5C1J6 - Dell EMC N2128PX-ON 28-Port Layer 3 PoE+ Switch

Dell EMC Networking N2128PX-ON managed Layer 3 switch: 24 PoE+ GbE ports, 4 multi-gig PoE ports, 2x 10GbE SFP+ uplinks for power-efficient network edge deployments.

The Dell EMC Networking N2128PX-ON (Dell part number 5C1J6) is a Layer 3 managed Gigabit Ethernet switch from the Dell EMC PowerSwitch N2000 Series. It is designed as a power-efficient network-access switch with integrated 10GbE uplinks, intended for enterprise wiring closets and network edge deployments that require high-density PoE. The switch provides 24 auto-sensing 10/100/1000 PoE+ ports, four multi-gigabit (100/1000/2.5G/5G) PoE ports, and two 10 Gigabit SFP+ uplink ports, plus two dedicated stacking ports. It runs Dell EMC Networking OS6, offering a familiar command-line interface, Layer 2/3 switching, VLAN support, ACLs, and stacking of up to 12 switches from a single management IP. Its non-blocking architecture, wire-speed switching, and integrated 1000W power supply make it suitable for connecting Wi-Fi 6/6E access points, IP cameras, and other bandwidth- and power-intensive endpoints.
