3. Setup Guide

3.1 Unboxing and Initial Inspection

Carefully remove all components from the packaging. Verify that the following items are included:

• CWWK X86-P5 Mini PC
• Power Adapter (12V DC)
• USB 7015 Fan (optional, for additional cooling)
• Fan Cover
• NVMe SSD Thermal Pads
• Screws

3.2 Hardware Installation (RAM and SSD)

The device may come with pre-installed RAM and SSD, or as a barebones unit. Follow these steps for installation or upgrade:

1. Accessing Internals: The top cover of the aluminum casing is freely removable. Gently lift or slide it off to expose the internal components. Refer to Figure 5 for an exploded view of the product structure.
2. RAM Installation: Locate the single SO-DIMM DDR5 slot. Insert the RAM module firmly until the clips on both sides snap into place.
3. NVMe SSD Installation: Identify the four M.2 2280 NVMe slots. Insert your NVMe SSDs into the slots at an angle, then gently push down and secure with the provided screws. Apply thermal pads to the SSDs before securing the top cover for optimal heat dissipation.
4. Optional WiFi/BT Module: If expanding with a wireless card, locate the M.2 E-Key slot. Insert the WiFi/BT module and connect any necessary antenna cables (antennas typically sold separately). Refer to Figure 6.
