Altronix NETWAYSP41BTWP 4-Port Hardened Managed Fiber Switch with PoE+
Overview
The Altronix NETWAYSP41BTWP is a ruggedized 4-port managed Ethernet switch purpose-built for remote outdoor deployments requiring high-powered PoE capability and extended fiber connectivity. This hardened switch combines four 802.3bt-compliant Gigabit Ethernet ports with two 1Gb SFP fiber ports, delivering 90W per port (240W total) to support the latest generation of high-demand IP security devices, access control systems, and remote communications equipment in challenging environments.
Engineered for field deployment, the NETWAYSP41BTWP board integrates AC/DC power conversion (115VAC 60Hz or 230VAC 50/60Hz input), onboard battery charging capability, and integrated surge protection—eliminating the need for separate ancillary components in typical security system architectures.

Integration & Deployment Considerations
The NETWAYSP41BTWP is designed for integration into NEMA 4/4X, IP66-rated outdoor enclosures where it functions as both a managed switching fabric and integrated power supply/charger. Its dual SFP fiber ports enable long-distance connectivity from centralized head-end equipment, while its four PoE+ ports support simultaneous deployment of four high-power IP cameras, access readers, emergency communication endpoints, or other 802.3bt-class devices at remote sites.
The integrated 24VDC battery charging circuit accepts LiFePO4, sealed lead acid, or gel batteries (up to four 12VDC/4AH units in typical configurations) to enable uninterrupted operation during AC power loss. LED status indicators provide real-time visibility into PoE delivery, link integrity, fiber connectivity, and device health—critical for field troubleshooting and maintenance planning.
Temperature derating applies based on total power draw: systems operating at 240W maximum power are rated to -40°C to 55°C, while lower-load deployments achieve higher temperature ceilings. This specification allows integrators to plan installations in desert, arctic, and coastal environments without thermal re-rating.

I've specified the Altronix NETWAYSP41BTWP in several remote critical infrastructure deployments over the past two years. This is a genuinely purpose-built device that solves a real problem: combining managed switching, high-power PoE delivery, fiber long-haul connectivity, and integrated battery charging in a single board-only module significantly reduces BOM complexity and system footprint compared to stacking discrete components.
Technical Highlights:
- Per-Port Power Delivery: The 90W per-port 802.3bt compliance is a material differentiator. You can deploy four full-power PTZ cameras, four high-draw access readers, or mixed workloads without port-to-port load-sharing concerns. The 240W total budget is honest engineering—no marketing inflating headline watts.
- Fiber Ports as Standard: Dual SFP Gigabit ports eliminate the need for external media converters in most remote deployments. Multi-mode and single-mode support means you're not locked into one fiber strategy. I've used this in 2km+ runs from a central NOC.
- Battery Integration: The 24VDC charging circuit is a practical touch. Customers typically mount this board in a NEMA 4X box with four 12V/4Ah LiFePO4 cells in series for 48V nominal, or parallel pairs for 12V high-capacity backup. Instantaneous failover timing is good—no power blink to IP devices.
Deployment Considerations:
- This is a board-only product. You must specify an appropriate outdoor enclosure (NEMA 4/4X minimum for security work) and handle thermal management planning. At 122 BTU/Hr, passive convection works in most climates, but confirm temperature derating against your worst-case power load scenario before order.
- LED indicators are your troubleshooting lifeline in the field. Familiarize your team with the heartbeat, link status, and PoE On indicators before deployment. A non-functional ALOS LED, for example, tells you the SFP fiber interface is down—critical diagnostic data without a serial console.
- Verify battery chemistry compatibility before installation. LiFePO4 batteries deliver better cycle life and temperature stability than sealed lead acid in remote outdoor sites. Budget for a properly ventilated battery enclosure if you're using lead-acid cells.
The NETWAYSP41BTWP is genuinely reliable infrastructure-grade switching with realistic power budgets and practical fiber support. If you're building a remote PoE+ system with fiber backbone requirements, this board earns serious consideration.
