The amazingly powerful and compact Summit X450 series is the first fixed-format switch based on the revolutionary ExtremeWare XOS core-class operating system. The Summit X450 series uses the same high-performance, non-blocking hardware technology used on Extreme's BlackDiamond 8800, continuing Extreme Networks' tradition of simplifying network deployments through the use of common hardware and software throughout the network. An extremely versatile switch, the Summit X450 is equally at home as a small network core switch, aggregation switch, high performance gigabit access switch, or as a service delivery platform for Metro Ethernet networks.Included with this compact 1RU package are 24 ports of fiber or 24 ports of copper gigabit connectivity plus option 10 gigabit uplinks. Its low-latency non-blocking design supports high throughput applications and converged voice-video-data network services. The Summit X450 series includes a versatile set of features including advanced LPM layer 3 switching normally not found in a fixed format switch, IPv6 routing, multiple supplicant Network Login, sFlow delivering traffic sampling and analysis, plus essential Metro Ethernet networking features such as vMAN tag stacking for provider bridging and granular QoS with multiple limiters per port. The versatile Summit X450 is an ideal cornerstone of any high-performance network.
