Summit48 Data Sheet

As the industry's first Enterprise Desktop Switches, Summit48™ and Summit24™ integrate seamlessly into the enterprise LAN while delivering the most sought-after enterprise features, high port-density, wire-speed performance and low cost of ownership.

Summit48. With 48 switched 10/100 Mbps autosensing Ethernet ports and two full-duplex GBIC-based 1000BASE-SX or LX Gigabit Ethernet ports, Summit48 has a 17.5 Gbps non-blocking switch fabric and a forwarding rate of 10.1 million packets per second. Summit48 comes with wire-speed Layer 2 and wire-speed basic Layer 3 switching using static routing or RIP V1/V2 routing protocols. For easy scalability, the Summit48 upgrades to full Layer 3 switching with a simple upgrade key. The full Layer 3 switching includes support for enterprise protocols such as OSPF, DVMRP, PIM and IPX routing of multiple encapsulation types.

Pre-installed on every Extreme Networks switch, the ExtremeWare™ software suite combines industry-standard protocols that provide interoperability with legacy switches and routers, plus Policy-Based Quality of Service (QoS) for bandwidth management and traffic prioritization in today's enterprise networks.


Simple to Deploy, Easy to Manage
The high-density 10/100 Mbps autosensing Ethernet ports in these switches simplify deployment and minimize complexity at the desktop. There's no need to change any existing subnet structures. Both the Summit48 and Summit24 come equipped with wire-speed Layer 2 switching and wire-speed basic Layer 3 switching that supports static routing and use of the RIP protocol. Using a system-specific upgrade key, network managers can migrate anytime to full Layer 3 switching including support for enterprise protocols such as OSPF, DVMRP, PIM and IPX routing of multiple encapsulation types.

The ExtremeWare standards-based software suite also simplifies switch management. Preloaded on every Summit switch, ExtremeWare includes a comprehensive command line interface (CLI) and the easy-to-use ExtremeWare Vista™ Web-based management interface. ExtremeWare also supports SNMP and four groups of RMON.

A Future-Proof Solution
With Summit48 and Summit24, Extreme has taken the features and performance of an enterprise switch, the simplicity and low cost of a workgroup hub, and deployed them in a stackable 3½ inch-high form factor. Included with this powerful price/performance mix are port trunking, wire-speed Layer 2 switching, wire-speed basic Layer 3 switching and quality of service -- everything a business needs for today's switched enterprise LANs.

For future proofing and enterprise applications, network managers can easily upgrade their switches at any time to include support for enterprise protocols such as OSPF, DVMRP, PIM and IPX routing of multiple encapsulation types. As part of Extreme's scalable, end-to-end LAN switching solutions, both the Summit48 and the Summit24 give businesses the ability to handle the most bandwidth-intensive applications in the future.

Maximum Performance & Scalability
Extreme's Enterprise Desktop Switches maximize performance and scalability for a wide range of desktop connections. They can provide dedicated 10/100 Mbps links to every desktop or multiple 10/100 or 1000 Mbps links can be trunked to load-share power-user traffic. They also support dual load-shared down links to the rest of the network.

Like other Summit switches, Summit48 and Summit24 are non-blocking so their backplane capacity is always greater than the aggregation of all their ports. This enables full wire-speed performance on all ports, all the time - even under severe traffic conditions. In addition, a low over-subscription ratio of 2.4:1 lets the Summit48 and Summit24 handle the traffic demands of individual users and high-performance workgroups.

Lower Total Cost of Ownership
Low cost is an important factor when considering switching to the desktop. And the combination of low cost, high port density and wire-speed performance make Summit48 and Summit24 the ultimate choice for Enterprise Desktop Switching.
