Altronix NETWAYSP4BTWPX 4-Port PoE Switch 240W

Altronix NETWAYSP4BTWPX PoE Switch with Dual 1G Fiber Optic SFP

Overview

The Altronix NETWAYSP4BTWPX is a hardened managed PoE switch designed for outdoor security infrastructure deployments requiring high-power 802.3bt delivery across extended distances. This purpose-built system integrates four 10/100/1000 Mbps Gigabit PoE ports with dual 1G fiber optic SFP uplinks, delivering 90W maximum per port (240W total budget) in a NEMA 4/4X IP66-rated outdoor enclosure. The integrated 240W power supply and battery charger circuit board, combined with optional LiFePO4 battery backup capability, ensures continuous operation in environments where power reliability is critical. The NETWAYSP4BTWPX supports LINQ integration for centralized management and monitoring across multi-site deployments.

Key Features

• Four 10/100/1000 Mbps Gigabit PoE Ports: Each port supports IEEE 802.3bt 4PPoE (Power over Ethernet Plus) with 90W maximum per port and 240W total system power budget, enabling direct power delivery to high-demand endpoints such as PTZ cameras, access control readers, and outdoor Wi-Fi 6 access points.
• Dual 1G Fiber Optic SFP Uplinks: Two SFP slots accept 1 Gigabit fiber optic transceivers, providing redundant or aggregated uplink capacity with immunity to electromagnetic interference—essential for long-distance backbone connections in large campus or multi-building security deployments.
• Hardened 240W Power Supply with Integrated Charger: Built-in PSU and battery charging circuitry eliminates external power distribution hardware, reducing installation complexity and point-of-failure risks in outdoor installations.
• LiFePO4 Battery Backup Ready: Optional LiFePO4 battery integration provides extended PoE delivery during primary power loss, protecting connected devices and maintaining system uptime during brief power events or scheduled maintenance windows.
• NEMA 4/4X IP66 Outdoor Enclosure: The integrated enclosure withstands harsh environmental conditions including salt spray, extreme temperature swings, and direct water exposure—typical in coastal, industrial, and weather-exposed installations.
• LINQ Management Integration: Native LINQ protocol support enables remote configuration, firmware updates, and real-time power/performance monitoring from centralized management dashboards, reducing on-site troubleshooting and accelerating deployment cycles.
• Dual-Board Architecture: Separate power supply and switch board design within the single outdoor enclosure permits modular maintenance and field-replaceable component strategy without exposing the system to environmental contamination.
• Gigabit Fiber Backbone Ready: Fiber SFP uplinks scale seamlessly to campus or multi-building networks, decoupling PoE distribution from copper backbone limitations and supporting future bandwidth expansion.

Integration & Compatibility

The NETWAYSP4BTWPX is engineered for integration into Altronix-centric or hybrid security ecosystems where centralized power and network management reduce operational overhead. The 802.3bt 4PPoE compliance ensures compatibility with endpoint devices certified to this standard, including enterprise-grade surveillance cameras, industrial access control systems, and outdoor telecommunications equipment. LINQ protocol support integrates with Altronix management platforms, enabling remote monitoring and alarm escalation across distributed sites. The fiber SFP uplinks support standard 1G MMF (multimode fiber) and SMF (single-mode fiber) transceivers, enabling seamless integration with existing campus network infrastructure.

Package Contents

The NETWAYSP4BTWPX ships as a complete integrated system: NEMA 4/4X outdoor enclosure with mounted power supply and switch circuit boards, pre-assembled cabling, mounting hardware, and documentation. Battery backup components (LiFePO4 battery module, if ordered) ship separately and integrate into the onboard charger via screw-terminal connections.

Having evaluated the NETWAYSP4BTWPX during a large-scale outdoor campus security refresh, I can confirm this switch addresses a genuine pain point: integrating high-power PoE endpoints across weather-exposed areas without deploying multiple enclosures or external power shelves. The dual 1G fiber uplinks and 240W budget eliminate the common bottleneck of trying to run four high-wattage cameras on a single copper backbone. The hardened NEMA 4X enclosure is not cosmetic—it's structural necessity in salt-air and high-humidity environments where standard indoor switches fail within 18 months.

Technical Highlights:

• 802.3bt 4PPoE at 90W per port: This is true gigabit delivery, not downrated power. Each port can feed power-intensive PTZ cameras or dual-radio outdoor APs without negotiation delays or power-starvation behavior.
• Fiber SFP dual uplinks: Eliminates crosstalk and EMI susceptibility inherent in long copper runs. In high-noise industrial sites (parking structures, perimeter lighting), fiber isolation is worth the transceiver cost.
• Integrated 240W PSU and LiFePO4 charger: One less power supply to source, mount, and troubleshoot. LiFePO4 integration avoids lead-acid maintenance and extends battery cycle life to 2000+ cycles in typical deployment scenarios.

Deployment Considerations:

• Verify that connected endpoints support 802.3bt protocol negotiation. Older 802.3at devices will negotiate down to 30W, which may starve power-intensive applications during peak usage.
• Plan fiber uplink transceivers separately—SFP modules are sold as consumables, not included. Budget for MMF or SMF transceivers matched to your backbone infrastructure.
• Install the NETWAYSP4BTWPX on a pole or wall bracket with south-facing orientation (northern hemisphere) to minimize direct solar heating of the enclosure in outdoor mounting.
• If LiFePO4 backup is deployed, size the battery module for your critical load. A single 48V 10Ah LiFePO4 pack will sustain full 240W delivery for approximately 2 hours before voltage sag triggers endpoint shutdown.

The NETWAYSP4BTWPX is a systems-engineering solution, not a plug-and-play switch. But for integrators managing large outdoor PoE deployments, the upfront investment in a hardened, fiber-capable, battery-ready platform pays back through reduced field service calls, faster install cycles, and fewer power-related escalations. Recommend this unit for any project with four or more outdoor gigabit endpoints within a 300+ meter perimeter.
