Install the COM Express assembly into the chassis
1. Prepare a chassis designed to accept a standard FlexATX‐sized board.
2. Remove any I/O shielding included with the chassis, and replace it with the CR100 carrier
board's I/O shielding from RadiSys.
3. Fit the module and carrier board assembly into the chassis and snap the carrier board's rear
I/O panel into the I/O shielding.
Note: To avoid electromagnetic interference, ensure that the springs on the I/O shielding are
in full contact with the CR100 carrier board's rear I/O panel.
4. Use the screws and standoffs supplied with the chassis to mount the carrier board. Torque
values vary according to the size and material of the screws used. Check with your chassis
manufacturer for the recommended torque values of any screws they provide.
