EXTREME NETWORKS 4220-4MW-20P-4X – Layer 2 Cloud-Managed Ethernet Switch

Overview

The EXTREME NETWORKS 4220-4MW-20P-4X is an enterprise-grade Layer 2 wired edge access switch custom-engineered for modern corporate offices, healthcare facilities, and high-density network edge deployment sites. This cloud-managed hardware platform simplifies deployment operations by shifting system control to a unified central interface, eliminating complex, localized manual terminal configurations. It establishes rapid operational readiness for commercial spaces deploying advanced Wi-Fi 6E/7 access points, multi-stream IP surveillance networks, and high-draw IoT hardware endpoints.

The physical architecture features a 24-port multi-gigabit access configuration divided across two distinct hardware-based PoE delivery tiers. It integrates 4 multi-gigabit access ports scaling from 1G to 5GBase-T with IEEE 802.3bt Type 4 PoE++ capabilities supplying up to 90W per interface, paired alongside 20 standard 10/100/1000Base-T ports providing up to 30W of 802.3at PoE+ power. For high-speed upstream connectivity and local hardware scaling, the front panel features 4 unpopulated 1/10Gb SFP+ slot interfaces that double as native stacking ports when operating under the standard Switch Engine operating model.

Designed for automated network environments, the switch natively interfaces with ExtremeCloud IQ or ExtremeCloud IQ Site Engine, enabling zero-touch edge provisioning, real-time switch health telemetry, and automatic cloud configuration recovery. For versatile architectural placement, the low-profile 1RU chassis natively supports standard rack integration and table-mounting, including an automated silent mode operation that stops active fan rotation at ambient temperatures up to 35°C for quiet deployment settings. Avoid utilizing this system in core multi-path backbone networks running Fabric Engine where native stacking functions are inactive, or in routing setups requiring deep Layer 3 dynamic protocols.

Key Features

• Dual-tier PoE structure pairs four 90W ports with twenty 30W ports.

• 4 Multi-Gigabit ports scale up to 5Gbps to handle NextGen edge bandwidth.

• Four unpopulated SFP+ interfaces provide versatile 10Gb uplink or stacking.

• Universal cloud orchestration eliminates complex on-switch provisioning.

• Intelligent silent mode stops active cooling fan noise below 35°C.
