a. The 10-conductor cable from the daughtercard on the I/O card (800252)
assembly.

the middle of the card directly below the 10-conductor ribbon cable.
c. The 26-conductor cable from the RDC card (800225) assembly going into
the middle of the card directly below the previous cable.

screen will indicate some alarm conditions because of the
disconnected cables.
10. On the rear of the 7200 ACU, set the power switch to the on position. If
desired, acknowledge any faults.

arrow points to position 4.

15. On the 7200 ACU rear panel, set the power switch to the off position for 5
seconds and then set the power switch to the on position.
