of V300/V400 edge devices, and select models offer a choice between Front to Back or Back to Front cooling. The 5520 Series offers 30W, 60W, and 90W PoE, making it an ideal wired backend for wireless APs or in support of next-gen powered Ethernet devices, such as digital signage, pan-tilt-zoom cameras, smart lighting, or point-of-sale terminals.

Network Management Flexibility
The 5520 Universal Switch series are managed by Extreme Platform ONE
or ExtremeCloud IQ from the cloud or on-premises. Alternatively, 5520 onbox management can be done manually via a web-based GUI or generic
command-line interface (CLI).

Extreme Platform ONE
Extreme Platform ONETM is an enterprise connectivity platform that
integrates networking and security with AI into one powerful and radically
simplified experience and licensing model. It supports NetOps, SecOps,
and business teams with built in automation and enables organizations to
regain control, unlock innovation, and boost productivity through:
• One integrated experience that is easy to use.
• Automation through built-in AI that boosts productivity, reducing cycle
time for many tasks from hours to minutes.
• Simplified licensing that makes the solution as easy to buy as it is to
use.
• AI-assisted workflows for configuration, deployment, and management.
• Extreme Fabric and third-party switch visualization and management
in cloud.
• Inventory management simplifies budgeting, planning and compliance.

High-Performance Stacking
The 5520 Series supports high-speed 200Gb* stacking when running
Switch Engine via its two built-in QSFP28 stacking ports. Up to eight
systems can be stacked using qualified QSFP+ direct attach cables and
optical transceivers.

Audio Video Bridging
The 5520 series supports IEEE 802.1 Audio Video Bridging (AVB) when
running Switch Engine OS. This allows 5520 models to deliver reliable, realtime audio/video transmission over Ethernet, meeting the quality of service required for today's high-definition, time-sensitive multimedia streams.

Security
Extreme Universal hardware enables the extension and enforcement of
Fabric and Universal ZTNA policies. Wherever users connect through the
network, their access is secure and segmented. ExtremeCloud Universal
ZTNA, which combines zero-trust network and application access in
one solution, automatically configures devices to enforce security policy
consistently. When used in concert with Extreme Fabric, Universal ZTNA
becomes part of the fabric services that automate segmentation and allow
the network to flex for efficiency and resiliency while keeping security
policy consistent end-to-end.

Network Fabric
The 5520 series switches support Extreme's network fabric natively for
network virtualization, automation, and network security. Extreme Fabric
is the industry's most simple, resilient, and secure end-to-end, enterprise
network fabric solution. Fabric automates discovery and onboarding of
network and user devices. Its sub-second convergence reduces unplanned
downtime and maintenance windows. Automated micro-segmentation
and stealth topology enhance and automate network security across
campus, data center, and branch. Fabric is included free with the purchase
of the 5520, no additional licenses or controllers are required.

Instant Onboarding
5520 Series onboarding to the cloud is a hands-off operation using zero
touch provisioning. Simply unpack the 5520 Series switch, connect it to
the network, and it automatically connects to the cloud, ready to be
provisioned. New switches can be configured, one-by-one, with a few clicks.
Instant port, instant secure port, and instant stack all further reduce time
spent on deployment.
