The Allnet ALL-NAS355 is a compact industrial mini-PC based on the Intel® N355 Quad-Core processor, designed for use in demanding industrial environments. The device features a robust aluminum alloy housing, precision-machined via CNC, and is suitable for 24/7 operation in network security, control, and automation systems. Passive cooling is supported by a copper heat spreader with aluminum heatsink and a 7010 PWM-controlled fan, ensuring quiet and efficient heat dissipation. The enclosure is available in black or olive green and measures 100 × 100 × 58.5 mm, making it ideal for space-constrained installations.

Applications
The ALL-NAS355 is specifically designed for industrial applications, including network security appliances, firewalls, edge computing, IoT gateways, and automation systems. Its high computing performance combined with low power consumption makes it an ideal solution for continuous, resource-efficient operations. The operating temperature range of –10 °C to +70 °C and humidity range of 5 % to 90 % rF (non-condensing) enable deployment in various climatic conditions, including outdoor environments under appropriate protective conditions.

Features and Specifications in Detail
The device is equipped with an Intel® N355 processor clocked up to 3.5 GHz with 6 MB cache, providing sufficient performance for demanding application scenarios. The memory consists of a 16 GB SO-DIMM DDR5-4800 module, with support for up to 48 GB. Graphics capabilities are handled by Intel® UHD Graphics with up to 32 EUs, enabling simultaneous or asynchronous output to two 4K displays (4096×2160 @ 60 Hz) via HDMI 2.0. For storage, there is an M.2 2280 NVMe slot, which can be expanded to support up to four NVMe interfaces using an adapter card.

Technology Explained Simply
Network connectivity is provided by two Intel® i226-V 2.5 Gbit LAN ports, designed for fast data transfer in networks. USB connectivity includes two USB 3.2 Gen 2 (10 Gbps) ports and two USB 2.0 headers, allowing fast peripheral devices to be connected. Internal interface options include a 10-Pin GPIO (4 inputs/4 outputs), two 4-Pin CPU fan connectors, a COM header, and an Auto-Power-On jumper. Power is supplied via a DC-IN 12 V connector. The BIOS supports features such as PXE boot, WOL (Wake-on-LAN), and GPIO configuration, simplifying integration into networks and automation systems.

Compatibility and Accessories
The ALL-NAS355 is expandable via an M.2 E Key Wi-Fi slot, supporting Wi-Fi 6/7 and optional Bluetooth 5.4. The NVMe quick-release cover with 70×70 mm fan mounting allows for easy maintenance and replacement of storage modules. Installation options include desktop or wall mounting, with dimensions and weight (approx. 1.2 kg) allowing for flexible placement. Power consumption ranges from 6 to 15 W, enabling operation with low energy usage.

Mounting and Installation
Installation is performed using the provided mounting options (desktop or wall mounting). Connectors are clearly labeled and accessible, with the front panel featuring the DC-IN 12 V connector, two 2.5 Gbit LAN ports, two HDMI 2.0 outputs, two USB 3.2 Gen 2 ports, and a power button. Internal headers (GPIO, COM, USB 2.0, SATA) are designed for integration into existing systems. Initial setup is performed using the pre-configured user N901,7 cm ( 355 inch ) and password "welcome.

Operational Advantages
The ALL-NAS355 offers high reliability thanks to its robust aluminum enclosure and passive cooling, ensuring uninterrupted operation in industrial environments. Support for 4K dual-display and fast network and USB connections enables efficient use in applications requiring high data rates and parallel processing. Expandability via M.2 Wi-Fi/Bluetooth modules and support for PXE boot and WOL simplify integration into existing IT infrastructures. The operating temperature range of –10 °C to +70 °C makes the device suitable for deployment in environments with extreme conditions.

Certifications and Applications
The device complies with industrial safety standards and is ideal for network security appliances, firewalls, edge computing, IoT gateways, and automation systems. The combination of compact design, high performance, and low power consumption makes the ALL-NAS355 a versatile solution for industrial IT applications.
