Altronix NETWAY4E1BTPL3 4-Port Hardened 802.3bt PoE Switch with SFP and Battery Backup

Overview

The Altronix NETWAY4E1BTPL3 is a hardened 4-port 802.3bt PoE switch and power supply/charger in backplane form — built specifically for deploying high-draw IP devices at remote or edge locations where a standard PoE switch would fall short on power budget. With 90W available per port and 360W total output, it handles the latest generation of Altronix NetWay Spectrum-based fiber-to-PoE infrastructure as well as any 802.3bt device on the market today. A single 1Gb SFP uplink lets the unit pull data from a fiber head-end over single-mode or multi-mode runs, eliminating copper distance limits at the field edge.

The NETWAY4E1BTPL3 ships as a backplane module, meaning it drops into a compatible enclosure or rack tray rather than standing alone — keep that in mind during your BOM review. It carries CE, TAA, NDAA, and BAA compliance listings, making it viable for federal and defense-adjacent deployments where those certifications matter at the device level.

Key Features

• 90W Per Port / 360W Total Budget: IEEE 802.3bt (4PPoE) support means you're not rationing power across ports. Pan-tilt-zoom cameras with built-in heaters, multi-sensor heads, door controllers with strikes, and access readers with displays can all run simultaneously without throttling. At full 360W draw on a 115VAC feed, the input fuse is rated 5A/250V — size your branch circuit accordingly.
• 1Gb SFP Uplink: The single Gigabit SFP port accepts Altronix P1MM (multi-mode), P1SM10 (single-mode), or P1GCE (copper) transceivers, giving you flexibility to match the fiber type already pulled in the building. This is the path back to the NetWay Spectrum head-end; the PoE ports handle last-drop to devices.
• Hardened Operating Range Down to -40°C: At full 360W load, the unit is rated -40°C to 45°C — genuinely useful for unheated telecom closets, parking structure equipment boxes, and outdoor-adjacent installs where ambient isn't controlled. Reduce your load budget and the upper limit climbs: at 180W it operates to 65°C.
• 48VDC Battery Backup with Instantaneous Failover: The integrated 48VDC charging circuit supports sealed lead-acid or gel batteries (sold separately, in a separate ventilated enclosure). On AC loss, failover is instantaneous with no transition gap — critical for access control points and video analytics nodes that can't tolerate a reboot cycle during a power event.
• IEEE 802.3af/at/bt All Supported: Auto-negotiation across all three PoE standards means you can mix 15W cameras alongside 90W PTZs on the same switch without manual power class configuration. The per-port PoE On LEDs and per-port IP link/speed LEDs make field verification straightforward without a laptop.
• NDAA and TAA Compliant: Both compliance listings are documented on the manufacturer product page for this SKU — not a family-level claim. TAA compliance satisfies GSA Schedule purchasing requirements; NDAA Section 889 compliance blocks the banned-entity list for federal video surveillance procurement.
• Auto-Crossover RJ45 on All Four Ethernet Ports: 10/100/1000 Mbps with auto MDI/MDI-X means no crossover cable headaches during installation. CAT5e minimum is required; use CAT6 or better if you're running near the 90W heat threshold on longer runs.
• 183 BTU/Hr Thermal Output: At full load, plan for roughly 53W of heat dissipation. In a sealed backplane enclosure this matters — verify your enclosure's thermal rating accommodates that load before commissioning at max power.

Integration and Compatibility

The NETWAY4E1BTPL3 is designed to operate within Altronix's PoE switch and power NetWay Spectrum ecosystem. The SFP uplink interfaces with NetWay Spectrum head-end media converters and injectors using standard Altronix SFP transceivers (P1MM, P1SM10, P1AB2K kit, or P1GCE copper). The NetWaySP1A PoE-powered fiber media converter/repeater is a complementary device when you need to extend a PoE segment further down a fiber run.

Because this is a backplane variant, it is not the same unit as the NEMA4/4X IP66-rated outdoor models (NetWay4E1BTWPX3 and NetWay4E1BTWP3) or the NEMA1 indoor enclosure version (NetWay4E1BTX3). If your installation requires a self-contained weatherproof enclosure, select the WP or WPX variant. The NETWAY4E1BTPL3 assumes the integrator is providing the enclosure separately.

For NVR and recording deployments where you're aggregating multiple PoE edge switches back to a central recorder, pair this unit with a managed uplink switch that can handle the 1Gb SFP fiber feed. The unit does not have management interfaces — it operates as an unmanaged switch, so VLAN segmentation and QoS must be handled upstream.

When to Choose a Different Model

If your install needs an integrated weatherproof enclosure — for example, a rooftop junction box or exterior wall mount — look at the NetWay4E1BTWP3 (NEMA4/4X, IP66) or the NetWay4E1BTWPX3 which adds battery capacity for up to four 12VDC/4AH cells. The backplane format of the NETWAY4E1BTPL3 is the right pick only when you control the enclosure separately or are populating a larger chassis. If your per-port power requirement is below 30W across all ports, a standard 802.3at (PoE+) switch saves cost and runs cooler in confined spaces.

Frequently Asked Questions

Q: Is the NETWAY4E1BTPL3 NDAA Section 889 compliant?

A: Yes. The NETWAY4E1BTPL3 carries a documented NDAA compliant listing on the manufacturer's product page, along with CE, TAA, and BAA compliance. These are SKU-level listings, not family-level claims.

Q: Does the NETWAY4E1BTPL3 include its own enclosure?

A: No. The NETWAY4E1BTPL3 is the backplane version of Altronix's 4-port 802.3bt switch. It requires a separate enclosure. If you need a self-contained unit with an IP66-rated outdoor housing, select the NetWay4E1BTWP3 or NetWay4E1BTWPX3 variants instead.

Q: What batteries are compatible with the NETWAY4E1BTPL3 backup charging circuit?

A: The unit accepts sealed lead-acid or gel type batteries charged at 48VDC. Batteries are sold separately and must be housed in a separate ventilated enclosure per the manufacturer's installation requirements.

Q: What SFP transceivers work with the NETWAY4E1BTPL3?

A: Altronix lists four compatible SFP modules: P1MM (multi-mode), P1SM10 (single-mode), P1AB2K (single-mode kit), and P1GCE (copper). These cover multi-mode fiber, single-mode fiber, and copper uplink scenarios.

Q: What is the warranty on the NETWAY4E1BTPL3?

A: Altronix offers a Lifetime Warranty on this product, as listed on the manufacturer's product page.

Q: Can the NETWAY4E1BTPL3 operate in cold environments?

A: Yes. At full 360W load, the operating temperature range is -40°C to 45°C (-40°F to 113°F). If you run at reduced power loads (180W or less), the upper temperature ceiling increases — up to 65°C at 180W — which can be useful in warmer equipment spaces.

The NETWAY4E1BTPL3 is the unit I reach for when I need 802.3bt power at a fiber-fed remote node and the integrator is supplying their own enclosure. The 90W-per-port budget at full 360W total is the spec that changes what's deployable at the field edge — you're not picking cameras or access controllers based on what the switch can power, you're picking them based on what the job requires.

Technical Highlights:

• 360W Total / 90W Per Port: All four ports can simultaneously deliver 802.3bt Class 8 (90W) without derating — no hidden power sharing table. That's the headroom needed for high-wattage PTZs with integrated IR illuminators, heated multi-sensor units, and access control panels with electric strike loads on the same switch.
• Instantaneous Battery Failover at 48VDC: The charging circuit and failover logic are internal — no external UPS module needed. On AC loss, the switch and all PoE loads stay live without a reboot. Pair sealed lead-acid cells in a ventilated enclosure at the same location and you have a true edge UPS for a fraction of the cost of an external unit.
• -40°C Cold-Start at Full Load: Most unmanaged PoE switches bottom out at 0°C or -10°C. This unit's -40°C lower limit at full 360W draw makes it genuinely usable in unheated northern installations, parking structure junction boxes, and transportation infrastructure where HVAC isn't available at the cabinet.

Deployment Considerations:

• This is a backplane module — it has no enclosure of its own. Confirm your rack chassis or cabinet tray is compatible before ordering. If you need a turnkey weatherproof unit, the NetWay4E1BTWP3 (NEMA4/4X, IP66) is the correct variant.
• At full 360W output the unit dissipates approximately 183 BTU/Hr. In a sealed backplane enclosure without active cooling, that thermal load can push ambient above the 45°C ceiling faster than expected. Size your enclosure ventilation before commissioning at max power draw.

The NETWAY4E1BTPL3 is best positioned for fiber-backbone campus deployments — think university perimeter nodes, transit authority camera poles, or hospital campus outbuildings — where you need 802.3bt power at the leaf, a clean 1Gb fiber uplink back to the head-end, and battery-backed failover at each remote location without running a separate UPS.
