Usage Features
Quick Start Guide:
To use the fitlet3, RAM and a storage device are required (if not pre-installed). A display with HDMI or DisplayPort input, an HDMI or mini-DisplayPort cable, and a USB keyboard and mouse are also necessary. The specific configuration of the fitlet3 is detailed on a label attached to the bottom side of the computer. If RAM and storage are not installed, the fitlet3 will not boot.
Opening the Device:
To install RAM, storage, and the RTC battery, the fitlet3 needs to be opened. This requires a Phillips screwdriver.
- Place the fitlet3 bottom-up on a flat surface.
- Unscrew the four screws counter-clockwise.
- Lift the bottom cover to remove it; side panels should fall off.
- Lift the fitlet3 from the top cover.
Installing RAM:
The RAM socket is on the top side of the motherboard. The fitlet3 accepts a single SODIMM DDR4 module. Insert the DDR4 SODIMM module and press it down until it latches firmly on both sides.
Installing M.2 Cooling Plate, SSD, and Modem:
The M.2 cooling plate serves multiple purposes: allowing installation of various M.2 devices, providing cooling, assisting in battery placement, and managing cables.
- M.2 Key-M supports SATA of NVME modules (2230, 2242, 2260, or 2280).
- M.2 Key-B supports SATA M.2 modules or modems (30mm, 42mm, 52mm, or 60mm lengths; 22mm or 30mm widths).
The SSD must be fastened to the M.2 cooling plate, which is then placed on the underside of the motherboard and fastened to the front and back panel.
- Peel off the protective film from the two thermal pads.
- Place the red M.2 spacer according to the length of the M.2 SSD, ensuring the recessed side faces the alignment screws. Insert the M.2 fastening screw but do not tighten yet.
- Place the edge of the M.2 SSD against the fastening screw. Press the SSD firmly against the thermal pad until its connector edge is seated between the alignment pins. The connector edge should protrude above the M.2 cooling plate.
- Tighten the fastening screw.
- Turn over the M.2 cooling plate and push the M.2 SSD into its socket at the underside of the motherboard.
- Push down the M.2 cooling plate and tighten the 3 panel screws.
Installing Optional WiFi/BT Module:
By default, the WiFi/BT module is not installed.
- Assemble the adapter.
- Tighten the appropriate screws.
- Insert the red spacer and fastening screw, but do not tighten it.
- Insert the WiFi/BT module into the appropriate socket at an angle.
- Press it down until it latches the spacer.
- Tighten the fastening screw.
Installing RTC Battery:
The RTC battery maintains time and date when the fitlet3 is disconnected from power. It is typically shipped unplugged to prevent discharge during warehousing.
- Connect the battery plug to the corresponding socket.
- Route the wire through the slots of the M.2 cooling plate to minimize clutter.
- Place the battery in the marked pocket; it will be secured once the bottom cover is assembled.
Re-assembling the Device:
- Place the fitlet3 onto the top cover (it is symmetric, so direction does not matter).
- Place the bottom cover onto the fitlet3. Ensure the tall U-shaped boss is near the M.2 sockets; otherwise, the bottom cover will not fit.
- Click both side panels into place.
- Tighten the 4 screws.
Connecting the Device:
- Ensure RAM and storage are installed.
- Connect the display using an HDMI or mini-DP cable.
- Connect a USB keyboard and mouse.
- Insert the DC plug into the fitlet3 DC-in jack.
- Rotate the DC plug clockwise 90° to secure.
- Attach the correct AC blade to the power supply and plug it into an AC outlet. The power button LED should turn green, and an image should appear on the display shortly.
- Connect an Ethernet cable as needed; the link LED on RJ45 should light up.
- If a WiFi adapter is installed, connect the included antennas by screwing them clockwise onto the SMA connectors on the side panel.
Entering BIOS Setup:
- Turn off the fitlet3.
- Turn it on while holding down the Del key to access the AMI Inc. BIOS utility.
Installing and Booting Operating System:
Refer to the official website for detailed instructions on installing and booting an operating system.
Maintenance Features
Safety Instructions:
- Disconnect all power sources before opening the computer cover or panels.
- Only certified service technicians should perform repairs.
- Avoid electrostatic discharge by handling components and cards with care.
- When disconnecting a cable, pull on its connector or pull-tab, not on the cable itself.
