Altronix NETWAY4EBTB 4-Port Gigabit PoE Switch

Altronix NETWAY4EBTB 4-Port Gigabit PoE Switch Board

Overview

The Altronix NETWAY4EBTB is a hardened switch board designed for security and access control system integrators requiring high-density Power over Ethernet delivery in bandwidth-constrained or fiber-optic network environments. This 4-port switch delivers full gigabit Ethernet performance with single-mode fiber optic SFP connectivity and advanced 802.3bt power delivery specifications. The NETWAY4EBTB operates from 48–56V DC input and is purpose-built for direct integration into cabinet systems, PDU frames, and distributed network architectures where space and power efficiency are critical.

Key Features

• Four 10/100/1000 Gigabit Ethernet Ports: Full-duplex switching with automatic speed negotiation and auto MDI/MDIX crossover detection
• Single 1G Fiber Optic SFP Uplink: Single-mode fiber connectivity for extended distance network backbone integration and EMI isolation
• 802.3bt 4PPoE Support: Four independent power delivery paths, each rated for 90W maximum per port with 240W total power budget
• 48–56V DC Input Requirement: Direct integration with standard cabinet power supplies and redundant PSU architectures
• Hardened Design: Industrial-grade component selection and conformal coating for reliability in non-climate-controlled environments
• Switch Board Form Factor: Compact board-only design for OEM integration, cabinet mounting, and custom enclosure deployment
• LINQ Ecosystem Integration: Compatible with Altronix LINQ power management and supervision framework for centralized monitoring and control

Integration & Compatibility

The NETWAY4EBTB integrates seamlessly into Altronix LINQ-enabled cabinets and multi-unit power architectures. The board accepts 48–56V DC input, matching standard Altronix redundant power supply outputs and distributed cabinet configurations. Four Gigabit copper ports provide direct connection to IP cameras, access control readers, intercoms, and edge IoT devices; the fiber SFP uplink enables long-distance, noise-immune network segmentation and backbone connectivity. When deployed with compatible Altronix power supplies and management modules, the NETWAY4EBTB provides supervision, remote reboot, and load-shedding capability across the entire PoE infrastructure.

Typical Applications

System integrators deploy the NETWAY4EBTB in camera systems, multi-door access control networks, intercom and emergency communication deployments, and distributed building security architectures where localized fiber routing and high-density PoE consolidation are required. The fiber SFP option eliminates ground loops and EMI in mixed analog and digital environments. The 240W total power budget supports up to four midspan or endpoint devices rated up to 90W each, including 4K IP cameras, PTZ systems, and powered access control hubs.
