Essential details：X440-G2-24fx-GE4 X440-G2 Series Switch Quick Reference
The X440-G2 Series is a scalable, cost-effective family of stackable edge switches designed for campus edge applications. Each X440-G2 model is powered by one of Extreme’s flagship operating systems, ExtremeXOS, a resilient OS providing continuous uptime as well as manageability and operational efficiency to the campus edge. The X440-G2 Series switches provide high-performance routing and switching, flexible stacking, PoE support, and comprehensive security.
Available in 12, 24, and 48-port Gigabit Ethernet models with options for SFP and 100BASE-FX fiber models, the X440-G2 Series enable fine-grained control over traffic flows as well as controlled access to network services and applications by supporting intelligent Layer 2 switching and Layer 3 IPv4 or IPv6 routing, as well as a role-based access policy, bi-directional Access Control Lists, and granular ingress and egress bandwidth control.

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
- 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 X440-G2 switches, SummitStack-V is compatible with X450-G2 and X460-G2 switches with 10 Gb uplinks and with X620, and X670-G2 switches running the same version of ExtremeXOS. SummitStack-V enabled 10 GbE ports must be physically direct-connected.
