Altronix NETWAY4E1LWPX Hardened Outdoor PoE+ Switch with Fiber Uplink and LiFePO4 Battery Backup
Overview
The Altronix NETWAY4E1LWPX is a hardened Gigabit PoE+ managed switch built for outdoor surveillance deployments where both fiber connectivity and battery-backed power continuity are requirements — not afterthoughts. It ships in a NEMA4/IP66-rated enclosure rated for operation from -40°C to 75°C, making it a legitimate candidate for exposed pole-mount or rooftop edge nodes in demanding climates. Four PoE+ ports power cameras or edge devices at up to 30W each (75W total pool), while a single Gigabit SFP port carries the fiber uplink back to the core — eliminating the copper distance ceiling and the ground-loop problems that come with running conductors between buildings. NDAA, TAA, BAA, and CE compliance make the NETWAY4E1LWPX a viable procurement option for federal, state, and municipality projects where supply-chain documentation matters.
Key Features
- 4 x Gigabit PoE+ Ports (30W/port, 75W total): Each of the four RJ45 ports delivers up to 30W — enough headroom for dual-stream PTZ cameras, license-plate capture units, or AI-enabled edge cameras pulling near-full 802.3at budgets. The 75W pool is the binding constraint, so if you're loading all four ports with high-draw devices, plan port assignments against that ceiling, not the per-port max.
- 1 x Gigabit SFP Fiber Uplink: The SFP slot accepts standard 1000Base-X modules (not included — see compatible P1MM, P1SM10, or P1AB2K). Fiber eliminates the 100m copper-run limit and any ground-potential difference between structures — critical on large campuses or outdoor installations where building-to-building copper creates ground-loop artifacts that corrupt video feeds.
- Integrated LiFePO4 Battery Charger: The built-in charger supports a single 12V Lithium Iron Phosphate battery (BTL125, 4.5AH, sold separately). LiFePO4 chemistry gives you substantially more charge/discharge cycles and longer calendar life versus SLA — meaningful when the battery is sealed inside an outdoor enclosure and isn't being swapped annually. On AC loss, the unit automatically switches to battery. Do not connect lead-acid or gel batteries — the charger profile is chemistry-specific and will damage incompatible batteries.
- NEMA4/IP66 Enclosure, -40°C to 75°C Operating Range: The sealed enclosure handles wind-driven rain and dust ingress without additional weatherproofing. The -40°C floor matters in northern climates where switch electronics in unheated enclosures fail at the temperature limits that most commercial-grade units don't publish. Note: if a LiFePO4 battery is installed inside the enclosure, the effective operating temperature narrows to 0°C–40°C — plan battery placement accordingly in extreme-cold deployments.
- IEEE 802.3af/at Compliance with Integral Surge Protection: Both PoE standards are supported, so legacy 802.3af-only cameras work alongside newer 802.3at devices on the same switch. Surge protection is built in — relevant for outdoor nodes exposed to indirect lightning strikes on long cable runs.
- Auto-Crossover, Auto-Negotiation on All Copper Ports: 10/100/1000 Mbps half/full duplex auto-negotiation with auto-crossover on Cat5 or better means no configuration overhead and no need for crossover cables during installation.
- Per-Port LED Status Visibility: Individual PoE On, IP link status, and 100/1000 Base-T/active LEDs on each port, plus an ALOS LED for SFP fiber link status and a Heartbeat LED for overall unit health — useful for field troubleshooting without connecting a laptop to the unit.
- TAA, NDAA, BAA, CE Compliance: NDAA Section 889 compliance means the switch is cleared for federal facility surveillance systems. TAA compliance satisfies GSA schedule and government procurement requirements. BAA compliance supports Buy American provisions on eligible contracts.
Integration and Compatibility
The NETWAY4E1LWPX integrates into any Altronix network power infrastructure deployment and is compatible with any PoE or PoE+ compliant edge device — cameras, intercoms, access readers, or wireless APs — connected via Cat5 or better over RJ45. The fiber SFP uplink is compatible with third-party SFP transceivers meeting 1000Base-X Class 1 laser specifications; Altronix offers matched P1MM (multi-mode), P1SM10 (single-mode), P1AB2K (single-mode kit), and P1GCE (copper SFP) modules for a validated configuration. Pair with the PoE switch infrastructure upstream or with NetWaySP1A PoE-powered fiber media converters to extend reach further. For deployments requiring pole attachment, the PMK2 Pole Mount Kit is the factory-matched accessory. The BTL125 4.5AH LiFePO4 battery is the only Altronix-specified battery for this unit — using third-party batteries voids the chemistry assumptions of the built-in charger. Review your PoE power budgeting guide before assigning port loads; the 75W total pool on four 30W-rated ports creates a constraint that's easy to overprovision in design. For broader outdoor IP camera deployments, confirm that your camera PoE draw at operating temperature matches the port budget — some high-performance cameras throttle PoE requests upward as resolution and analytics load increases. Altronix's NetWay Spectrum Range Calculator (available via Altronix's support resources) can assist with range and power planning before installation.
Frequently Asked Questions
Q: Is the NETWAY4E1LWPX NDAA Section 889 compliant?
A: Yes. The NETWAY4E1LWPX carries NDAA, TAA, BAA, and CE compliance listings, making it suitable for federal, state, and government-funded surveillance projects with supply-chain restrictions.
Q: What battery does the NETWAY4E1LWPX support, and is it included?
A: The NETWAY4E1LWPX is designed exclusively for a single 12V LiFePO4 (Lithium Iron Phosphate) battery. Altronix's compatible battery is the BTL125 (4.5AH), sold separately. Lead-acid and gel batteries must not be used — the integrated charger is calibrated for LiFePO4 chemistry only.
Q: What SFP modules are compatible with the NETWAY4E1LWPX fiber port?
A: The SFP slot accepts any 1000Base-X Class 1 laser-compliant Gigabit SFP module. Altronix-compatible options include the P1MM (multi-mode), P1SM10 (single-mode), P1AB2K (single-mode kit), and P1GCE (copper transceiver). SFP modules are not included with the unit.
Q: Does the battery temperature range affect outdoor installation planning?
A: Yes, importantly. The switch itself operates from -40°C to 75°C without a battery. However, if a LiFePO4 battery is installed inside the enclosure, the safe operating temperature range for that configuration narrows to 0°C to 40°C. In sub-zero climates, the battery must be managed or relocated to maintain the full switch operating range.
Q: Can the NETWAY4E1LWPX be pole-mounted outdoors?
A: Yes. The NEMA4/IP66-rated enclosure is designed for outdoor installation. Altronix's PMK2 Pole Mount Kit is the factory-specified accessory for pole attachment. The Vent2 accessory provides additional air venting for NEMA4/4X enclosures if thermal management is needed.
Q: What is the total PoE power budget across all four ports?
A: Each port is rated at 30W (802.3at), but the total system power output is capped at 75W across all four ports. If you load all four ports with full 802.3at devices, you will exceed the 75W cap — plan port loads accordingly and prioritize higher-draw devices against available budget.
The NETWAY4E1LWPX is one of the few edge switches I recommend when a project simultaneously needs fiber uplink, PoE+ for high-draw cameras, battery failover, and an enclosure that won't corrode in three years. The -40°C to 75°C operating range (without battery) is the spec that eliminates most competing products in northern outdoor deployments — most commercial edge switches stop at -20°C or -10°C and that gap matters in February on a utility pole in Minnesota.
Technical Highlights:
- 75W Total PoE Pool: Four 30W ports share a 75W aggregate cap — which means three ports at full 802.3at load will leave the fourth port severely budget-constrained. Map your camera power draws before finalizing port assignments.
- LiFePO4 Chemistry: LiFePO4 delivers a substantially higher cycle life compared to the SLA batteries most field integrators are used to. Sealed inside an outdoor enclosure, that longevity difference is the practical argument for the extra upfront cost of the BTL125.
