Product Name

B-Series B5 Switch 48 ports

UPC

647030018041

Overview

The B5 incorporates the new 802.3at high-power PoE on all ports, translating into increased power provisioning for power-hungry devices such as Pan/Tilt/Zoom (PTZ) IP surveillance cameras, IP videophones, third party 802.11n access points and virtual desktops. 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. A highlyscalable architecture and a comprehensive limited lifetime warranty ensure that a B5 network investment will sustain a secure, feature-rich and cost-effective network well into the future.

The B5’s highly customizable Layer 2/3/4 packet classification capabilities work together with the 8 hardware-based priority queues associated with each Ethernet port to support a suite of differentiated services with as many as 8 distinct priority levels to provide guaranteed Quality of Service (QoS) for critical voice and video network traffic. In conjunction with its non-blocking L2 switching and L3 routing architecture, the B5’s intelligent queuing mechanisms ensure that mission-critical applications receive prioritized access to network resources
