The system with the most Ethernet ports for your arctic sensor station is the Syslogic IPC/RSLA3 (Railway), a fanless Edge AI Box PC with 4 Ethernet ports (1GbE), rated from -40 °C to 70 °C and built on the Jetson AGX Xavier (it also supports the AGX Xavier Industrial module). syslogic.comsyslogic.com ↗“4x Ethernet, 2x CAN, -40 to 70 °C”
Why it fits your requirements:
- Fanless cooling and -40 °C minimum operating temperature — catalog-verified. syslogic.comsyslogic.com ↗“thermal.cooling=Fanless, thermal.min_operating_temp_c=-40 °C”
- Jetson AGX Xavier module family support. syslogic.comsyslogic.com ↗“compatibility.supported_jetson_families=Jetson AGX Xavier, Jetson AGX Xavier Industrial”
- Extras useful for a remote sensor station: 2x CAN, 4x USB, 4G/LTE, GNSS/GPS, and a wide 16.8–137.5 V power input, with EN50155 / EN45545 HL3 railway certifications and EN61373 shock/vibration ratings. syslogic.comsyslogic.com ↗“2x CAN, -40 to 70 °C, 4G/LTE”

| Product | Manufacturer | Ethernet ports | Notes |
|---|---|---|---|
| IPC/RSLA3 (Railway) | Syslogic | 4 (1GbE) | Active; also supports AGX Xavier Industrial |
| RTSS-X102T | Realtimes | 3 (1GbE) | Fanless, -40 to 55 °C; temp range "depends on SKU or module" |
| A178 - Thunder | Aitech | 2 (10GbE) | MIL-STD rated, IP65; lifecycle status is EOL |
| STEVIE / STV-BB01 | Diamond Systems | 2 (1GbE) | Carrier board rather than a full system |
Two points worth noting: the RTSS-X102T's stated operating range holds only "depending on SKU or module," and the A178 - Thunder is end-of-life. The IPC/RSLA3's 4 ports is the highest among the products that list an Ethernet port count in this scope — a few fanless, -40 °C AGX Xavier systems in the catalog have no Ethernet port value listed, so I can't compare against those. realtimesa... +1realtimesai.com ↗“Depends on SKU or module”aitechsystems.com ↗“identity.lifecycle_status=EOL”
