Altronix NETWAYSP41WPN 4-Port PoE+ Managed Media Converter Switch with NEMA 4 Enclosure
Overview
The Altronix NETWAYSP41WPN is a hardened 4-port PoE+ media conversion switch built for outdoor and industrial surveillance installations where a standard rack-mount switch simply won't survive. Packaged inside an IP66/NEMA 4-rated enclosure rated from -40°C to 75°C, it lets you push Gigabit connectivity and up to 30W per port to field-edge cameras, access readers, and intercoms — without running conduit back to a temperature-controlled IDF. Two Gigabit SFP uplink ports handle the fiber backhaul, making it a natural fiber-to-copper transition point at the edge of an outdoor IP camera run.
This unit draws 48–56VDC input — not a 120VAC wall plug — so plan your power architecture accordingly. It belongs in a junction box, a pole mount, or a curbside cabinet where a DC power source (such as a dedicated Altronix power supply or a centralized DC distribution panel) is already present. If you're building a new IP camera deployment that terminates fiber at the edge, the NETWAYSP41WPN is purpose-built for that topology.
Key Features
- 120W Total PoE+ Budget Across 4 Ports: With a 120W pool shared across four 802.3at ports, you can run four 30W devices simultaneously — enough headroom for PTZ cameras, multi-sensor domes, or heated housings. No port-budget math gymnastics, just full 30W at every port if you need it.
- Four 10/100/1000 Mbps PoE+ Ports (802.3af/at): Gigabit copper to every endpoint means you're not bottlenecking 4K or multi-stream cameras at 100Mbps. The 802.3af backward compatibility means standard PoE devices draw what they need without any manual configuration.
- Two Gigabit SFP Uplink Ports: Fiber uplinks eliminate distance constraints on the backhaul run. Copper Ethernet tops out around 100m; fiber spans can reach well beyond that depending on the SFP modules you install — useful when the nearest switch is hundreds of meters away in a main building.
- IP66 / NEMA 4 and NEMA 4X Enclosure: IP66 means no ingress from rain, hose-down, or windblown debris — this unit can live on an exterior wall or inside a curbside cabinet exposed to the elements. NEMA 4X adds corrosion resistance, relevant in coastal, chemical, or food-processing environments. Skip this if your enclosure is fully climate-controlled; otherwise it's exactly the right rating for outdoor edge gear.
- -40°C to 75°C Operating Range: Whether you're commissioning in a Minnesota January or a Phoenix July, the operating window handles both extremes without supplemental heating or cooling. Storage down to -85°C means the unit ships to and sits in a warehouse in Alaska without issue.
- 48–56VDC Input Voltage: The DC-only input matches the output of most dedicated surveillance power plants. This is not a wall-outlet device — it slots into a DC-powered infrastructure. That's a deliberate design choice: DC distribution at the edge is more stable and easier to battery-back than AC.
- 100m Copper Reach Per Port: Standard 100m Ethernet run from switch port to camera or reader. Pair with the SFP uplinks and you cover nearly any campus or perimeter topology without signal repeaters.
- 85% RH Humidity Tolerance: Rated to 85% ±5% relative humidity, so condensation from thermal cycling in an outdoor enclosure won't degrade performance over time.
Integration and Compatibility
The NETWAYSP41WPN integrates into any Ethernet-over-fiber surveillance or access control backbone. The dual SFP slots accept standard Gigabit SFP modules (single-mode, multimode, or BiDi) — choose your transceiver based on the fiber type and run length already in place. On the copper side, it's compatible with any 802.3af or 802.3at powered device: PTZ cameras, fixed IP cameras, VoIP intercoms, card readers, and wireless APs. No proprietary cabling or connectors.
Because the unit requires 48–56VDC input, plan around a matching DC power supply or battery-backed power plant at the cabinet. Altronix's own power distribution line integrates cleanly, but any regulated DC source in range works. The enclosure's NEMA 4 rating also means you can surface-mount it on an exterior wall or inside a non-climate-controlled equipment cabinet without additional weatherproofing.
For system architects designing a PoE network switch infrastructure at the edge of a large perimeter or campus deployment, this unit eliminates the need to pull a dedicated fiber home-run for every camera cluster — one fiber uplink serves up to four endpoints at the field node.
Frequently Asked Questions
Q: What is the maximum PoE wattage per port on the NETWAYSP41WPN?
A: Each of the four PoE+ ports supports up to 30W (IEEE 802.3at), with 120W available across all four ports simultaneously — meaning all four ports can run at full 30W load concurrently.
Q: What input voltage does the NETWAYSP41WPN require?
A: The NETWAYSP41WPN requires 48–56VDC input. It is not an AC-powered device and requires a compatible DC power source or distribution panel.
Q: What fiber modules are compatible with the two SFP ports?
A: The SFP slots accept standard Gigabit SFP transceivers. Module selection (single-mode, multimode, BiDi) depends on your existing fiber infrastructure and run distance. Altronix does not restrict you to proprietary modules.
Q: Can the NETWAYSP41WPN be mounted outdoors without an additional enclosure?
A: Yes. The unit's IP66 and NEMA 4/4X-rated enclosure is designed for direct outdoor installation — it withstands rain, windblown debris, and hose-down conditions. NEMA 4X adds corrosion resistance for harsh environments.
Q: What is the operating temperature range of the NETWAYSP41WPN?
A: Operating range is -40°C to 75°C (-40°F to 167°F), covering extreme cold and heat without supplemental climate control. Storage temperature extends to -40°C to 85°C.
Q: Does the NETWAYSP41WPN support both 802.3af and 802.3at PoE devices?
A: Yes. All four ports are backward-compatible with IEEE 802.3af (up to ~15.4W) and forward-compatible with IEEE 802.3at PoE+ (up to 30W). Standard PoE devices will negotiate the correct power class automatically.
The spec I keep coming back to on the NETWAYSP41WPN is the -40°C to 75°C operating range combined with IP66/NEMA 4 housing. Most integrators solve outdoor edge switching with an indoor switch stuffed into a heated cabinet — that works, but it adds cost, complexity, and a heat element that can fail. This unit eliminates that entire layer. I've deployed similar Altronix edge nodes at perimeter fence lines where ambient swings from -30°C in winter to 55°C inside a sun-baked steel cabinet in summer, and a unit with a 75°C ceiling handles that without derating.
Technical Highlights:
- 120W / 30W-per-port PoE+ Budget: Full 30W available at all four ports simultaneously — run four PTZ cameras or heated camera housings at max draw without port throttling. That's the ceiling most 4-port edge switches can't hit.
- Dual Gigabit SFP Uplinks: Two fiber uplinks give you redundant backhaul paths or the ability to daisy-chain edge nodes across a perimeter without pulling copper. Your SFP choice governs the span — single-mode modules can push this to kilometers.
- 48–56VDC Input: DC input matches the output rail of virtually every commercial surveillance power plant. Battery backup integration is straightforward — your UPS sits on the DC bus, not on an inverter chain.
Deployment Considerations:
- Plan your DC source before specifying this unit — 48–56VDC at sufficient amperage to support 120W PoE output plus switch overhead is not trivial. Size your power supply for the full 120W load plus supply inefficiency margin.
- The SFP slots are unpopulated — budget for appropriate transceivers based on your fiber type and distance. Ordering the switch without confirmed SFP module specs is a common field delay.
The NETWAYSP41WPN is the right call for perimeter fence-line camera clusters, parking structure junction boxes, and outdoor access control head-end cabinets where you're terminating fiber and distributing PoE to four endpoints from a single hardened node — particularly in climates that rule out standard commercial switching gear.
