Altronix NETWAY4EBTWPX3 4-Port 802.3bt PoE Switch with NEMA 4X Enclosure and Battery Backup

Overview

The Altronix NETWAY4EBTWPX3 is a hardened 4-port Gigabit PoE switch engineered for outdoor and harsh-environment surveillance installations where a standard indoor switch simply won't survive. It combines 802.3bt (90W per port) PoE delivery, a single SFP uplink port, and a 360W power supply inside a NEMA 4/4X-rated enclosure that carries an IP66 ingress rating — all in one self-contained unit designed to be field-mounted at the edge of your network, not in a conditioned equipment room.

This is an Altronix product built around the same design philosophy as the rest of their surveillance networking and power line: consolidate the switch, power supply, and battery backup into a single enclosure to reduce wiring runs, eliminate separate cabinet hardware, and give field technicians a repeatable, serviceable installation unit.

Key Features

• 802.3bt PoE at 90W per port: Each of the four ports delivers up to 90W — the full 802.3bt Class 8 budget. That means you can power high-wattage PTZ cameras, multi-sensor panoramic cameras, or any PoE-powered device that would starve on 802.3at (30W) or even 802.3af (15.4W). No injectors, no mid-span adapters — just wire the camera direct.
• 360W total power output at 54VDC/6.4A: The 360W envelope is shared across all four ports. If your device mix is heavier on high-draw endpoints (pan-tilt-zoom cameras with heaters, for example), plan your port allocation before installation — four devices simultaneously drawing 90W each will hit the ceiling. More commonly, a mixed deployment of 25–60W cameras leaves comfortable headroom.
• Gigabit Ethernet on all ports (10/100/1000 Mbps): Gigabit throughput on every data port matters when you're aggregating multiple high-resolution camera streams — a 4K camera at 15–20 Mbps times four endpoints chews through Fast Ethernet headroom quickly. Gigabit keeps you clear of bandwidth bottlenecks at the edge.
• 1x SFP uplink port: The SFP slot lets you run fiber back to your core switch or NVR — critical when the enclosure is mounted at distance from the head-end equipment room. Fiber eliminates ground-loop exposure on long outdoor cable runs and gets you past the 100-meter copper Ethernet limit without a media converter in a separate enclosure.
• NEMA 4/4X enclosure rated IP66: NEMA 4X adds corrosion resistance beyond standard NEMA 4 — relevant in coastal, chemical, or wash-down environments. IP66 means sustained, high-pressure water jets won't penetrate the housing. If your mounting location sees power washing, road spray, or salt air, this enclosure rating is the spec to look for. It is not rated for submersion, so avoid low-lying installations subject to flooding.
• -30°C to 70°C operating range: This is a genuinely wide thermal envelope. The lower bound handles northern U.S. and Canadian winters without enclosure heaters on the electronics. The 70°C upper limit is equally important — a sealed enclosure in direct summer sun can trap considerable heat, and most standard switches derate or fail above 50°C. Storage temperature extends to -30°C to 85°C.
• Integrated battery backup (48VDC, 0.75A, sealed lead-acid or gel): The built-in battery charger supports sealed lead-acid or gel-type batteries at 48VDC/0.75A. This gives connected cameras continued operation during brief AC power interruptions — a meaningful feature on perimeter installations where UPS coverage from the central equipment room isn't practical. Battery capacity and runtime depend on the battery you install; the unit provides the charging and management infrastructure.
• Dual AC input voltage (115VAC 60Hz or 230VAC 50/60Hz): Auto-ranging input means the same unit deploys in North American 120V infrastructure or international 230V environments without a transformer or hardware swap — useful for enterprise customers with multinational deployments or projects where the local supply voltage isn't confirmed until installation day.

Integration and Compatibility

The NETWAY4EBTWPX3 fits naturally into any IP camera deployment where the switch needs to live at the camera cluster rather than in a central IDF. The 802.3bt standard is backward-compatible with 802.3at and 802.3af devices — connect lower-wattage cameras and they'll negotiate the correct power class automatically. The SFP uplink integrates with any fiber-capable core switch or managed PoE aggregation layer.

Battery type is field-selectable (sealed lead-acid or gel); consult your AHJ and the battery manufacturer for enclosure compatibility if the installation environment has temperature extremes near the operating limits. The NEMA 4X rating qualifies the enclosure for use in many industrial and outdoor applications governed by NEC and NFPA standards, though verification against the specific jurisdiction's requirements is the integrator's responsibility.

Frequently Asked Questions

Q: What is the maximum wattage the NETWAY4EBTWPX3 can deliver per port?

A: Each port supports up to 90W via the 802.3bt (PoE++) standard. The total system power budget is 360W shared across all four ports, so simultaneous full-load on all ports (4 × 90W = 360W) is at the ceiling — plan your device mix accordingly.

Q: Can the NETWAY4EBTWPX3 be used in outdoor installations in cold climates?

A: Yes. The operating temperature range is -30°C to 70°C (-22°F to 158°F), which covers most North American outdoor winter conditions without supplemental enclosure heating for the electronics. The NEMA 4/4X, IP66-rated enclosure provides weather sealing for rain, dust, and high-pressure water jets.

Q: What type of battery does the NETWAY4EBTWPX3 use for backup power?

A: The unit is compatible with sealed lead-acid or gel-type batteries at 48VDC. The integrated charger operates at 0.75A. Battery capacity — and therefore backup runtime — depends on the battery you install; the NETWAY4EBTWPX3 provides the charging circuit and housing infrastructure.

Q: Does the NETWAY4EBTWPX3 support fiber uplinks?

A: Yes. There is one SFP port for fiber or copper SFP modules, allowing a fiber uplink to your core switch or NVR head-end. This is particularly valuable when the enclosure is mounted at distance exceeding the 100-meter copper Ethernet limit, or where ground-loop isolation on long outdoor cable runs is a concern.

Q: Is the NETWAY4EBTWPX3 compatible with both 120V and 240V AC power?

A: Yes. The unit accepts 115VAC at 60Hz or 230VAC at 50/60Hz, making it suitable for both North American and international electrical infrastructure without hardware modification.

Q: Will the NETWAY4EBTWPX3 work with standard 802.3af and 802.3at PoE cameras?

A: Yes. 802.3bt is backward-compatible with 802.3at (PoE+, up to 30W) and 802.3af (PoE, up to 15.4W) devices. Connected cameras and other endpoints negotiate the appropriate power class automatically.
