Altronix NETWAYSP41BTWPN 4-Port 802.3bt Managed PoE Switch with NEMA 4/4x Enclosure

Overview

The Altronix NETWAYSP41BTWPN is a hardened, outdoor-rated managed PoE switch built for surveillance and security infrastructure deployments where weather exposure, extreme temperatures, and high per-port power demands rule out standard rack equipment. It delivers four 10/100/1000 Mbps PoE ports at up to 90W each — enough to drive 802.3bt (PoE++) cameras, multi-sensor units, and PTZ heads without external injectors — alongside two Gigabit SFP uplink slots for fiber connectivity back to the head-end. Housed in a NEMA 4/4x (IP66-11) enclosure, it's rated from -40°C to 75°C, making it a viable choice for parking structures, loading docks, rooftop mounts, and any outdoor cabinet installation where condensation, rain, and temperature swings are the norm rather than the exception.

The NETWAYSP41BTWPN is part of Altronix's Altronix NetWay LINQ series, a family of LINQ-enabled managed switches designed specifically for physical security integrators who need remote diagnostics and per-port power control without standing up a full enterprise network management stack.

Key Features

802.3bt (PoE++) at 90W per port: Each of the four data ports can supply up to 90W — the full 802.3bt Class 8 ceiling. That means a single port can power a multi-sensor panoramic camera or a high-speed PTZ with onboard heating, eliminating the need for a separate midspan injector or local power supply at the pole or junction box. Across all four ports, the switch carries a 320W total power budget, so plan your port assignments if you're running all four at heavy load simultaneously.

320W total PoE power budget: 320W shared across four ports gives you real flexibility — run two 90W PTZs and two 30W fixed cameras without hitting the ceiling, but the budget doesn't support four simultaneous 90W draws (360W total). Map your per-device draw before finalizing the design to avoid post-installation surprises.

2 × Gigabit SFP uplink slots: Fiber uplinks let you connect back to the head-end NVR or core switch over single-mode or multimode fiber — essential when the switch is mounted on a pole or exterior wall far from the nearest copper distribution point. Two SFP slots provide uplink redundancy options or the ability to connect into a ring topology for path resilience.

NEMA 4/4x, IP66-11 enclosure: NEMA 4/4x means the enclosure withstands windblown rain, splashing water, hose-directed water, and corrosion — appropriate for exposed outdoor mounting without an additional weatherproof cabinet. IP66-11 confirms the same protection level under the IEC rating scheme. This is not a pressurized or submersion-rated enclosure; if the installation sits in a flood zone, plan accordingly.

-40°C to 75°C operating range: A -40°C cold-start rating covers virtually every North American and Northern European climate without supplemental enclosure heating. The 75°C upper limit provides headroom in direct-sun rooftop installations where black metal enclosures can absorb significant radiant heat in summer. Storage is rated to -40°C / 85°C, so cold-storage pre-staging doesn't require special handling.

4 × 10/100/1000 Mbps auto-negotiating ports: Gigabit copper to each camera keeps the access layer future-proof — even as camera bitrates climb with higher resolution and more analytics streams, the port won't become a bottleneck. Auto-negotiation means legacy 100Mbps endpoints connect without manual configuration.

LINQ management integration: The LINQ architecture gives integrators remote visibility into port status, power cycling, and diagnostics — useful for troubleshooting a frozen camera or resetting a PoE device without a truck roll. This is particularly valuable in distributed deployments where the switch is mounted 20 feet up a parking structure column.
