Stack of four Dell EMC N3048ET-ON switches showing scalable enterprise network configuration with multiple units

Scalable Stack Architecture for Enterprise Growth

The N3048ET-ON's stacking capability is prominently displayed in this multi-unit configuration, demonstrating the switch's ability to scale network infrastructure efficiently. Up to 8 switches can be unified into a single logical unit, providing seamless management and enhanced redundancy across the network stack. The dedicated stacking ports ensure high-bandwidth connectivity between units while maintaining wire-speed performance. Each switch in the stack maintains its own power and cooling system while operating as part of an integrated whole. This architecture enables organizations to expand their network capacity incrementally while preserving a single point of management and consistent performance across the entire stack.

Technical Specifications

84Gbps stacking bandwidth per switch
Single IP management for up to 8 switches
Non-blocking architecture for full wire-speed performance
