10/100/1000BASE-T ports or 100/1000 BASE-X ports. In addition, some models oer IEEE 802.3at PoE
+ ports.
Note
An extended-temperature model, 24fx-GE4, provides 24 ports of 100Base-FX. Another
extended-temperature model, 12t8fx-GE4, provides 12 ports of 10/100/1000BASE-T and eight
ports of 100Base-FX.
The ExtremeSwitching X440-G2 series switches include the following base models:

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
