After setting the switches, install the NIM-1W into the
MOM-4/2 card cage. Make sure that the module is in
the card guides and the card edge is firmly seated in the
connectors on the MOM-4/2.
At all times handle all plug-in cards with extreme
care. When inserting or removing a card, be sure the
position of the card is kept at right angles to the
MOM-4 board. Otherwise, the plug-in card can
damage or displace other components.
