N3048ET-ON - Dell EMC 48-Port GbE L3 Switch, 2x10GbE SFP+

Dell EMC PowerSwitch N3048ET-ON: 48-port Gigabit Ethernet Layer 3 switch with 2x10GbE SFP+ uplinks, stacking, for campus and office networks.

The Dell EMC PowerSwitch N3048ET-ON is part of the N3000E Series and is designed to deliver a power-efficient, resilient Gigabit Ethernet switching solution with integrated 10GbE uplinks for advanced Layer 3 distribution in offices and campus network environments. It provides 48 RJ45 10/100/1000Mb auto-sensing ports, two dedicated 10GbE SFP+ ports, and two additional GbE combo (copper/fiber) ports, along with a hot-swap expansion module bay for optional uplink modules. Built on a non-blocking switching architecture, it offers wire-speed Layer 2 and Layer 3 performance suitable for small to medium-sized businesses and enterprise wiring closets. The switch supports high-availability stacking, redundant power options, and runs Dell EMC Networking OS6 with ONIE support for alternate network operating systems, making it a flexible, cost-effective choice for scaling network infrastructure.
