N-series is a family of energy-efficient and cost-effective 1GbE and 10GbE switches designed for modernizing and scaling network infrastructure. The Dell Networking N3000 series offers high-availability GbE switches for Layer 3 access or aggregation, providing easy-to-manage solutions. The Dell Networking N3000 series has Power-over-Ethernet Plus (PoE+) without an external power supply. This allows you to attach devices with high power requirements (up to 30.8 watts) without running a separate power cable. PoE+ is particularly useful in older buildings where installing power to multiple, widespread locations can be prohibitively expensive.
