About the Extreme Networks ExtremeSwitching 5420F-48T-4XL
The ExtremeSwitching 5420F-48T-4XL is a fixed-configuration 1G campus access switch combining 48 x 1G RJ45 ports with 4 x 10G SFP+ and 2 x 40G QSFP+ uplinks in a 1U form factor. The 5420F series represents a significant advancement in programmability over its predecessors, incorporating a dedicated ARM-based application processor enabling on-box containerized application hosting via ExtremeXOS's Universal Port and App Framework. This allows third-party or custom analytics, security, and automation microservices to run directly on the switch without an external server.
The 5420F-48T-4XL supports ExtremeXOS's full enterprise feature set including Extreme Fabric Connect, MSTP, LACP, BGP, OSPFv2/v3, and VXLAN gateway functionality. Its hardware-based ACLs support granular policy enforcement at wire rate, and integration with ExtremeControl NAC enables seamless 802.1X and MAC-based posture-aware network access for both wired clients. The 5420F also supports MLAG (Multi-chassis Link Aggregation Group) for active-active uplink redundancy to dual distribution switches.
A strong option for enterprise teams deploying modern campus networks, the 5420F-48T-4XL delivers compelling operational efficiency with ExtremeCloud IQ's AI-driven lifecycle management reducing network operations labor. The switch ships in both PoE and non-PoE variants, and optional expansion modules add additional SFP+ or QSFP+ uplink capacity. It is a widely deployed access switch in commercial enterprise, K-12 education, and state and local government environments.
Ideal for
- Enterprise campus wiring closet access switching standardization
- K-12 and higher education district-wide access switch refresh
- State and local government wired access for shared services networks
- Commercial office building tenant access switching with VLAN isolation
- Mid-market enterprise branch access with cloud-managed zero-touch deployment
- MLAG-based dual-homed access switching for high availability wiring closets
