Network switch EXTREME 4220 48-port (model 4220-48T-4X) with 48 copper ports and 4 uplink SFP+ slots

The EXTREME 4220 48-port (model 4220-48T-4X) is a rack-mountable network switch that delivers 48 copper Ethernet access ports and 4 SFP+ uplink slots for fiber or high-speed aggregation. Designed for campus and branch deployments, the switch provides standard L2 and basic L3 switching functions and supports VLAN segmentation and uplink connectivity for integration with aggregation or core layers. The unit is intended for access-layer connectivity in small to medium enterprise networks where a combination of many copper access ports and several high-speed uplinks is required.

Advantages

The EXTREME 4220-48T-4X combines a high-density 48-port copper interface with four SFP+ uplinks to simplify network consolidation and reduce cabling complexity. It supports common switching features for traffic segmentation and basic routing at the access layer, enabling straightforward integration into existing campus architectures. The rack-mount form factor and mixed copper/fiber connectivity provide flexibility for deployments that require both desktop/edge device connections and fiber aggregation to distribution or core equipment. Manufacturer-provided life-cycle estimates and emissions data are available to inform procurement decisions focused on environmental impact.

Suitable for

• Access-layer connectivity for small to medium enterprise and campus deployments
• Wiring closets and rack cabinets in branch offices
• Environments requiring many copper endpoints with fiber or 10Gbps uplinks to aggregation
• Networks requiring VLAN segmentation and basic L2/L3 switching

Key specifications

• 48 RJ45 copper Ethernet access ports
• 4 SFP+ uplink slots for fiber or 10Gbps transceivers
• Rack-mountable form factor suitable for standard 19" cabinets
• Supports L2 switching features and basic L3 functionality with VLAN segmentation
• Designed for access-layer deployment in campus and branch network topologies
• Manufacturer life-cycle assessment: estimated product life 5 years; total life-cycle CO2 emissions approx. 617.42 kg (manufacturing 51.93 kg; transportation 75.28 kg; use 495.14 kg; recycling 4.92 kg)

How to use

Install the EXTREME 4220-48T-4X in a standard 19" rack using the included mounting hardware and ensure adequate ventilation. Connect copper devices to the RJ45 access ports and install appropriate SFP+ transceivers in the uplink slots to link the switch to distribution or core equipment. Configure VLANs, access control lists, and any required L2/L3 settings through the switch management interface or your centralized controller according to your network design. Follow standard site procedures for power, grounding, and cable management.

Recommendations

For stable operation, place the switch in a temperature-controlled rack environment with proper airflow, use quality SFP+ transceivers matched to your fiber type and distance, and plan VLAN and uplink configuration to avoid overloading uplink bandwidth. Consider the manufacturer's life-cycle CO2 estimates when planning hardware refresh cycles and recycling end-of-life equipment in accordance with local regulations.
