Altronix NETWAYSP4BTX3 4-Port Hardened Managed 802.3bt PoE Switch with Dual SFP and 360W Power Supply

Overview

The Altronix NETWAYSP4BTX3 is a hardened, managed 802.3bt PoE switch and integrated 360W power supply housed in a NEMA1-rated indoor enclosure — built for security integrators who need to push high-power IP devices (pan-tilt-zoom cameras, multi-sensor heads, access control panels) to remote locations over fiber without a separate power supply in the cabinet. Four PoE ports each deliver up to 90W, two 1Gb SFP uplinks handle single- or multi-mode fiber runs back to a NetWay Spectrum head-end, and Altronix's embedded LINQ Technology gives you remote power management and diagnostics over LAN or WAN. This is not a generic IT switch dropped into a security closet — it's purpose-engineered for surveillance and access control edge deployments where remote reboot, real-time alerts, and integrated battery backup matter.

The NETWAYSP4BTX3 is NDAA-compliant, TAA-compliant, BAA-compliant, and CE-listed — making it viable for federal, state, and defense-adjacent projects where supply-chain compliance is a gate, not an afterthought.

Key Features

• 90W Per Port / 360W Total PoE Budget: Each of the four Ethernet ports delivers up to 90W under IEEE 802.3bt, with 360W available across all four simultaneously. That's enough headroom to power the latest multi-sensor PTZ cameras, door controllers with built-in readers, or elevator cameras with integrated heaters — device classes that choke a standard 802.3at (30W) switch.
• IEEE 802.3af / 802.3at / 802.3bt Compliance: All three PoE standards are supported natively. Deploy a mix of legacy 15W cameras alongside new 60W or 90W devices on the same switch without adapter hardware or manual power class configuration — auto-negotiation handles it.
• Dual 1Gb SFP Fiber Uplinks: Two SFP ports support both single-mode and multi-mode fiber transceivers, letting you extend the network segment over distances that CAT6 can't reach. Pair with Altronix P1SM10 (single-mode) or P1MM (multi-mode) transceivers depending on your run length and existing fiber plant.
• Embedded LINQ Technology — Remote Power Management: LINQ enables per-port camera resets, diagnostic polling, and real-time power monitoring from anywhere with LAN or WAN access. Email and Windows Dashboard alerts report events as they happen; an on-board event log retains history. If a camera locks up at 2 AM on a remote parking structure, you can power-cycle the port without rolling a truck.
• Integrated 48VDC Battery Backup Circuit: The built-in 48VDC charging circuit supports sealed lead-acid or gel batteries (sold separately, in a separate ventilated enclosure). On AC loss, failover is instantaneous — no transfer-switch delay that drops PoE devices mid-frame. Critical for deployments where a power interruption cannot mean a gap in coverage.
• Hardened Operating Temperature — -30°C to 65°C: The switch operates reliably from -22°F to 149°F at full 360W load. That covers unheated utility rooms, rooftop IDF enclosures, and parking-structure electrical panels where ambient temperatures swing hard — environments that kill commercial-grade IT switches in the first winter.
• VLAN Management — Up to 10 Groups, 802.1Q Tagged: Segment camera traffic from access control, separate tenant networks, or isolate a compromised device without physical rewiring. ID range 2–4095 gives you enough VLAN headroom for complex multi-tenant or multi-zone site layouts.
• Integral Surge Protection: Built-in surge suppression on all ports — relevant for outdoor-fed runs where lightning-induced transients are a recurring service call rather than a theoretical risk.
• NEMA1 Rated Enclosure: Factory-mounted in a NEMA1 indoor enclosure, wall-mountable out of the box. No field fabrication, no separate DIN-rail hardware required for standard indoor IDF or security-closet installations.
• Auto-Crossover RJ45 on All Four Ports: 10/100/1000 Mbps with auto-negotiation and auto-crossover means no concern about straight-through vs. crossover cabling when swapping out or extending runs — a small but real time-saver during install.

Integration and Compatibility

The NETWAYSP4BTX3 is designed to operate as an edge node in the Altronix NetWay Spectrum fiber distribution architecture. Fiber uplinks connect back to NetWay Spectrum head-end media converters or injectors; Altronix publishes a dedicated Range Calculator to size fiber runs before you order. Compatible SFP transceivers — P1MM (multi-mode), P1SM10 (single-mode), P1AB2K (single-mode kit), and P1GCE (copper) — are sold separately and should be specified at design time based on fiber type and distance.

As a managed PoE network switch, the NETWAYSP4BTX3 integrates into any IP surveillance or access control architecture that uses standard 802.3bt PoE — IP cameras, video intercoms, door controllers, and wireless access points all draw from the same four ports. LINQ Technology connects to the management plane over standard LAN/WAN without proprietary appliances.

For outdoor deployments or sites requiring battery capacity for extended runtime, evaluate the NetWaySP4BTWPX3 variant — it carries the same core switch and power specs in a NEMA4/4X IP66-rated outdoor enclosure with capacity for up to four 12VDC/4AH batteries. If you need a managed solution without the integrated enclosure, the NetWaySP4BTPL3 mounts the same assembly on a backplane. For unmanaged deployments, Altronix offers the NetWaySP41BTX3.

Supply-chain compliance note: the NETWAYSP4BTX3 is verified NDAA Section 889 compliant, TAA-compliant, and BAA-compliant — consult your PoE switch specifications checklist and project compliance requirements before specifying. CE listing covers EU deployments.

Frequently Asked Questions

The spec that stands out on the NETWAYSP4BTX3 is the 90W-per-port 802.3bt budget with 360W available simultaneously across all four ports. In practice, that means you can run four PTZ cameras with integrated heaters, or four multi-sensor panoramic heads, on a single edge node without negotiating power allocation or staggering device boot sequences to stay under budget — a real operational advantage on large-footprint sites like distribution centers or transit hubs.

Technical Highlights:

• LINQ Remote Power Management: Per-port device reset and diagnostic monitoring over LAN or WAN, with email and Windows Dashboard alerting, means you can isolate and recover a frozen camera without dispatching a technician — critical on unmanned remote sites where a truck roll costs more than the device.
• Integrated 48VDC Battery Circuit: Instantaneous failover to battery-backed PoE on AC loss — no 10–50ms transfer gap that drops camera streams mid-event. The 48VDC charging circuit supports sealed lead-acid or gel batteries; size the battery bank separately based on required runtime and total port load.
• Hardened -30°C to 65°C at Full Load: The full 360W operating range holds down to -30°C, which covers unheated mechanical rooms and rooftop IDFs in northern climates where commercial IT equipment fails in the first hard winter.

Deployment Considerations:

• SFP transceivers are not included — specify P1MM or P1SM10 (or P1AB2K kit) based on your fiber plant at design time; missing this on the purchase order is a common delay on first installs.
• Battery enclosure is sold separately and must be ventilated — plan enclosure space and ventilation at the design stage, not during rough-in. The NETWAYSP4BTX3's NEMA1 rating is indoor-only; if your IDF is in an exterior or partially conditioned space, switch to the NetWaySP4BTWPX3 variant before quoting.

The NETWAYSP4BTX3 is the right call for indoor security head-end rooms and hardened IDFs on large commercial campuses, corrections facilities, or transit stations where the combination of 802.3bt power headroom, fiber uplinks, remote LINQ management, and battery failover would otherwise require three separate products mounted in the same cabinet.
