Altronix NETWAY4E1BTX3 4-Port PoE++ Managed Switch with SFP Uplink
Overview
The Altronix NETWAY4E1BTX3 is a hardened, self-contained PoE++ switch designed for surveillance deployments where high-wattage edge devices — PTZ cameras, multi-sensor units, pan-tilt heads, access control panels — need reliable power and data from a single enclosure rated for outdoor or industrial environments. It delivers 360W of total PoE budget across four ports, supports 802.3bt (90W per port), and ships inside a NEMA 4/4X, IP66-rated steel enclosure that handles direct washdown and sub-zero temperatures. If you are running a PoE switch infrastructure for perimeter or parking coverage, this unit eliminates the need for a separate outdoor cabinet.
Key Features
- 802.3bt PoE++ at 90W per port: Full 90W per port means you can drive any device on the market — 4K PTZ cameras, multi-sensor domes, heated enclosures, and access controllers all draw within this ceiling. No need to split power or compromise device selection.
- 360W total power budget: At 54VDC / 6.4A output, the unit can sustain all four ports simultaneously under heavy load without throttling. Budget 90W per port worst case and you are fully covered across a four-camera run.
- Four 10/100/1000 Mbps PoE ports + one Gigabit SFP: The four copper ports handle device connections; the SFP uplink connects to your core switch or fiber backbone. Using fiber on the uplink gives you electrical isolation and removes the 100m copper distance limit on your network run — useful for perimeter installations where the IDF is far from the enclosure.
- NEMA 4/4X and IP66-rated steel enclosure: NEMA 4X covers rain, sleet, dust, and corrosion resistance. IP66 means no ingress from directed water jets. This enclosure can be surface-mounted to an exterior wall or pole without a separate weatherproof cabinet, cutting both install time and hardware cost.
- -30°C to 70°C operating range: Few commercial switches operate reliably below -10°C. This unit is rated to -30°C, making it viable in northern climates, cold-storage facilities, and unheated parking structures where a standard switch would brown out in winter.
- Dual voltage input (115VAC or 230VAC): Accepts either standard US line voltage or international 230VAC without a transformer swap — useful on sites with mixed electrical infrastructure or for integrators who stock one SKU for multiple regions.
- CE agency listing: CE marking confirms compliance with European electromagnetic and safety directives, which is relevant for international project bids or installations on EU-registered facilities.
- 183 BTU/hr heat dissipation: At full 360W PoE load, the unit dissipates 183 BTU/hr. That is a real number to factor into any enclosure thermal calculation — ventilated mounting positions will extend component life in hot climates.
Integration and Compatibility
The NETWAY4E1BTX3 supports PTZ cameras and other high-draw devices via 802.3bt, and is compatible with any 802.3af/at/bt end device — no proprietary handshake required. The Gigabit SFP uplink accepts standard SFP modules for single-mode or multimode fiber runs, integrating cleanly into existing network switch architectures. For Altronix ecosystem deployments, it is designed to work within the LINQ network management platform and alongside BC300-series power accessories. Review your PoE planning guide before sizing cable runs — 90W loads on long CAT6 runs can introduce voltage drop that affects delivered wattage at the device.
Frequently Asked Questions
Q: Can the NETWAY4E1BTX3 deliver 90W on all four ports simultaneously?
A: Yes. The unit is rated for 360W total output at 54VDC/6.4A, which supports four ports at 90W each running concurrently.
Q: What SFP modules are compatible with the uplink port?
A: The uplink is a standard Gigabit SFP slot. Standard 1G SFP modules for single-mode or multimode fiber are compatible; verify SFP interoperability with Altronix before deploying third-party modules.
Q: Is the NETWAY4E1BTX3 suitable for outdoor installation without an additional enclosure?
A: Yes. The integrated NEMA 4/4X, IP66-rated steel enclosure is designed for direct outdoor surface mounting. No secondary weatherproof cabinet is required.
Q: What is the minimum operating temperature for this unit?
A: The NETWAY4E1BTX3 is rated to -30°C (-22°F), making it viable for cold-storage, northern climate, and unheated structure deployments.
Q: Does the NETWAY4E1BTX3 support legacy 802.3af and 802.3at devices?
A: Yes. The unit supports 802.3af, 802.3at, and 802.3bt standards, so it works with any standards-compliant PoE device regardless of wattage class.
The NETWAY4E1BTX3 is the unit I reach for when a perimeter installation has high-draw PTZ cameras, the IDF is more than 100 meters away, and the integrator does not want to build a separate outdoor cabinet. The 360W PoE budget at 90W per port is the real differentiator — most compact outdoor switches cap out at 30W or 60W per port, which rules them out for 4K multi-sensor or heated-enclosure applications.
Technical Highlights:
- 90W per port (802.3bt): Full Class 8 PoE++ means you are not choosing devices based on what the switch can power — every current high-wattage device fits within this ceiling.
- -30°C to 70°C operating range: This is a 100°C swing. In practice, it means the unit survives a Minnesota winter in an unheated parking structure without a thermostatically controlled heater pad — a real cost saving on cold-climate jobs.
- NEMA 4X / IP66 enclosure: NEMA 4X adds corrosion resistance beyond standard NEMA 4 — relevant for coastal sites, wastewater facilities, or any installation where salt air or chemical wash-down is a factor.
Deployment Considerations:
- At 183 BTU/hr heat dissipation under full 360W PoE load, mount the unit in a ventilated position or shaded location in hot climates — a south-facing wall in direct sun in Phoenix will stress the enclosure thermal envelope.
- The 5A/250V input fuse is the upstream protection point — confirm your circuit breaker and wire gauge match this draw before commissioning, especially on 115VAC circuits where inrush on four simultaneous 802.3bt devices can momentarily spike current.
This unit is well-matched for parking structure perimeter coverage, cold-storage facility camera runs, and outdoor access control head-end consolidation — anywhere you need full 802.3bt wattage inside a self-contained enclosure without running conduit back to an indoor IDF.
