Extreme Networks X440-G2-12p-10GE4 | 12-Port Gigabit PoE+ Ethernet Switch

The Extreme Networks X440-G2-12p-10GE4 is a compact yet powerful PoE+ switch designed for space-constrained network environments. This efficient switch features 12 x 10/100/1000BASE-T PoE+ ports, 4 x 1GbE SFP ports upgradeable to 10GbE via software license, and comprehensive Layer 2/3 capabilities. Built on the robust ExtremeXOS operating system, it offers advanced features including PoE+ support, SummitStack-V stacking, and cloud management via ExtremeCloud™, making it ideal for small to medium deployments.

Key Features

• 12 x Gigabit Ethernet RJ-45 PoE+ ports + 4 x SFP uplink ports (upgradable to 10GbE)
• 200W total PoE budget with support for IEEE 802.3af/at devices
• Compact 1RU form factor ideal for space-constrained environments
• ExtremeXOS OS with advanced security and management features
• Support for SummitStack-V technology (up to 8 switches)
• Role-based policy enforcement and cloud management via ExtremeCloud™

Technology & Standards

The X440-G2 series switches support a comprehensive range of IEEE standards including 802.3ab (1000BASE-T), 802.3z (1000BASE-X), 802.3ae (10GBASE-X), 802.3at (PoE+), and 802.3az (Energy Efficient Ethernet). These advanced switches also feature sophisticated security protocols, QoS mechanisms, and support for Audio Video Bridging (AVB) on select models, making them ideal for converged network environments.

How It Works

The X440-G2-12p-10GE4 operates at both Layer 2 and Layer 3, providing advanced routing, switching, and policy-based traffic management. It utilizes hardware-based forwarding engines to deliver low-latency performance with less than 4 microseconds latency for 64-byte packets. The switch supports advanced features like granular bandwidth control (8 Kbps increments), 8 QoS egress queues per port, and comprehensive ACL support for precise traffic management. The integrated PoE+ controller intelligently manages power allocation to connected devices.

Applications

Ideal for small to medium business environments, retail locations, branch offices, and classrooms. Perfect for powering wireless access points, IP phones, security cameras, and other PoE-enabled devices in space-constrained environments. The compact form factor makes it suitable for wall-mounted installations, small network racks, and locations where physical space is limited but PoE capability is required.
