Summit X250e series switches are based on 
Extreme Networks

 

revolutionary ExtremeXOS 

core-class operating system. ExtremeXOS is a 
highly resilient, modular operating system that 
helps provide continuous uptime, manageability 
and operational efficiency at an affordable price. 

Summit X250e provides high availability and 
performance with its advanced traffic management 
capabilities. Summit X250e supports the large- 
scale rollout of a converged network with devices 
such as IP telephones, wireless access points 
and other devices that require power from a LAN 
connection. Summit X250e-24x supports carrier 
Ethernet edge deployment with its flexible fiber 
connectivity options. Summit X250e-24x can 
support 100BASE-FX, 100BASE-LX10 and 
100BASE-BX on its SFP ports depending upon 
deployment requirements. 

Summit X250e supports hardware-based routing 
for both IPv4 and IPv6 to help provide investment 
protection by allowing the rollout of IPv6 in your 
network now or in the future. 

The highly flexible Summit X250e switch provides 
high-density Fast Ethernet ports plus dedicated 
40 Gbps high-speed stacking ports in a compact 
1RU format, supporting a full range of Layer 2 to 
Layer 4 functionality on every port for high 
productivity. Optional redundant power supplies 
are available with each switch to help secure 
against power anomalies.
