Extreme Networks X440-G2-48p-10GE4 | 48-Port Gigabit PoE+ Ethernet Switch
The Extreme Networks X440-G2-48p-10GE4 is a high-density, enterprise-grade PoE+ switch designed for demanding network environments. This powerful switch features 48 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 full PoE+ support (30W per port), SummitStack-V stacking, and cloud management via ExtremeCloud™.
Key Features
- 48 x Gigabit Ethernet RJ-45 PoE+ ports (30W per port) + 4 x SFP uplink ports (upgradable to 10GbE)
- 740W total PoE budget with support for IEEE 802.3af/at devices
- 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™
- Energy Efficient Ethernet (802.3az) for reduced power consumption
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-G2-48p-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 enterprise wireless deployments, IP surveillance systems, VoIP implementations, and converged network environments. Supports power delivery to wireless access points, IP phones, security cameras, and other PoE-enabled devices. The high port density and PoE+ capability make it suitable for wiring closets, network aggregation points, and medium to large business environments requiring both data and power over Ethernet.
