The Changfan Tech CF-NANO400 is a fanless industrial PC built for complex network topologies and high edge-computing demands. Compared to the NANO300, it provides up to 4 Intel I226-V Gigabit Ethernet ports and upgraded processor options (up to the 8-core i3-N305). The full-aluminum chassis not only provides highly efficient passive cooling but also offers excellent shock and interference resistance. Whether acting as a complex network node or processing data streams from multiple industrial cameras, the NANO400 delivers a stable and reliable computing platform.

VI. Frequently Asked Questions (FAQ)
Q1: What exactly can the 4 LAN ports of the CF-NANO400 be used for?
A: The 4 ports utilize Intel I226-V Gigabit network chips, known for extreme stability. They can be used for: 1. High-performance soft routers (supporting OpenWrt, iKuai, pfSense, etc.); 2. Enterprise-grade firewall gateways; 3. Edge computing gateways where, for example, 1 port connects to the LAN, 1 to the WAN, and 2 directly to multiple industrial cameras (like Hikvision or Dahua) to achieve multi-subnet isolation.
Q2: I see the processor can be upgraded to an i3-N305. Is this performance sufficient for machine vision inspection?
A: Yes, it is sufficient. The i3-N305 features 8 cores with a 3.8GHz turbo frequency, a qualitative leap over traditional low-power Celerons. For multi-camera acquisition, barcode recognition, dimension measurement, and lightweight AI defect detection algorithms (like YOLO series), combined with its integrated Intel UHD graphics for hardware acceleration, it is fully capable of completing local inference at the edge, significantly reducing the bandwidth cost of transmitting HD video back to a server.
Q3: Factory workshop voltages can be unstable. Does this machine have protection measures?
A: The standard power adapter is 12V DC. If the workshop environment is harsh, you can order the optional 9V-36V Wide Voltage Input Module. This module features overvoltage, undervoltage, overcurrent, and reverse polarity protection. Even if the workshop voltage fluctuates greatly or a 24V industrial power supply is mistakenly connected, the motherboard will not be damaged. Additionally, an optional wide-temperature version (-40°C~70°C) with cold boot support is available.
Q4: If I want to install my own router system or virtual machines, does this machine support it?
A: Absolutely. In addition to standard Windows and Linux, the NANO400's x86 architecture and Intel network cards provide excellent compatibility with virtualization platforms like ESXi and PVE, as well as mainstream soft router systems like pfSense, OpenWrt, and iKuai. If needed, Changfan can pre-install and configure the specified system before leaving the factory.
Q5: The machine has a 4-LAN fanless design. Does it generate a lot of heat under full load?
A: Heat generation is well-controlled. The NANO400 features a heightened finned chassis (163.45 x 126 x 53mm), increasing surface area for better heat dissipation efficiency. Even with all 4 LAN ports forwarding data at full load, power consumption remains very low. The chassis temperature will be slightly higher than room temperature, but it will never crash from overheating, making it far more reliable than fan-cooled devices.
