- 48 x 10/100/1000 + 4 x shared SFP
The Extreme Networks B5 is a scalable, high-performance Gigabit Ethernet switch that provides support for the bandwidth-intensive and latency-sensitive requirements of today's demanding business applications. The B5 is an excellent choice for environments that require complete multi-layer switching capabilities and support for high density 10/100/1000 Ethernet ports, cost effective uplinks, dual IPv4/IPv6 management, basic routing and policy-based automation capabilities for advanced edge deployments. The B5 incorporates 802.3at high-power PoE on all ports, translating into increased power provisioning for power-hungry devices. Built-in high-power PoE support is a cost effective alternative for customers in place of purchasing separate PoE midspans, which can take away valuable rack space, add cost and contribute more cabling to the wiring closet. The B5 provides high port density in a 1U footprint and is environmentally friendly by design. The B5's overall energy efficiency is further enhanced by a low current draw and an extreme tolerance for high environmental temperatures.
