The M.2 cooling plate has several purposes:

• Allow installation of multiple form factor M.2 devices and FACET Cards

• Provide cooling to M.2 devices

• Assist in battery placement

• Provide proper cable management inside fitlet2RC

fitlet2RC accepts M.2 M-key 2242 | 2260 SATA SSD.
The SSD has to be fastened to the M.2 cooling plate. Then the M.2 cooling plate is placed at the
underside of the motherboard and fastened to the front and back panel.

To install SSD onto M.2 cooling plate

1. Screw the 3 alignment screws into the marked holes. These screws are used to position the

M.2 devices

2. Peel-off protective film from the two thermal pads.

3. Place the red M.2 spacer according to the length of the M.2 SSD as depicted below.

Note orientation of the spacer: The recessed side should face the alignment screws.

RTC battery

The RTC battery is used for keeping time and date while fitlet2RC is disconnected from power.
BIOS settings and power-up policy is independent of battery. fitlet2RC normally ships with the
battery unplugged to ensure that the battery is not discharged during warehousing.
The battery can keep charge for approx. 5 years when fitlet2RC is disconnected and
significantly longer when fitlet2RC is connected to power. Battery can be purchased separately
to be replaced by the user.

Installing RTC battery

1. Connect the battery plug to the corresponding socket (see illustration).

2. Place the wire as shown inside the slots of the M.2 cooling plate to minimize clutter.

3. Place the battery in the marked pocket. Once fitlet2RC bottom cover is assembled the

battery is secured in place.
