Installing SODIMM memory
on COMe-9X90 module
Step 1
Align the notch on the memory module with the protruding wedge on the
SODIMM slot. Insert the memory module into the slot at 30 degrees angle.
Installing COMe-9X90 module
to COMEDB4 carrier board
Step 6
Connect the CPU fan connector cable.
Step 1
Locate the carrier board mounting points (x5) and the connectors (x2).
Step 5
Install the heatsink on COMe-9X90 module. Secure it with four M2.5x15mm
screws (with 3mm plastic washer).
1
Step 3
Align the pin connectors and mounting points of the COMe-9X90 module
into the connectors and hex spacers on the carrier board respectively. Then
press down the COMe-9X90 module until the pin connectors have been
fully inserted into the connectors.
Onboard Pin headers and Connectors
Step 2
Push down until the memory module snaps into place. The memory slot has
two locking mechanisms that will click once the memory module has been
fully inserted.
