Extreme Networks Data Sheet: Summit X450a Series

Advanced Features Oer Versatile Deployment

Combining superior resiliency, comprehensive security, and nonblocking performance, the Summit X450a switch is the

cornerstone of a high-performance network. Summit X450a series provides a high bandwidth, non-blocking architec-

ture with tri-speed copper Gigabit Ethernet ports for demanding Top-of-Rack data center applications. With optional

10 gigabit trunks, Summit X450a switches connect to gigabit edge devices and provide a high-performance aggrega-

tion layer in a traditional three-tier LAN. For Carrier Ethernet networks, Summit X450a switches deliver exceptional

QoS and trac management capabilities.
