Altronix NETWAYSP41BTWPX 4-Port 802.3bt PoE++ Managed Switch with NEMA 4X Enclosure and Battery Backup

Overview

The Altronix NETWAYSP41BTWPX is a hardened, outdoor-rated PoE network switch purpose-built for surveillance and access control deployments where the network edge has to survive weather extremes, power disruptions, and multi-device high-wattage loads simultaneously. Housed in a NEMA 4/4X, IP66-rated steel enclosure, it delivers four 10/100/1000 Mbps PoE++ ports plus two Gigabit SFP uplinks — with up to 90W per port and 240W total system output. If you've been hunting for a switch that handles PTZ cameras, multi-sensor panoramics, and IP intercoms without an external UPS bolted alongside, this form factor addresses that problem directly.

It integrates into the Altronix LINQ managed power and networking platform, giving installers centralized remote monitoring and control of each port's power state — useful on sites where rebooting a frozen camera or door controller means a 45-minute truck roll otherwise.

Key Features

• 90W Per-Port PoE++ (802.3bt): Each of the four PoE ports delivers up to 90W independently — enough to power a high-wattage PTZ camera, a multi-sensor unit, or an IP video door station without a separate injector or mid-span. The 802.3bt standard also maintains backward compatibility with 802.3at (30W) and 802.3af (15.4W) devices, so legacy cameras on the same switch don't require hardware changes.
• 240W Total System Budget: With 240W available across the four ports, you can run four power-hungry endpoints simultaneously at near-maximum draw without starving any port. Budget each camera's actual wattage against this ceiling before deploying — heater-equipped outdoor PTZs can approach 60–80W in cold weather, which affects how many you can string from this single switch.
• Dual Gigabit SFP Uplinks: Two SFP slots let you extend fiber connectivity back to the head-end or ring switches without running copper — critical for fiber-fed outdoor camera runs over 100 meters or wherever electrical isolation between buildings is required. Single-mode or multi-mode modules fit the standard SFP cage.
• NEMA 4/4X and IP66 Enclosure: The steel enclosure is rated NEMA 4/4X and IP66 — that means rain, sleet, hose-down cleaning, and blowing dust are non-issues. NEMA 4X specifically adds corrosion resistance, which matters for coastal sites, food-processing environments, and anywhere periodic washdowns occur. If you need full submersion tolerance, you'd need IP67 or higher; IP66 does not cover that.
• -30°C to 55°C Operating Range: The switch stays operational from -22°F up to 131°F — suited for unheated equipment boxes in northern climates and rooftop enclosures in hot-summer regions. The lower -30°C bound means it won't cold-fail on a January morning in Minnesota or Alberta without supplemental heating.
• Battery Backup — LiFePO or SLA/Gel: The NETWAYSP41BTWPX supports both LiFePO (lithium iron phosphate) and sealed lead acid or gel batteries, giving you a choice between longer cycle life and lower weight (LiFePO) or lower upfront cost (SLA). This is an integrated UPS function — connected cameras stay live during a power outage without a separate UPS module mounted externally.
• 115VAC or 230VAC Input: Dual-voltage AC input means the unit ships and installs on either North American or international power grids without a transformer or voltage converter. On international projects, this eliminates a common line-item from the BOM.
• 56VDC Output for PoE Delivery: The 56VDC output rail sits above the 54V nominal used by 802.3bt-compliant devices, giving the power budget some headroom to compensate for line losses over longer cable runs. On 100-meter runs, that margin matters for maintaining a stable PoE negotiation.
• LINQ Platform Integration: LINQ connectivity gives you remote per-port power cycling, power consumption monitoring, and alarm notifications — capabilities that move this beyond a dumb switch into a managed power-networking node. For multi-site operators, the ability to reboot a frozen camera controller remotely has real operational value.
• Compact Form Factor for Pole and Cabinet Mounting: At 17.53" × 15.3" × 6.67" and 15 lb., the unit fits in a standard outdoor NEMA enclosure or mounts directly in a pole-mounted cabinet. Confirm enclosure interior clearances before ordering — the depth at 6.67" can be tight in shallow cabinets.

Integration & Compatibility

The NETWAYSP41BTWPX integrates into deployments that use ONVIF-compliant IP cameras, IP access control readers, IP intercoms, and any 802.3af/at/bt endpoint. The SFP ports accept standard Gigabit SFP transceivers, so it slots into most fiber-backhaul topologies without vendor lock-in on the fiber side. For sites running a video management system — Milestone, Genetec, Exacq, or similar — the switch's network function is transparent; VMS compatibility is determined by the cameras and NVR, not the switch itself. The LINQ management interface communicates over the network and requires a compatible Altronix network management platform to unlock remote power-control features. Verify LINQ compatibility with your Altronix distributor before assuming standalone LINQ access is available without additional controller hardware.

Frequently Asked Questions

Q: What is the maximum wattage this switch can deliver to a single PoE port?

A: Each of the four PoE ports on the NETWAYSP41BTWPX supports up to 90W per port under the 802.3bt standard. Total system PoE budget across all four ports is 240W, so plan your per-port loads accordingly — running all four ports simultaneously at 90W exceeds the total budget.

Q: Can the NETWAYSP41BTWPX be installed outdoors without an additional enclosure?

A: Yes. The unit ships in a NEMA 4/4X-rated, IP66-rated steel enclosure, which is designed for outdoor installation and resists rain, hose-directed water, and dust intrusion. It is not rated for submersion. Verify that mounting hardware and cable entry points are properly sealed during installation to maintain the IP66 rating.

Q: What battery types are compatible with the built-in backup power system?

A: The NETWAYSP41BTWPX supports both LiFePO (lithium iron phosphate) and sealed lead acid or gel batteries. LiFePO offers longer cycle life and lighter weight; SLA/gel batteries are generally lower cost upfront. Battery runtime depends on the battery capacity you select and the total load on the PoE ports at the time of outage.

Q: Does the NETWAYSP41BTWPX support legacy 802.3af and 802.3at cameras?

A: Yes. The switch is backward-compatible with 802.3af (up to 15.4W) and 802.3at (up to 30W) devices in addition to 802.3bt (up to 90W). You can mix camera generations on the same switch without adapters or injectors.

Q: What input voltage does the NETWAYSP41BTWPX require?

A: The unit accepts either 115VAC or 230VAC input, making it compatible with both North American and international power standards without a voltage converter.

Q: What temperature range does the NETWAYSP41BTWPX support?

A: The operating temperature range is -30°C to 55°C (-22°F to 131°F), suitable for cold-climate outdoor enclosures and hot-roof cabinet installations without supplemental heating in most regions.

The spec I keep coming back to on the NETWAYSP41BTWPX is the 90W-per-port 802.3bt delivery in an already-enclosed outdoor package. Most integrators bolt a PoE++ switch inside a separate NEMA box — here that's already solved, and you get battery backup in the same assembly. That combination cuts BOM complexity and installation labor on remote camera stations significantly.

Technical Highlights:

• 90W Per-Port 802.3bt: Handles the highest-draw IP devices — multi-sensor panoramics, IR PTZs with built-in heaters/blowers, high-power intercoms — without mid-spans or injectors. At 240W total, you can run four 60W PTZs simultaneously with headroom.
• Integrated Battery Backup (LiFePO or SLA): Unlike a standalone switch that drops endpoints the moment AC fails, the NETWAYSP41BTWPX keeps PoE devices live through outages. LiFePO chemistry is the better long-term choice for outdoor installs — it handles the -30°C to 55°C range better than SLA and won't sulfate from partial-state cycling.
• Dual Gigabit SFP Uplinks: Two SFP slots let you run fiber back to a head-end switch, which is often the right call when the camera node is 150–300 meters from the server room or across a parking lot where ground potential differences make copper a liability.

Deployment Considerations:

• At 15 lb. and 6.67" deep, verify cabinet interior depth before ordering — shallow pole-mount cabinets can be a tight fit, and you need clearance for battery connections and cable management behind the unit.
• The 240W total budget does not equal four simultaneous 90W ports — confirm your per-port load profile before design sign-off. A heated PTZ drawing 75W plus three 45W multi-sensors already pushes 210W, leaving limited margin for startup inrush.

This unit is the right call for remote outdoor camera nodes — parking structures, perimeter fence lines, loading dock clusters — where running AC back to a central IDF is impractical and you need the switch, the power budget, and the UPS function in a single weatherproof assembly that survives a Minnesota winter without a site visit.
