3. Install the Reed-Solomon PCB to the interface PCB. Mate the male header
connectors JP2, JP3, and JP1 on the Reed-Solomon PCB with the interface PCB
female header connectors J2, J3, and J4, respectively. Refer to Figure A-5 for the
connector and mounting hardware locations.
4. Align Reed-Solomon PCB standoffs with the interface PCB mounting holes.
Install the six mounting screws and washers.
CAUTION
The mounting hardware must be installed to provide proper
grounding between the Reed-Solomon PCB and the interface PCB.
5. Re-install interface PCB to the modem.
6. After completing the above installation procedure, turn on the modem.
