Summit X440 – Data Sheet 

2

•  8, 24, or 48-port Gigabit Ethernet (GbE) connectivity in a  

1RU form factor

•  SummitStack 40 Gbps 

•  10 Gigabit Ethernet (10GbE) uplinks

•  Identity aware policy and host integrity enforcement

•  Extensive MAC and IP security functionality to help prevent 

man-in-the-middle attacks

•  Universal Port dynamic security profile to provide fine 

granular security policy in the network

•  Multiple network edge authentication support with multiple 

endpoints per port

ExtremeXOS implementations of OpenFlow APIs allow an 

external OpenFlow-based SDN controller to access and 
control the forwarding plane of ExtremeXOS network devices. 

ExtremeXOS-based switches offer a programming interface 
through OpenFlow to enable high degree of automation in 
provisioning network services for many upper layer business 

critical applications running the OpenFlow-based SDN controller. 

Extreme XOS-based switches also allow for integration with the 

OpenStack open source cloud computing platform for public 
and private clouds through the Extreme Networks Quantum 
plugin. The plugin provides a scalable, automated, rich API-
driven system that enables networking-as-a-service model 
managing data center interconnect solutions and large multi-
tenant networks.

ExtremeXOS® supports IEEE Audio Video Bridging (AVB) 

standards to enable reliable real-time audio and video 

transmissions over Ethernet, for high-definition and time-

sensitive multimedia streams with assigned Quality of Service 
(QoS). ExtremeXOS leverages AVB to identify and reserve 
network resources for A/V traffic streams and supports 
synchronous streaming capabilities to ensure reliable and 

high-quality A/V transmissions over Ethernet. AVB also enables 
time sensitive multimedia streams to be sent over the Ethernet 

network with low latency and provides service quality for high 

definition information and entertainment applications.

Summit X440 PoE+ models support both IEEE 802.3at PoE-
plus and IEEE. 802.3af PoE. Summit X440 models that support 
PoE-plus provide a cumulative total 170 watt or 380 watt power 

budget, which can be allocated across all of the RJ45 ports on 
that particular switch.

Each of the Summit X440 models with two SummitStack 

stacking ports, provide a 40 Gigabit stacking solution. This 
stacking capability offers compatibility with other Extreme 

Networks stackable switches, including the Summit X250e, 
Summit X450a/e, Summit X460 with SummitStack module, 
Summit X480 with VIM2-SummitStack, and Summit X650 with 

VIM1-SummitStack or VIM1-10G8X – allowing up to eight units in 
a stack.

The Summit X440 models with two 10 Gigabit Ethernet (10GbE) 

links can also stack using SummitStack-V alternative stacking. 

This stacking method also offers compatibility with other 

Extreme Networks stackable switches that use 10GbE ports for 
SummitStack-V including Summit X450e, X450a, X460, X480, 

X650, X670 and X770V.

The SummitStack stacking architecture is designed for rapid 

failover capability with n-1 master redundancy, distributed Layer 
2 and Layer 3 switching, link aggregation across the stack, and 
50 millisecond failover in most cases for path failure and hitless 
master/backup failover.

• Single management point for up to eight units
• High-speed 40 Gbps stacking
• Rapid Failover for converged applications
• Can mix Summit X250e, Summit X440 Series, Summit
   X450a/e,- Series, Summit X460, Summit X480, Summit X650 and

   Summit X670 Series switches for SummitStack™ 40 Gbps stacking
