X435-24P-4S: High-Performance PoE+ Switch for Distributed Enterprises

The Extreme Networks X435-24P-4S is a 24-port Gigabit Ethernet switch designed for branch offices, small sites, and edge deployments. It delivers robust Power over Ethernet (PoE+) support, advanced Layer 2 features, and cloud-ready management capabilities. Ideal for powering IP phones, wireless access points, and IoT devices, this switch offers a cost-effective and scalable networking solution.

Key Features:

• 24 x Gigabit Ethernet PoE+ ports (30W per port)
• 4 x 1G/2.5G SFP uplink slots
• 370W total PoE budget
• Cloud management via ExtremeCloud™ IQ
• Fabric Attach for automated service provisioning
• Fanless operation (8-port models); quiet fans (24-port models)

Characteristics

• High-density PoE+ support for edge devices
• Flexible uplink options with 2.5Gb capability
• Zero-touch provisioning and cloud management
• Advanced security and role-based policy enforcement
• Audio Video Bridging (AVB) for real-time multimedia

Technology

The X435-24P-4S runs on ExtremeXOS®, a robust operating system supporting Layer 2 switching, static routing, and advanced PoE features like perpetual PoE and Fast PoE. It complies with IEEE standards including 802.3at (PoE+), 802.3bt, 802.1AVB, and 802.3az Energy Efficient Ethernet.

Working Principle

The switch operates at the network edge, aggregating traffic from end devices and forwarding it via high-speed uplinks. It supports PoE power sourcing from an upstream switch or internal PSU, and can be managed centrally through ExtremeCloud IQ for unified policy and visibility across wired and wireless networks.

Application

Ideal for:

• Branch offices and remote sites
• Schools and healthcare facilities
• Retail and hospitality environments
• IoT and surveillance camera deployments
• Unified communications and AV streaming
