Extreme networks Summit X450a-48t 16157 Data Sheet

The Summit X450a series is based on  
Extreme Networks

®

 revolutionary ExtremeXOS 

OS. ExtremeXOS modular OS is a highly resilient 
OS that provides continuous uptime, manageability 
and operational efficiency. Each Summit X450a 
switch offers the same high-performance, non-
blocking hardware technology used on  
Extreme Networks BlackDiamond

®

 8800 series, in 

the Extreme Networks tradition of simplifying 
network deployments through the use of common 
hardware and software throughout the network.  

The highly flexible and scalable Summit X450a 
switch is an ideal aggregation switch for traditional 
small core enterprise networks. The Summit X450a 
series is a perfect first level aggregation device for 
DSLAMs at a local central office before traffic is 
passed on to the Extreme Networks  
BlackDiamond 20808 or BlackDiamond 20804 
core switch at the Point of Presence (POP) where 
traffic is managed and connected to service networks.  

The extremely versatile Summit X450a switch 
provides high-density gigabit plus optional 10 
Gigabit Ethernet ports in a compact 1RU format, 
supporting a full range of Layer 2 to Layer 4 
functionalities on every port to allow high 
productivity. Optional redundant power supplies 
are offered with each switch to protect against 
power anomalies, providing a continuous opera-
tional network.
