Altronix NETWAYSP4BTWPX3 Hardened Managed Network Switch with 360W Power Supply
Overview
The Altronix NETWAYSP4BTWPX3 is a field-hardened, managed Ethernet switch purpose-built for outdoor security and critical infrastructure deployments. This integrated solution combines a 4-port 802.3bt High Power over Ethernet (PoE) switch with a 360W internal power supply and charger, housed in a NEMA 4/4X, IP66-rated enclosure rated for harsh environmental conditions. The NETWAYSP4BTWPX3 supports dual fiber optic SFP ports for 1G uplinks, enabling long-distance backbone connectivity while maintaining galvanic isolation. Accommodating up to four (4) 12VDC/4AH batteries, this unit provides extended runtime during primary power loss, making it suitable for continuous-duty surveillance, access control, and telemetry applications where power redundancy is critical.
Key Features
- 802.3bt High Power PoE: Four copper ports deliver up to 90W per port per IEEE 802.3bt standard, supporting power-hungry devices such as PTZ cameras, thermal imagers, and edge-mounted servers without auxiliary power drops.
- 360W Internal Power Supply: Rated 360W with integrated charger function, capable of simultaneously powering PoE outputs and charging battery backup modules.
- Dual 1G Fiber SFP Uplinks: Two fiber optic Small Form-factor Pluggable ports provide redundant 1 Gigabit backbone connections with immunity to electromagnetic interference, critical for long-distance runs and environments with high EMI.
- NEMA 4/4X IP66 Outdoor Enclosure: Sealed powder-coated steel enclosure rated for direct outdoor mounting; meets NEMA 4 and 4X environmental specifications and IP66 dust and water ingress protection.
- Battery Backup Capacity: Supports four (4) 12VDC/4AH batteries (48Ah total), enabling extended runtime for critical network segments during power loss.
- Managed Switch Fabric: Full Layer 2/3 management capabilities including VLAN tagging, spanning tree, SNMP monitoring, and LLDP discovery for network visibility and segmentation in complex installations.
- Wide Operating Temperature: Engineered for deployment across North American climates and temperature extremes common in outdoor surveillance and infrastructure monitoring.
- Hot-Swap Battery Module: Designed to accept hot-swappable battery cartridges without powering down network services.
Integration & Compatibility
The NETWAYSP4BTWPX3 integrates seamlessly into hybrid fiber/copper network architectures. The dual SFP ports support standard LC connectors with single-mode or multi-mode fiber modules (sold separately), enabling backbone connectivity to distant head-end equipment. The four copper PoE ports are backward-compatible with 802.3af/at devices while supporting full 802.3bt power delivery for next-generation devices. Managed switch features include SNMP v2/v3 for integration with NOC monitoring platforms, static routing, and QoS tagging for bandwidth prioritization of video and access control traffic. The integrated charger automatically maintains battery state-of-charge under float conditions, reducing operational overhead in unattended remote locations.

During recent deployment planning for a regional surveillance backbone, I evaluated the Altronix NETWAYSP4BTWPX3 as the core distribution node for a multi-site fiber-linked network. The combination of 802.3bt PoE capacity with onboard battery redundancy and fiber uplinks addresses a genuine gap in outdoor switch offerings: the need for power autonomy without external UPS complexity.
Technical Highlights:
- 360W Power Budget with Charger: The integrated power supply eliminates the need for separate AC-UPS or external chargers in remote cabinets. Running four 90W PoE ports plus battery charging is uncommon in field-hardened designs.
- Dual Fiber SFP: Two independent fiber ports enable true redundancy—primary and backup backbone connections with full galvanic isolation from copper network segments, reducing ground loop issues in installations with mixed infrastructure.
- Battery Autonomy: Four 12VDC/4AH slots (48Ah total) provide realistic runtime for critical segments during extended outages. Sizing depends on load, but a four-camera PoE draw typically yields 4–6 hours of operation.
Deployment Considerations:
- Verify your fiber SFP transceiver type (single-mode vs. multi-mode) before installation; SFPs are NOT included and must match your backbone infrastructure.
- In high-humidity coastal or industrial environments, plan quarterly enclosure drain plug maintenance to prevent condensation accumulation inside the IP66 housing.
- The managed switch feature set (VLAN, SNMP, QoS) requires initial configuration; do not rely on plug-and-play default settings for production networks requiring bandwidth isolation or traffic shaping.
The NETWAYSP4BTWPX3 is a solid choice for integrators building resilient outdoor networks where commercial power is unreliable and fiber backbone connectivity is non-negotiable. The 360W supply and battery bay eliminate single points of failure that plague cheaper consumer-grade switches. Plan your SFP inventory carefully and budget time for managed switch configuration.
