Safety & Compliance

The aluminum enclosure acts as a heatsink and may reach high temperatures during sustained workloads. Avoid touching the top cooling surface during extended operation or immediately after shutdown.

The device is rated IP40. Keep it away from liquids, condensation, and flammable materials. Direct outdoor exposure requires a separate protective enclosure.

Apply standard ESD precautions (wrist strap, grounded mat) when handling the device with the enclosure open or working near exposed connector pins.

The ALPON X4 contains no user-serviceable parts. Opening the enclosure voids the warranty. Contact Sixfab support for any internal repair or modification.

Do not insert metal or conductive objects into ports, vents, or connectors. Avoid impact damage to the aluminum housing and antenna connectors.

Use only one power input at a time. Disconnect the existing source before connecting another; do not use multiple connected sources as a redundancy or failover arrangement.

Typical consumption is 7–14 W with a 27 W system peak. Optional PoE+ delivers up to 25 W and cannot cover that simultaneous peak. Reduce peripheral load or use a supported DC/USB-C PD supply for peak workloads. Do not infer any particular overload or automatic load-shedding behavior.

PoE+ is available only on variants that include the built-in PoE module. The module cannot be added in the field. Use a PoE+ (IEEE 802.3at) Class 4 injector or switch supplying 37 to 57 V; legacy PoE (802.3af) cannot deliver enough power for the ALPON X4.

ETH/G carries Gigabit Ethernet data and, on PoE variants, PoE+ power input. The 100 Mbps ETH port is data-only. Neither port supplies PoE power to another device.

Use the included USB-C PD adapter or a compatible source providing the documented 15 V at 1.8 A (27 W) profile.

Standard 5 V USB-C chargers and PC USB ports are not supported for normal operation. The USB-C port requires a USB-PD-capable source negotiating 15 V.

The USB-C port is sink-only for power. Use USB Type-A for normal data peripherals. Recovery or flashing access must follow model-specific Sixfab instructions; do not infer a recovery procedure from the connector shape.

Non-compliant USB-C cables can drop voltage under sustained load even with a capable adapter. If consumption approaches 27 W, swap cables for ones rated above the minimum.

Keep the device away from direct heat sources (ovens, motors, boilers) and steam. Radiant heat reduces ambient headroom against the +60 °C operating limit.

Keep airflow around the cooling surface unobstructed and verify cabinet ventilation against the combined heat load. Consult Power & Mounting and Sixfab for verified mechanical clearance guidance; no numeric certified minimum is established here.

Two 4 mm mounting holes on the rear of the enclosure support DIN rail or wall mounting with the appropriate accessories. Ensure mounting hardware does not contact the cooling surface.

Never install, remove, or service antennas while the device is powered on. Disconnect every power source first to prevent electric shock and RF transmitter damage.

Hand-tighten antenna connectors without forcing or over-tightening them. Use a torque tool only with connector-specific limits confirmed by Sixfab or the antenna manufacturer.

Inspect connectors for corrosion, debris, or damage before each reattachment. Replace compromised connectors rather than forcing a fit.

For outdoor or harsh environments, use the optional 3-meter cabled IP67 combination antenna with surface mount instead of the bundled stub antennas.

Do not swap antennas between ports. LTE, Wi-Fi, and GNSS ports are tuned for different frequency bands; mismatched antennas degrade link quality and may overload the RF front-end.

Keep antennas clear of metal surfaces, reinforced concrete, and other sources of electromagnetic interference such as microwave ovens, cordless phones, and large motors.

The GNSS antenna must be placed in an open area with the top facing the sky. Obstructed or ground-level placement degrades time-to-first-fix and position accuracy.

When attaching high-draw USB peripherals (SSDs, cellular dongles, external hubs), budget current across both ports together, not per port.

For USB peripherals that exceed the on-device budget, use a powered USB hub with its own external supply.

Watchdog DIP. When enabled (SW1 OFF), the host must supply the documented watchdog heartbeat or the device resets. Assign one heartbeat owner: the system daemon or an application configured to replace it, never both. Disable the watchdog (SW1 ON) for controlled servicing only, with power disconnected before changing the switch.

Boot/Burn DIP. SW2 OFF is normal Boot mode; SW2 ON is Burn mode. Change it only with all power disconnected and only as directed by the supported recovery procedure. Contact Sixfab before flashing if the model-specific host connection and recovery image are not confirmed.

Do not dispose of the device in unsorted household waste. Return it through an authorized WEEE collection point, a local electronics recycler, or back to Sixfab for responsible processing.

The ALPON X4 contains a CR1220 coin-cell battery for the real-time clock. The battery is accessible only through authorized service and must be disposed of separately at end-of-life.

Before disposal or return, erase sensitive data from the eMMC and any connected storage. Retain the original packaging for return shipping.
