Extreme Networks X440-G2 48-Port Managed Gigabit Ethernet Switch

The Extreme Networks 16535A is a managed Gigabit Ethernet switch that supplies forty-eight RJ-45 ports, each capable of delivering full IEEE 802.3at PoE plus power. It is built for organisations that want to simplify cabling, keep edge devices powered, and maintain reliable connectivity without constant hands-on attention.

Every port can provide up to thirty watts from a shared 740-watt budget, so you can run wireless access points, VoIP phones, security cameras, or building-automation sensors directly from the switch. Eight dedicated SFP slots let you choose fibre or copper uplinks, and they support optional 10 Gigabit modules when higher bandwidth is required.

The switch runs the proven ExtremeXOS operating system, giving network teams a consistent interface, extensive Layer 2 and Layer 3 features, and role-based policy controls that help segment traffic and enforce security without extra hardware. If you need more ports down the road, you can stack up to eight X440-G2 units and manage them as one logical device, which keeps administration straightforward while preserving valuable rack space.

This model fits in a standard rack with a one rack-unit height, making it an easy drop-in for wiring closets, branch offices, classrooms, or retail spaces that are expanding their IP infrastructure. With continuous uptime features and manageable power consumption of up to 961 watts at full load, it supports day-to-day operations while leaving room for network growth.
