Extreme Networks X435-8P-4S: Advanced 8-Port PoE+ Cloud-Managed Switch

1. Product Overview

The Extreme X435-8P-4S represents the next generation of compact networking switches, delivering enterprise-grade features in a space-efficient design. This 8-port Gigabit Ethernet switch combines robust Power over Ethernet Plus (PoE+) capability with flexible 2.5GbE uplink options, making it an ideal solution for modern distributed networks. Engineered for reliability and performance, this switch provides seamless connectivity for bandwidth-intensive applications while supporting power delivery to connected devices.

2. Key Characteristics

• 8 x Gigabit Ethernet ports with IEEE 802.3at PoE+ support (30W per port)
• 4 x 1G/2.5GBASE-X SFP uplink ports for high-speed connectivity
• Total PoE budget of 124W for powering multiple devices simultaneously
• Fanless design ensures completely silent operation
• Cloud management capability through ExtremeCloud™ IQ platform
• Layer 2 switching with advanced security features
• Fabric Attach technology for automated network provisioning

3. Core Technology

The X435-8P-4S leverages Extreme's proven ExtremeXOS operating system, delivering enterprise-class networking features including:

• IEEE 802.3at PoE+ for powered device connectivity
• IEEE 802.3bz (2.5GBASE-T) compatibility on uplink ports
• IEEE 802.1 Audio Video Bridging (AVB) for multimedia applications
• Role-based network access control through ExtremeControl
• Automated Fabric Attach connectivity
• Energy Efficient Ethernet (IEEE 802.3az)

4. Operational Principle

This switch operates as a intelligent network distribution point, providing both data connectivity and power delivery over standard Ethernet cabling. The integrated PoE+ functionality eliminates the need for separate power supplies for connected devices. The four SFP uplink ports enable high-speed backbone connections using either fiber or copper transceivers. Management can be performed locally through web interface or command line, or centrally through the ExtremeCloud IQ cloud management platform.

5. Application Scenarios

• Small and medium business network infrastructure
• Branch office and remote site connectivity
• IP surveillance system deployment
• Wireless access point connectivity and power delivery
• VoIP phone system implementation
• Digital signage and multimedia streaming networks
