Installing heatsink with fan
1
Step 1
Align the heatsink over the heatsink mounting hole on the COMe-8X91.
Installing COMe-8X91 module
on the COMEDB3 carrier board
2
Step 2
Install the hex spacers onto the carrier board. The hex spacers will be
placed on top of the board. From the bottom of the board, tighten the
hex spacers by using the M2.5*4 screws.
Step 1
Identify the carrier board mounting points and the connectors slots.
Step 4
Secure the COMe-8X91 module with the heatsink by screwing and
tightening the four screws (10mm screws).
Step 3
Align the connector of the COMe-8X91 module into the connector slot on
the COMEDB3 carrier board. Also, align the mounting points of COMe-
8X91 module into the hex spacers on the carrier board.
