Altronix NETWAYSP4BTPL 4-Port 802.3bt PoE Switch

Altronix NETWAYSP4BTPL PoE Switch with Fiber Uplink

The Altronix NETWAYSP4BTPL is a hardened managed PoE switch designed for security infrastructure deployments requiring high power delivery and redundant connectivity. This 4-port gigabit ethernet switch delivers up to 90W per port (240W aggregate) over 802.3bt high-power PoE, making it suitable for powering multiple professional surveillance cameras, access control readers, and networked sensors simultaneously. The dual 1G fiber optic SFP uplink ports provide backbone connectivity with immunity to EMI and support for extended cable runs in challenging RF environments common to large-scale integrations.

Key Features

• Four 10/100/1000 Mbps Copper Ports: Full-duplex gigabit ethernet connectivity with automatic speed negotiation for mixed-speed device compatibility
• 802.3bt High-Power PoE: Delivers up to 90W per port with 240W total system power budget for demanding powered devices
• Dual 1G Fiber SFP Uplinks: Two SFP slots accept standard 1 Gigabit SFP transceivers for redundant backbone connections and extended-distance runs up to 10 km with appropriate optics
• Hardened 240W Power Supply: Integrated power supply rated for continuous operation in industrial environments
• Optimized Battery Charger & Backup: Onboard charger compatible with both sealed lead-acid (SLA) and LiFePO4 battery modules for seamless UPS integration and emergency backup runtime
• Metal Backplane Mounting: Industrial-grade chassis with integrated DIN rail compatibility for secure cabinet installation
• LINQ Integration Ready: Supports Altronix LINQ software platform for centralized power distribution and PoE device management

Integration & Compatibility

The NETWAYSP4BTPL switch integrates directly into Altronix power and access control ecosystems via LINQ monitoring and control. The combination of hardened power supply and onboard battery charger eliminates the need for separate UPS hardware in many deployments, reducing cabinet footprint and simplifying system architecture. Four ports deliver sufficient PoE capacity for mid-sized camera networks, edge access control arrays, or mixed surveillance and IoT sensor installations. The fiber uplinks decouple the switch from copper cable distance limitations and electrical noise, critical for long-run backbone connections in sprawling campuses or multi-building properties.

Power Management & Redundancy

The integrated 240W power supply and battery charger board handle both AC mains charging and backup power conditioning. Support for SLA and LiFePO4 chemistries provides flexibility in backup capacity selection—LiFePO4 extends cycle life and reduces maintenance compared to lead-acid alternatives. The metal backplane ensures proper heat dissipation and mechanical rigidity for continuous operation in non-climate-controlled enclosures.

During integration planning for a multi-building access control retrofit, the Altronix NETWAYSP4BTPL proved essential for consolidating camera and reader power into a single managed distribution point. The model delivers the per-port wattage needed for high-resolution PTZ cameras and dual-card readers without external PoE injectors, and the fiber uplinks keep our backbone isolated from the RF noise generated by access control systems running parallel to network cabling.

Technical Highlights:

• High Per-Port Budget: 90W per port enables single-cable power for professional surveillance and reader installations without cascaded injectors
• Fiber Backbone: Dual 1G SFP slots support redundant uplinks and eliminate distance and EMI constraints on system backbone
• Integrated Battery Charger: Onboard charger and LiFePO4 support reduce cabinet complexity and power loss through external UPS conversion

Deployment Considerations:

• Confirm SFP transceiver compatibility and fiber grade (singlemode vs. multimode) before installation; standard 1G SFPs are widely supported but verify with your backbone equipment
• Plan backup battery capacity based on PoE device runtime requirements; 90W per port at full load requires substantial battery for meaningful UPS duration

For integrators managing mid-to-large IP security estates, the NETWAYSP4BTPL eliminates multiple single-function components and delivers fiber-backed resilience in a compact form factor. The native LINQ support integrates seamlessly into Altronix environments.
