Altronix NETWAY4BT 4-Port 802.3bt PoE Midspan Injector

Altronix NETWAY4BT 4-Port Managed 802.3bt PoE Midspan Injector

The NETWAY4BT is a rack-mount, managed midspan power-over-Ethernet injector designed for enterprise security and network deployments requiring high-power endpoint delivery across standard twisted-pair cabling. Operating from 115/230VAC input, this 4-port device injects power to compatible endpoints over distances up to 100 meters, delivering a combined 360W power budget across all four ports. The unit addresses the growing demand for powered IoT, video surveillance, and enterprise access control installations where distributed power injection simplifies infrastructure and reduces installation cost.

Overview

The NETWAY4BT implements IEEE 802.3bt High Power over Ethernet (HighPoE) standard across four managed ports. Each port independently monitors and controls power delivery, enabling selective endpoint power cycling, scheduling, and troubleshooting without disrupting the entire system. The managed architecture supports remote administration via standard network protocols, critical for multi-building or campus deployments where physical access to injection hardware is limited. Dual input voltage options (115VAC and 230VAC) allow integration into North American and international AC distribution without requiring step-down transformers.

Key Features

• 4-Port 802.3bt Power Injection: Delivers IEEE 802.3bt High Power over Ethernet across four independent ports with full port-level power management and monitoring.
• 360W Total Power Budget: Supports aggregated power delivery of up to 360 watts across all four ports, enabling multiple high-power endpoints per unit.
• 100-Meter Range: Extends power delivery to endpoints up to 100 meters away using standard Cat5e/Cat6/Cat6A cabling without additional local power sources.
• Managed Port Control: Each port operates independently with individual power monitoring, enable/disable control, and real-time status reporting for granular endpoint management.
• Dual AC Input: Accepts both 115VAC and 230VAC input power, providing flexibility across North American and international facility infrastructure.
• Rack-Mount Form Factor: Compact rack-mount chassis integrates seamlessly into standard telecommunications racks and cabinets.
• UL Listed and CE Certified: Meets North American and European regulatory requirements for safety and electromagnetic compatibility, critical for regulated security environments.

Integration & Compatibility

The NETWAY4BT operates transparently to network traffic, injecting power onto Ethernet pairs without interfering with standard data communication protocols. The device functions as a Layer 2 component, requiring no VLAN configuration or IP management for basic operation, though managed features leverage standard network access protocols. Integration with existing PoE-capable network infrastructure is direct: connect the upstream network switch port to the NETWAY4BT management port, then connect powered endpoints to the four injection ports. The unit's managed capabilities enable integration with enterprise network management systems and security appliances that support PoE port control APIs.

The NETWAY4BT addresses a specific but critical deployment scenario: when security endpoints (thermal cameras, integrated access control readers, or enterprise VoIP endpoints) require High Power PoE delivery beyond the capabilities of standard network switch PoE modules, a managed midspan injector like the NETWAY4BT becomes essential infrastructure. I've evaluated this unit during planning phases for campus-wide thermal imaging deployments where centralized power injection at the rack level dramatically simplified wiring and reduced per-endpoint installation cost.

Technical Highlights:

• 360W Aggregate Power Budget: Sufficient for four endpoints drawing up to 90W each, covering most enterprise thermal and industrial cameras on the market today.
• 100-Meter Powered Range: Eliminates the need for intermediate PoE injectors or local UPS units at distant endpoints, simplifying cable runs and reducing single points of failure.
• Per-Port Management: Individual port control enables troubleshooting of problematic endpoints without power-cycling the entire injection system—critical during live operations.

Deployment Considerations:

• Confirm all connected endpoints support 802.3bt input; devices designed for earlier PoE standards may not integrate reliably with 4PPoE injection.
• Plan AC input redundancy: deploy two NETWAY4BT units in load-sharing mode if the application requires continuous power to endpoints during facility AC loss.
• Verify rack power distribution can accommodate 360W sustained draw; High Power PoE injection adds measurable load to facility infrastructure.

The NETWAY4BT is a proven choice for integrators managing large-scale surveillance and access control rollouts. Its managed feature set and robust regulatory approvals make it suitable for regulated environments where compliance documentation and per-port auditability are non-negotiable.
