| Spec | Lanner EAI-I351 | JWIPC W638 |
|---|---|---|
| Max Ethernet speed | 25GbE (1 Ethernet port) | 10GbE (2 Ethernet ports) |
| Cooling / thermal | Fan-cooled, –25 °C to 50 °C operating | Fan-cooled, –20 °C to 40 °C operating |
| Power input | 24–48 VDC | 24 VDC only (200 W max consumption) |

Summary of the trade-offs:
- Ethernet: The EAI-I351's single port runs at up to 25GbE, faster than the W638's 2× 10GbE — the W638 gives you more ports, but lower per-port ceiling. lannerinc... +1lannerinc.com ↗“io.max_ethernet_speed=25GbE”jwipc.com ↗“io.max_ethernet_speed=10GbE, io.ethernet_ports=2”
- Cooling: Both use active fans, but the EAI-I351 supports a wider temperature range (–25 °C to 50 °C vs. –20 °C to 40 °C), giving more headroom in hotter or outdoor-adjacent deployments. lannerinc... +1lannerinc.com ↗“thermal.cooling=Fan, thermal.max_operating_temp_c=50 °C, thermal.min_operating_temp_c=-25 °C”jwipc.com ↗“thermal.cooling=Fan, thermal.max_operating_temp_c=40 °C, thermal.min_operating_temp_c=-20 °C”
- Input voltage: The EAI-I351 accepts 24–48 VDC, more flexible for industrial battery/plant power supplies; the W638 is 24 VDC only, though it draws up to 200 W. lannerinc... +1lannerinc.com ↗“power.power_input=24-48 V”jwipc.com ↗“power.power_input=24-24 V, power.max_power_consumption_w=200 W”
