The Extreme Networks X440-G2-48P-10GE4 is a high-performance, scalable edge switch designed for modern enterprise networks. This 48-port Gigabit Ethernet switch delivers advanced Layer 2 and Layer 3 capabilities with Power over Ethernet Plus (PoE+) support, providing up to 30W per port for connected devices. Featuring four upgradable 10GbE SFP+ ports, flexible stacking options, and robust security features, this switch offers reliable connectivity and management for demanding network environments.

• 48 x 10/100/1000BASE-T PoE+ ports with IEEE 802.3at support
• 4 x 1GbE SFP uplink ports upgradable to 10GbE via software license
• Up to 740W PoE+ power budget with optional redundant power supply
• SummitStack-V technology for stacking up to 8 switches
• Advanced security with role-based policies and ACLs
• ExtremeXOS operating system with cloud management capability

• High-density PoE+ design supports power-intensive devices
• Software-upgradable uplinks for future-proof investment
• Non-blocking architecture with 176 Gbps switching capacity
• Energy Efficient Ethernet (EEE) for reduced power consumption
• Comprehensive QoS with 8 egress queues per port
• Audio Video Bridging (AVB) support for real-time media
• Extended temperature models available for harsh environments

The X440-G2 series switches leverage Extreme Networks' ExtremeXOS operating system, providing advanced networking protocols including IEEE 802.1Q VLANs, IEEE 802.3ad Link Aggregation, and IEEE 802.1AB LLDP. The switches support IPv4 and IPv6 routing, MPLS, and comprehensive security features including MACsec encryption. The SummitStack-V technology enables virtual stacking of up to 8 switches using standard 10GbE optics and cabling.

The X440-G2-48P-10GE4 operates as a fully managed Layer 3 switch, processing packets through hardware-based forwarding engines. The switch utilizes store-and-forward architecture with jumbo frame support up to 9216 bytes. Traffic is classified and prioritized through 8 egress queues per port, with granular rate limiting at 8 Kbps increments. PoE+ power management is handled through integrated power controllers that monitor and allocate power to connected devices based on IEEE 802.3at standards.

This switch is ideal for enterprise edge deployments, campus networks, and converged environments requiring high-power PoE+. Typical applications include:

• Enterprise wiring closets with VoIP phones and wireless access points
• Educational institutions with digital classroom technology
• Healthcare facilities supporting medical devices and communication systems
• Retail environments with POS systems and surveillance cameras
• Industrial settings with extended temperature requirements

• Superior PoE+ density with full 30W power on all 48 ports
• Future-proof design with software-upgradable 10GbE uplinks
• Advanced stacking technology reduces management complexity
• Comprehensive security policy enforcement with role-based access
• Energy Efficient Ethernet reduces power consumption by up to 50%
• Five-year limited warranty with advanced hardware replacement

Q: Can the 1GbE SFP ports be upgraded to 10GbE?

A: Yes, the four SFP uplink ports can be upgraded to 10GbE operation through a software license, providing flexible uplink options without hardware replacement.

Q: What is the maximum PoE power budget?

A: The internal power supply provides 740W of PoE power. With an external redundant power supply (RPS), the total available PoE power increases to 1440W.

Q: How many switches can be stacked together?

A: Up to 8 X440-G2 switches can be stacked using SummitStack-V technology, with support for mixed stacking with other Extreme X-Series switches running the same ExtremeXOS version.

Q: Does this switch support cloud management?

A: Yes, select X440-G2 models including the 48P-10GE4 can be managed through ExtremeCloud, providing a single-pane management solution for both wired and wireless networks.

• Ensure adequate airflow and clearance around the switch for proper ventilation
• When using PoE+ at full capacity, consider ambient temperature derating
• Extended temperature models (0°C to 60°C) do not support 10GbE upgrades or stacking
• For 10GBASE-T SFP+ transceivers, populate every other port and leave adjacent ports unused
• Verify compatibility of third-party SFP/SFP+ modules before deployment
• Follow proper ESD precautions during installation and maintenance
