Instructions
Align the 2 holes on part onto the U-shape area of the .
Take 2 of to tighten into the to secure the part
Take the and align the 4 holes on each corner to the holes on part . Make sure that the fan pushes air downwards through the U-shape hole on the as indicated by the arrow on the fan (refer to the image below for a clearer look).
Take 4 of and secure the to part .
Grab the with the Ethernet RJ45 port facing away from you.
Take the out of the package and lightly place it into the corresponding pins of the in the orientation shown below in the images and visualization.
Evenly press down on the left, right and bottom of the till the module slides into place. Apply pressure evenly to ensure all pins have an even contact with the .
It should make a "click" sound once it sit in place correctly. Watch the video below for more instruction.
Align the with the via the 2.54 mm pins, pressing down gently till the connectors are in full contact. Refer to the visualization below to install the two boards together.
Prepare the power connection for the fan by connecting it to a 4-pin JST-XH cable using Wago as shown in the image below.
Connect the fan wire to the 2 center wires of the cable (You should be able to see in the image what the white cable only has 2 middle wire instead of all 4 wires, the 2 wires on each end has been cut and not used). You could also solder the wire, if you prefer a cleaner solution.
