Altronix NETWAYSP4BTWP 4-Port 802.3bt PoE Switch

Altronix NETWAYSP4BTWP 4-Port 802.3bt PoE Switch with Fiber Uplink

Overview

The Altronix NETWAYSP4BTWP is a ruggedized managed PoE switch designed for outdoor security and IP device deployments requiring extended power delivery and fiber-optic network isolation. This industrial-grade unit combines four 10/100/1000 Mbps Ethernet ports with dual 1G fiber optic SFP uplinks, delivering up to 90W per port (240W aggregate budget) over Cat5e/Cat6 copper runs. The NETWAYSP4BTWP is housed in a NEMA 4/4X, IP66-rated enclosure and includes a hardened 240W power supply paired with integrated SLA or LiFePO4 battery charger support, making it suitable for mission-critical outdoor installations where power redundancy and environmental protection are mandatory.

Key Features

• Four 802.3bt High-Power PoE Ports: Delivers up to 90W per port, supporting next-generation high-current devices including pan-tilt-zoom cameras, access control readers, and advanced lighting systems. Maximum aggregate PoE budget of 240W ensures simultaneous maximum-power delivery across all ports.
• Dual 1G Fiber Optic SFP Uplinks: Provides electrical isolation and extended reach for network backbone connectivity; eliminates ground loops and extends distances beyond copper limitations in noisy or distributed outdoor environments.
• 240W Hardened Power Supply: Industrial-rated supply with wide input voltage tolerance and surge protection suitable for outdoor and remote deployment scenarios.
• Integrated Battery Charger: Built-in charging support for SLA (sealed lead-acid) or LiFePO4 battery backup modules, enabling uninterrupted PoE delivery during utility power loss or brownout conditions.
• NEMA 4/4X IP66 Enclosure: Fully sealed, corrosion-resistant outdoor-rated enclosure protects all switch boards and power components from rain, dust, salt spray, and environmental contaminants. Suitable for rooftop, pole, and ground-level installations.
• LINQ Integration Platform: Integrates with Altronix LINQ centralized power and device management ecosystem for remote monitoring, firmware updates, and multi-unit supervision across distributed security deployments.
• Gigabit Copper Port Capacity: All four ports support 10/100/1000 Mbps, accommodating both legacy and current-generation network equipment without bottlenecking throughput.
• Switch Board Architecture: Modular internal structure with separate power and network switch boards mounted within the enclosure, enabling field serviceability and component-level diagnostics.

Integration & Compatibility

The NETWAYSP4BTWP operates as a managed Ethernet switch compatible with standard 802.3bt Power over Ethernet endpoints and legacy 802.3at/af devices. The dual SFP uplinks accept industry-standard 1G fiber transceivers, allowing integration into existing fiber backbone networks. Support for both SLA and LiFePO4 charger configurations provides flexibility across different battery backup architectures. LINQ compatibility enables centralized monitoring and control within larger Altronix power distribution systems, streamlining multi-site installations.

Typical Deployment Scenarios

Ideal for outdoor perimeter security deployments, roof-mounted camera clusters, distributed access control networks, and remote communication tower sites where four high-power PoE devices must operate reliably under environmental stress. The combination of fiber uplinks and sealed enclosure makes the NETWAYSP4BTWP particularly valuable in electrical noise-prone environments, coastal installations, or scenarios requiring galvanic isolation between network segments.

Jerry Tildsen

During a recent large-scale outdoor camera deployment in a high-interference environment, I evaluated the Altronix NETWAYSP4BTWP as a candidate for our fiber-fed network architecture. The unit's combination of four simultaneous 90W PoE outputs and dual 1G SFP uplinks proved essential for our topology—we needed both electrical isolation via fiber and enough local PoE capacity to support PTZ cameras and auxiliary lighting on a single outdoor cabinet.

Technical Highlights:

• 90W per-port PoE delivery: The 802.3bt rating ensures modern high-draw devices operate at full capability without voltage sag, and the 240W aggregate budget allows all four ports to deliver maximum power simultaneously without overload management complexity.
• Dual 1G SFP fiber uplinks: Eliminates ground loop noise that plagued earlier copper-only designs; the SFP form factor allows field swaps of transceiver modules to match existing fiber inventory (multimode, single-mode, wavelength-specific).
• Battery charger integration: The built-in SLA/LiFePO4 charger simplifies cabinet design—no separate charger module required; supports both older SLA chemistries and modern LiFePO4 for sites upgrading to longer-life backup batteries.

Deployment Considerations:

• The NEMA 4/4X IP66 enclosure is critical for outdoor roof mounting; confirm proper cable gland sealing and grounding to maintain environmental rating over the system lifetime.
• Verify fiber transceiver compatibility before deployment; SFP modules must match your backbone infrastructure (multimode vs. single-mode, wavelength), and spares should be stocked for quick field replacement.
• For battery backup scenarios, size the connected battery bank based on the PoE load profile and desired runtime; LiFePO4 modules offer superior cycle life and safer thermal characteristics than SLA in high-cycling applications.

The NETWAYSP4BTWP is a solid choice for integrators building resilient outdoor PoE networks where environmental sealing, fiber isolation, and high simultaneous power delivery are non-negotiable. The LINQ integration adds valuable remote diagnostics capability for distributed multi-cabinet projects.
