• ExtremeSwitching X440-G2-48t-10GE4-DC switch
• ExtremeSwitching X440-G2-12t8fx-GE4 switch
• ExtremeSwitching X440-G2-24fx-GE4 switch
• ExtremeSwitching X440-G2-24t-GE4 switch
Most X440-G2 switches support both half-duplex and full-duplex communication over
10/100/1000BASE-T ports. For details, see the "Switch Ports and Slots" topics for the individual base
models.
All models come equipped with four ports of SFP 1 GbE resident on either the faceplate or rear panel.
On the 12-port, 24-port, and 48-port 10/100/1000 models, except for the extended-temperature
models, these 1 GbE ports can be upgraded to 10 Gb SFP+ Ethernet through software licensing. The 24-
and 48-port 10/100/1000 models (except the X440-G2-24t-GE4) have four 1 GbE SFP combination
ports on the front panel.
ExtremeSwitching X440-G2 series switches require ExtremeXOS version 21.1.1 or later.
Security
These switches provide comprehensive security management:
• User policy and host integrity enforcement, and identity management
• Universal Port Dynamic Security Profiles to provide fine granular security policies in the network
• Threat detection and response instrumentation to react to network intrusion with CLEAR-Flow
Security Rules Engine
• Denial of Service (DoS) protection and IP security against man-in-the-middle and DoS attacks to
harden the network infrastructure
Stacking
Up to eight X440-G2 switches can be stacked using SummitStack-V. Each X440-G2 unit (except the
extended temperature range switches) comes equipped with two stacking ports using an SFP+
interface. Standard 10 Gb Ethernet Optics and passive and active cables can be used in the SFP+ ports
for stacking X440-G2s together using SummitStack-V.
ExtremeXOS supports the SummitStack-V capability using two SFP+ ports as stacking ports, enabling
the use of standard cabling and optics technologies used for 10 GbE SFP+. SummitStack-V provides
long-distance stacking connectivity of up to 40 km while reducing the cable complexity of
implementing a stacking solution. For a list of X440-G2 ports that can be used with SummitStack-V, see
X440-G2 Stacking on page 196.
