System Setup

This chapter provides information on setting up the ALDERAMIN MK3 Embedded System hardware.

	Warning: The edge of the ALDERAMIN MK3 aluminum extrusion fins is sharp. Please be careful when moving the unit, installing it, and operating the embedded system!

2.5” SATA HDD/SSD Installation

Follow the instructions below to install a SATA HDD:

• Remove the door from the front bezel.

Note: After loosening the four screws from the expansion door, gently lift the cover with your fingernail and carefully remove the door from the front bezel.

• Pull the HDD tray out from the main chassis.

• Fasten the screws to secure the HDD/SSD to the bracket.

• Insert the HDD/SSD tray back into the main chassis and fasten the screws on the door.

Note: Keep the unit horizontal to make it easier to insert the HDD tray back into the machine.

2nd and 3rd 2.5” SATA HDD/SSD Installation

• Remove the GND screws from the rear bezel.

• Remove the bottom cover.

• Loosen the four HDD bracket screws and pull the bracket out of the unit.

• Secure the 2nd and 3rd HDD/SSD to the bracket as shown in the concept drawing.

• Fasten the four bracket screws to the main unit.

• Follow the drawing to route the SATA cables.

CPU/CPU Heatsink/DRAM Installation

• Remove the GND screws from the rear bezel.

• Remove the bottom cover.

• Loosen the four M4 screws from the main chassis.

• Ensure that the two GND screws are loosened, then pull the main chassis from the aluminum extrusion. There are chipset thermal pads (L6) and two guide pins on the aluminum extrusion, so you will need to apply force to pull it out.

Warning: Be very careful of the sharp edges of the aluminum and metal parts when pulling the main chassis out.

• Take the CPU passive cooler from the accessories and install the CPU, CPU heatsink, and DRAM modules as shown in the picture.

RTC Battery Maintenance

• Preparation for disassembly:

Flathead Screwdriver (The battery holder is designed for high vibration resistance and harsh environments, so a tool is needed to disassemble the coin battery)

• Insert the flathead screwdriver into the gap on one side of the RTC battery vertically.

• Rotate the screwdriver about 45 degrees to loosen the coin battery.

External Fan (Optional) Installation Guide

• Twist the thumbscrews counterclockwise on the external fan.

• Align the edge of the external fan bracket with the green arrows, and align the metal latch with the red arrow direction. Then insert the fan into the center of the housing.

• Tighten the thumbscrews to secure the external fan and connect the 4-pin cable to the PWM fan connector on the rear I/O.

Note: Do not operate the system when it is powered on. Improper installation of the external system fan bracket with the system powered on may cause injury.
