5420 Series

The 5420 Universal Switch series are managed by Extreme Platform ONE or ExtremeCloud IQ from the cloud or on-premises. Alternatively, 5420 on-box management can be done manually via a web-based GUI or generic command-line interface (CLI).

Extreme Platform ONE^TM 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.

The 5420 Series supports IEEE 802.1 Audio Video Bridging (AVB) when running Switch Engine OS. This allows 5420 models to deliver reliable, real-time audio/ video transmission over Ethernet, meeting the quality of service required for today’s high-definition, time-sensitive multimedia streams.

IEEE 802.1AE MACsec* is supported on 5420 access and built-in uplink ports, enabling the encryption and decryption of packets between connected switches or devices. As a link-only encryption, 5420 switches can still apply services to the packet, such as policy or QoS, without compromising the security of packets across the link. With 128-bit and 256-bit Advanced Encryption Standard (AES) support, the 5420 provides the most secure link encryption.

* Supported on specific hardware revisions; refer to the 5420 Hardware Installation Guide for details.

The 5420 Series supports high-speed stacking when running Switch Engine via its two built-in SFP-DD stacking ports. Up to eight switches can be stacked using qualified SFP+/SFP-DD direct attach cables and optical transceivers. Stacking is not supported when running Fabric Engine.

All 5420 models support 30W, 60W, and 90W PoE that conforms with IEEE 802.3bt. This enables the 5420 to address the needs of powered edge devices, while eliminating the need for additional electrical cabling and circuits. In addition, 5420 PoE models support perpetual and fast PoE for even more efficient and reliable powered edge device operation.

The 5420 comes with a dual-persona capability, allowing you to choose your Operating System (OS). Either the Switch Engine (EXOS) or Fabric Engine (VOSS) OS can be selected at switch start-up or changed at a later stage. When selected, the switch assumes the features and capabilities of that OS. 5420 OS selection can also be automated with Extreme Platform ONE or Extreme Cloud IQ so that the desired OS can be automatically loaded at switch start-up, facilitating remote OS enablement.

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. Extreme Cloud 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.

The 5420 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 5420, no additional licenses or controllers are required.

5420 Series onboarding to the cloud is a hands-off operation using zero touch provisioning. Simply unpack the 5420 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.

Instant Port automates adds, moves or changes across 5420 Series switch ports, eliminating the need for manual port configuration. The 5420 Series automatically detects the connected device and applies the correct port parameters. The result is significant time savings when adding or moving devices across the 5420 Series wired network. A simple cloud interface allows instant Port definitions of customer designated device types which can then be applied across a single switch, a stack or even all 5420 Series switches in the network.

*Supported via Switch Engine only

Instant Secure Port leverages ExtremeCloud Universal ZTNA for authentication and zero-trust policy enforcement across the 5420 Series switch ports, while providing the same add, move, and change automation features of Instant Port. It simplifies 5420 Series security by using Universal ZTNA’s cloud-based security capabilities, including RADIUS authentication, unified visibility and reporting, as well as policy enforced locally on 5420 Series ports. In doing so, it delivers a consistent and frictionless security experience for any user or device connecting through the 5420 Series switch. (Note: ExtremeCloud Universal ZTNA requires a separate license.)

*Supported via Switch Engine only

Instant Stack simplifies cloud-based stack provisioning, enabling the entire switch stack to be set up through a single push-button operation. Real-world stack information, including each switch model and their stack order is captured and replicated in the cloud. Once set up, the entire stack is then ready to be cloud-provisioned.
