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