Product Overview
The ExtremeSwitching X440-G2 series is a scalable cost-eective family
of edge switches powered by Extreme Networks ExtremeXOS, a highly
resilient OS providing continuous uptime, manageability and operational
eciency. The X440-G2 series switches provide high-performance routing
and switching, flexible stacking, PoE-plus support and comprehensive
security, while extending the benefits of ExtremeXOS to the campus edge.
The X440-G2 Series easy-to-use, yet powerful, management services
include role-based policies for controlled access to specific network
applications. Select X440-G2 Series switches can also be cloud-managed
via ExtremeCloud™, Extreme Networks innovative single-pane subscriptionbased management solution.
Intelligent Switching
The X440-G2 Series supports sophisticated and intelligent Layer 2
switching, as well as Layer 3 IPv4/IPv6 routing. They also support rolebased policy capabilities, Provider Bridges, bidirectional Access Control
Lists, as well as granular (8 Kbps) ingress/egress bandwidth control.
Altogether, these enable fine-grained control over trac flows, as well as
controlled access to specific network services and application.

Flexible 10GBE Port Upgrades
All X440-G2 base models come equipped with 4 upgradeable 1GbE ports,
resident on either the faceplate or rear panel of each model. These 1GbE
ports can be upgraded to 10GbE Ethernet via a simple software license.
This gives administrators the option to increase switch uplink speeds
without replacing the entire switch.

Page 2
Notes: 10GbE upgrades are not supported on extended
temperature models. The two rear-panel 1GbE copper combo ports
on the 48 port switches become 10GBase-T ports when either
10GbE license is applied to the rear-panel SFP/SFP+ ports.
High-Performance Stacking
ExtremeXOS SummitStack-V capabilities allow up to eight
X440-G2 switches to be stacked together via two of the
native X440-G2 stacking ports. SummitStack-V allows use
of standard 10Gb Ethernet cabling and optics technologies,
providing longdistance stacking connectivity of up to 40
Km while eliminating the cable complexity of non-standard
stacking options. X440-G2 switches can be stacked with
other X450-G2, X460-G2, X670-G2 and X770 switches via
SummitStack-V so long as all are running the same version
of ExtremeXOS.
Note 1: SummitStack-V uses two of the four available uplink ports
on the X440-G2 and runs a 10Gb non-Ethernet stacking protocol.
These stacking ports DO NOT require a 10GbE software license, and
can take full advantage of standard SFP+ transceivers.
Note 2: Extended temperature range switches do not
support stacking.
IEEE 802.3AT Poe-Plus
X440-G2 Series switches support both IEEE 802.3at
PoE-Plus and IEEE 802.3af PoE to enable connection
of standards compliant PoE devices today and into the
future. Power over Ethernet allows connection of Ethernetpowered devices, such as wireless access points, Voice over
IP phones, and security cameras. The X440-G2 can also
support full PoE-Plus 30W power across all 48 ports with
an external redundant power supply (RPS).
Role-Based Policy
The X440-G2 supports role-based policies that can be
centrally administered through the ExtremeManagement
(formerly Netsight) policy manager. This policy framework
empowers network administrators to define distinct roles
or profiles to represent industry-specific operational groups
that may exist in an education or a business environment
(e.g., administrator, teacher, student, guest). Each defined
role can then begranted individualized access to specific
network services and applications and these access
privileges remain associated with users as they move across
both wired and wireless network access points.
ExtremeCloud™ Management
Provides a single plane of glass for cloud managing both
the wired and wireless components of your network. Zero
touch provisioning also significantly reduces deployment
times. Select X440-G2 models have been enabled for use
with ExtremeCloud. See the ExtremeCloud Data Sheet
for details.
USB 2.0 Support
All X440-G2 switches have a USB 2.0 port that is supported
as a port to a storage device for all EXOS versions of 22.1
or higher.
Extended Temperature Range Support
The X440-G2 include three switch models that support 0°C
to 60°C operating range (Models 16539, 16540 and 16541)
to address the unique environmental needs of specific
industries and/or locations.
Comprehensive Security Management
The X440-G2 provides comprehensive security, including:
• User policy and host integrity enforcement, and
identity management.
• Universal Port Dynamic Security Profiles for fine
granular security policies across the network.
• Threat detection and response instrumentation to react
to network intrusion.
• Denial of Service (DoS) protection and IP security
against man-in-the-middle and DoS attacks.
These features ensure both the security of the network and
of users accessing the network.
Audio Video Bridging (AVB)
The X440-G2 series supports IEEE 802.1 Audio Video
Bridging to enable reliable, real-time audio/video
transmission over Ethernet. AVB technology delivers the
quality of service required for today’s high-definition and
time-sensitive multimedia streams.
Note: Only 24 ports on either the 24 or 48 port models
support AVB.
Ordering Notes
All X440-G2 switches ship with fixed fans and
power supplies:
• All the X440-G2 switches support optional external
redundant power supplies (RPS).
• The following three switch models that support 0C to
60C are NOT upgradeable to 10GbE:
• X440-G2-24fx-GE4
• X440-G2-12t8fx-GE4
• X440-G2-24t-GE4

Note: SummitStack-V stacking is enabled on two of the four
X440-G2 uplink ports by default (no license required). All stacking
ports operate at 10Gb,but do not use standard Ethernet protocols.
X440-G2 uplink ports, when not used for stacking, run the standard
Ethernet protocol. Non-stacking uplink ports are limited by default
to 1GbE, unless upgraded via software license. 10GbE licenses are
available, in both two- and four-port versions, as well as a license to
upgrade a dual 10GbE uplink switch to a four 10GbE uplink swiitch,
that enable X440-G2 uplink ports to run the 10Gb
Ethernet protocol.
