Altronix NETWAYSP4BTWP3 4-Port PoE++ 360W

Altronix NETWAYSP4BTWP3 Hardened 4-Port PoE++ Managed Network Switch

Overview

The Altronix NETWAYSP4BTWP3 is a ruggedized, IP66-rated managed network switch engineered for outdoor surveillance, access control, and networked security deployments requiring IEEE 802.3bt Power over Ethernet (PoE++) support. This unit combines a 4-port hardened Gigabit Ethernet switch with integrated 360W power supply and charger functionality, all housed in a NEMA 4/4X stainless steel enclosure. The NETWAYSP4BTWP3 is designed to deliver reliable network connectivity and high-power delivery in harsh environmental conditions where standard commercial-grade equipment cannot operate.

Key Features

• 4-Port Gigabit Ethernet Switch: Full-duplex 1Gbps network connectivity on all ports with managed switching capabilities for network segmentation and traffic control
• 802.3bt PoE++ Support: Delivers up to 90W per port via Power over Ethernet, supporting high-power networked cameras, access controllers, and integrated IoT endpoints without separate power infrastructure
• 360W Integrated Power Budget: Sufficient capacity to power four maximum-load PoE++ devices simultaneously, with integrated power supply rated for 230VAC input
• Dual Fiber Optic SFP 1G Link: Integrated dual SFP (Small Form-factor Pluggable) slots support single-mode and multimode fiber connections, enabling isolation from ground loops and long-distance backbone connectivity without electromagnetic interference
• NEMA 4/4X IP66 Outdoor Enclosure: Stainless steel construction rated for complete dust ingress protection and powerful water jets, certified for outdoor wall or pole mounting in demanding environments
• Managed Network Features: VLAN support, quality of service (QoS) controls, and port configuration management enable fine-grained network policy implementation for multi-tenant or security-zoned deployments
• Integrated Charger Function: Built-in charging capability supports battery backup systems, enabling UPS integration for continuity during AC mains failure
• Industrial-Grade Reliability: Designed for 24/7 operation in outdoor mounting scenarios with passive thermal management suitable for wide temperature ranges

Integration & Compatibility

The NETWAYSP4BTWP3 operates as a standalone managed switch compatible with any standard IP security camera, network access controller, or Ethernet-enabled networked device supporting IEEE 802.3bt power delivery. The dual SFP fiber ports allow backbone connectivity to distant head-end equipment or ring-topology redundancy without adding copper cable runs subject to EMI or lightning risk. The managed switch interface supports integration with standard network monitoring and configuration tools, enabling remote management of port status, power allocation, and network diagnostics. The unit's 230VAC input voltage accommodates both North American and international power standards, with integrated AC-to-DC conversion and battery charging support for hybrid AC/DC deployments.

Power and Electrical Specifications

Input voltage is 230VAC. The unit provides a maximum power budget of 360W distributed across four PoE++ ports, each capable of 90W delivery per IEEE 802.3bt specifications. The integrated power supply includes charger functionality for battery backup applications, enabling graceful shutdown or continued operation during AC mains loss. All power delivery is managed through integrated protection and switching circuits designed for outdoor industrial use.

Jerry Tildsen

During a recent multi-camera outdoor security deployment, I evaluated the Altronix NETWAYSP4BTWP3 as a replacement for distributed AC power drops and separate PoE injectors. This managed switch consolidated network delivery and power distribution at the edge, eliminating conduit runs and reducing installation labor significantly. The NEMA 4X enclosure and IP66 rating proved essential in a wet coastal environment where standard commercial switches failed within months.

Technical Highlights:

• PoE++ Power Delivery: The 360W budget and per-port 90W capacity handled our mix of PTZ cameras (90W) and fixed 4K units (60W) without oversubscription, allowing four simultaneous high-power devices on a single compact unit
• Fiber Backbone Integration: The dual SFP 1G fiber ports enabled trunk connections to our central switch without copper EMI concerns, critical in an RF-dense environment with cellular towers nearby
• Managed Switching: VLAN and QoS controls allowed us to isolate camera traffic from access control networks, improving predictability and security posture across the deployment

Deployment Considerations:

• The 230VAC input requires confirmation of local power availability; if only 120VAC is present on-site, a step-up transformer is necessary, adding cost and footprint to the installation
• Plan fiber connectivity during design phase—the dual SFP slots unlock the unit's backbone capability, but fiber termination and testing must occur before final deployment
• The integrated charger function requires pairing with external battery packs (sold separately); calculate backup duration based on actual PoE load to ensure adequate UPS capacity

The NETWAYSP4BTWP3 is a solid choice for outdoor surveillance and access control integrations where power and network consolidation reduce TCO and improve reliability. The managed switching and fiber support position it for scalable multi-site deployments with professional-grade operational oversight.
