screws located in the back of the CommPlete 4000. See figure 4-3.
3 Remove the two chassis mounting screws from the card cage. See figure 4-4.
4 Being careful to maintain slack in the power cables, lift the card cage up and over so
that it rests along side the chassis.
5 Remove screws that secure the serial card to the chassis at the back of the CommPlete 4000 .
