Enterasys B5G124-48P2 B5 48 Port PoE Managed Gigabit Stackable Network Edge SwitchB5G124-48P2Includes:48 10/100/1000 PoE4 Combo SFP Ports2 Dedicated Stacking PortsDB9 Console PortOverview: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 multilayer switching capabilities and support for high density 10/100/1000 Ethernet ports, cost effective10GE uplinks, dual IPv4/IPv6 management, basic routing and policy-based automation capabilities for advanced edge deployments.Future-proofed with 802.3at high-power PoE supportAutomatic discovery and deployment of VoIP servicesHigh-availability stacking assures reliable network operationsAutomated management features reduce operational costsInvestment protection via comprehensive lifetime warranty1.47 Tbps capacity and 809.5 MppsThe 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 highly-scalable architecture and a comprehensive 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.Extreme Networks B5 stackable switches address emerging business application needs such as automatically supporting voice, video and unified communications at an attractive price point.
