210-AISI - Dell EMC N2128PX-ON 28-Port L3 PoE+ Switch

Dell EMC Networking N2128PX-ON: 24x GbE PoE+, 4x 2.5GbE PoE (60W), 2x 10GbE SFP+, Layer 3 managed, stackable 1U switch for enterprise campus networks.

The Dell EMC Networking N2128PX-ON (Dell SKU 210-AISI) is a 1U rack-mountable Layer 3 managed switch from the Dell N2000 series, built for modern campus network access layers. It provides 24 Gigabit Ethernet PoE+ ports for standard powered endpoints plus 4 dedicated 2.5GbE PoE ports capable of delivering up to 60W each for high-power devices such as Wi-Fi 6 access points, and 2 integrated 10GbE SFP+ ports for high-speed uplinks or aggregation. The switch supports high-availability stacking of multiple units managed from a single IP address, non-blocking wire-speed switching, and an enterprise-class Layer 2+/Layer 3 feature set including VLANs, ACLs, and static/dynamic routing. It is intended for businesses, campuses, and enterprises needing a scalable, power-efficient access switch that can power demanding PoE devices like VoIP phones, security cameras, and wireless access points while maintaining robust routing and management capability.
