Altronix NETWAYSP2B 2-Port 802.3bt PoE++ Fiber Switch with NEMA4 Enclosure
Overview
The Altronix NETWAYSP2B is a hardened 2-port PoE++ managed switch built for surveillance deployments where a standard rack-mount switch simply cannot survive — think parking structures, loading docks, outdoor utility enclosures, and industrial perimeter installations. It delivers up to 90W per PoE port via IEEE 802.3bt, feeds a 1Gb SFP fiber uplink back to the head-end, and lives inside a NEMA 4/4X, IP66-rated enclosure that shrugs off washdowns and blowing rain. The operating temperature window of -40°C to 75°C means it keeps running in climates where unrated equipment fails within a season. If you're mounting powered devices at the edge of your fiber run and need local PoE injection without a separate power shelf, NETWAYSP2B is the purpose-built answer.
For a broader look at the Altronix surveillance power and networking line, including multi-port variants and integrated enclosure systems, the full catalog covers a wide range of edge-injection scenarios.
Key Features
- 90W per Port via 802.3bt (PoE++): Each of the two PoE ports is rated for up to 90W — the full IEEE 802.3bt ceiling. That's enough headroom for PTZ cameras with integrated heaters, multi-sensor panoramic units, or high-power access control door controllers that would starve an 802.3at (30W) port. Both ports can run simultaneously at full budget given the 180W DC input supply.
- Triple-Standard PoE Compliance (af/at/bt): The switch negotiates correctly with 802.3af (15.4W), 802.3at (30W), and 802.3bt (90W) devices. You won't need to inventory which cameras are which standard before plugging in — the port auto-classifies and delivers accordingly.
- 1Gb SFP Fiber Uplink: The single SFP slot connects back to your NVR or managed switch over fiber, sidestepping copper distance limits and eliminating ground-loop risk on remote runs. Gigabit throughput keeps even high-bitrate multi-stream feeds from saturating the uplink.
- Additional Data Port: A second copper data port (10/100/1000 Mbps, up to 100m) allows a non-PoE device — a secondary controller, a local access point, or a serial-to-IP converter — to share the same enclosure and uplink without consuming a PoE budget slot.
- NEMA 4/4X + IP66 Enclosure: NEMA 4X adds corrosion resistance on top of the washdown protection you get from NEMA 4. IP66 confirms no dust ingress and protection against powerful water jets. For coastal sites, chemical environments, or any outdoor location where condensation and contaminants are real risks, this enclosure rating matters.
- -40°C to 75°C Operating Range: Industrial-grade thermal tolerance in both directions. Cold-climate sites (northern tier parking, outdoor transit hubs) won't see cold-start failures, and sun-exposed enclosures in hot climates won't push the unit into thermal shutdown. The 85°C storage ceiling means temporary warehousing in non-climate-controlled spaces isn't a concern either.
- Dual AC Input Voltage: Accepts 115VAC/60Hz or 230VAC/50-60Hz at the enclosure — ships to international sites or integrates into 230V infrastructure without a separate transformer or voltage converter.
- Compact Switch Board Weight (0.25 lb.): The switch module itself is a quarter pound. The weight figures that matter for shipping and mounting are enclosure-dependent: the WPN enclosure version is 3.7 lb., the WP enclosure is 10.5 lb., and the WPx (largest outdoor enclosure) is 15 lb. Size your conduit knockouts and mounting hardware to the enclosure variant you order, not the bare module.
Integration & Compatibility
The NETWAYSP2B integrates into any IP camera or access control deployment using standard IEEE 802.3af/at/bt PoE devices. Because the uplink is SFP-based, it pairs with any managed switch or media converter accepting a compatible SFP transceiver — single-mode or multimode, depending on your run length. The fiber uplink design makes it a natural fit for long-haul perimeter runs where copper would exceed the 100m Ethernet limit or introduce ground-loop noise issues between buildings. CE European Conformity marks the unit for EU deployments. There are no proprietary management protocols noted in the evidence — the switch operates as a plug-and-play edge injector, appropriate for scenarios where configuration simplicity and physical robustness matter more than per-port VLAN or QoS control.
Frequently Asked Questions
Q: What is the maximum PoE wattage per port on the NETWAYSP2B?
A: Each of the two PoE ports is rated for up to 90W, compliant with IEEE 802.3bt. Both ports can operate simultaneously within the 180W DC input power supply budget.
Q: What PoE standards does the NETWAYSP2B support?
A: The NETWAYSP2B is compliant with IEEE 802.3af (up to 15.4W), 802.3at (up to 30W), and 802.3bt (up to 90W). It will auto-negotiate the correct power class for whichever device is connected.
Q: What type of uplink does the NETWAYSP2B use?
A: It uses a single 1Gb SFP fiber port as its network uplink, allowing long-distance fiber runs back to a head-end switch or NVR without copper distance limitations or ground-loop risk.
Q: What is the enclosure rating on the NETWAYSP2B?
A: The enclosure is rated NEMA 4/4X and IP66, providing protection against dust ingress, direct water jets, and corrosion — suitable for outdoor and industrial installations.
Q: What is the operating temperature range for the NETWAYSP2B?
A: It operates from -40°C to 75°C, covering extreme cold-climate and high-ambient-temperature outdoor environments without additional thermal management.
Q: What input voltages does the NETWAYSP2B accept?
A: The unit accepts 115VAC/60Hz (2.5A) or 230VAC/50-60Hz (1.3A), making it compatible with North American and international power infrastructure without an external transformer.
The NETWAYSP2B addresses one of the more stubborn edge-deployment problems I see regularly: you have two high-draw devices — a PTZ with an integrated heater, a multi-sensor dome, a door controller with a mag-lock relay — and you need to power them from a single outdoor enclosure at the end of a fiber run. The 90W-per-port 802.3bt rating with a 180W total input budget means you're not splitting power between the switch and a separate injector, and you're not having to derate one port because the other is drawing hard.
Technical Highlights:
- 90W/port 802.3bt: Covers the full Class 8 ceiling — enough for a PTZ camera with integrated defroster (typically 60–80W draw) on one port and a high-power access reader or second PTZ on the other, simultaneously.
- -40°C to 75°C operating range: This is a real spec that separates this unit from commercial-grade switches rated to 0°C or -20°C. Northern-tier parking structures and exposed industrial perimeters will test that floor regularly in winter.
- NEMA 4/4X + IP66 enclosure: NEMA 4X adds corrosion resistance that standard NEMA 4 lacks — relevant for coastal, chemical plant, or food-service environments where salt air or cleaning agents reach the enclosure.
Deployment Considerations:
- The switch module itself weighs only 0.25 lb., but your enclosure variant drives the real mounting and conduit planning: the WPN enclosure ships at 3.7 lb. (9.5
