4. Set the function switches on the FM250 module. (See Page 10)
5. Carefully and slowly guide the module into the slot with the PCB components facing to the right. Note: The module heatsink
top and bottom metal edge mate with the mainframe plastic card guides. Do not force the card. Realign if necessary.
6. After the module is pushed in and in contact with the back plane of the PCB assembly mating connector, firmly press the
module in completing the connection. If the module plate is flush to the F6-MF, the module is fully seated.
