Extreme 5420M-48T-4YE Switch

Key Features of the Extreme 5420M-48T-4YE

Universal Hardware Platform with Dual Persona Capability

The 5420M 48T 4YE represents Extreme Networks’ next generation digital enterprise solution, featuring a revolutionary universal hardware platform that provides dual persona capability. This advanced switch allows users to select between ExtremeXOS (Switch Engine) or VOSS (Fabric Engine) operating system personalities at startup or change them at a later stage through zero touch provisioning. The user selectable choice of operating systems enables seamless integration into existing network infrastructures while providing advanced policy capabilities for comprehensive network segmentation and security management.

High Performance Stacking and Connectivity Architecture

Featuring 48 port x 10 100 1000base T connectivity with built in uplink ports, the Extreme Networks 5420M delivers exceptional forwarding rate performance and switching capacity. The switch includes four high speed stacking capable SFP28 uplink ports supporting 1/10/25Gb speeds, plus two additional SFP DD ports for high performance stacking configurations. This architecture supports connected switches in stack configurations while maintaining efficient management through ExtremeCloud IQ cloud-based or on-premises solutions, enabling comprehensive network access and management across distributed environments.

Advanced Security and Encryption Capabilities

The switch incorporates most secure link encryption through IEEE 802.1AE MACsec support on all access ports and built-in uplink ports, providing secure link encryption for today’s high definition audio video applications and time sensitive multimedia streams. With comprehensive ACL support and port based QoS capabilities, the 5420M 48T ensures reliable security for wireless APs, digital signage, smart lighting systems, and point of sale terminals while supporting audio video bridging protocols for demanding multimedia environments.

Modular Design with Field Replaceable Components

Built for wiring closet environments, the switch features field replaceable power supply modules and modular fan systems that eliminate the need for additional electrical cabling during service operations. The design supports external USB type A and USB micro-B connections for configuration management, while the advance parts replacement program ensures minimal downtime. Unlike models with fixed power supply configurations, the 5420M series enables hot-swappable component replacement without requiring complete system shutdown, making it ideal for powered edge devices that demand continuous availability.

Hardware Architecture

Power and Environmental Specifications

The field replaceable power supply architecture supports dual redundant PSU configurations with two unpopulated modular PSU slots. Power consumption varies based on configuration and optical transceivers selection, with efficient power management for devices ranging from wireless APs to high-power applications. The switch operates within standard temperature ranges and meets industry compliance standards for wiring closet environments. Fan modules provide adequate cooling while maintaining low noise levels suitable for office and enterprise deployments.

Software and Operating System Support

The 5420M 48T 4YE supports both ExtremeXOS (Switch Engine) and VOSS (Fabric Engine) operating system personalities through its universal hardware platform design. Base software license includes comprehensive Layer 2 switching capabilities, VLAN support, and advanced policy features. The switch includes one-year ExtremeCloud IQ Pilot subscription for cloud-based management, zero touch provisioning, and remote configuration capabilities. Web based GUI and command-line interface options provide flexible management approaches for different end user needs and technical skill levels.

Connectivity and Expansion Options

All 48 ports support x 10 100 1000base T connectivity with auto-sensing full and half duplex operation, though half duplex mode is not supported at Gigabit speeds. The four SFP28 uplink ports accommodate various optical transceivers for fiber connectivity, while the two SFP DD ports enable high speed stacking or additional uplink capacity. The switch supports both twisted pair and optical fiber media types, providing flexibility for diverse network infrastructure requirements and enabling connection to a wide range of powered edge devices.

Model Comparison Within 5420 Series

The 5420M 48T 4YE represents the non-PoE variant within the 5420M family, distinguishing it from the 5420M-48W-4YE which includes 802.3bt 90W PoE capability. Compared to 5420F models that feature fixed power supply designs, the 5420M series provides field replaceable power supply options and supports higher-speed 25Gb uplink capabilities. The 48 port configuration offers maximum density while maintaining the same universal hardware platform advantages and dual persona capability found across the entire 5420 series range.
