b. Remove one of the AMDs from the system that was not previously removed during thisprocedure. (Disregard an AMD SRC if it occurs during this step.)c. Power on the system.Does a power reference code occur?v Yes: Have you removed all of the AMDs one at a time?– No: Continue with the next step.– Yes: Install all the AMDs and continue with step 8 (See page 168).v No: The AMD that you removed in this step is the failing item.This ends the procedure.7. Perform the following:a. Power off the system.b. Install the AMD that was removed in step 6 (See page 167) in the original location.c. Go to step 6b (See page 168).8. Replace the following one at a time:v V/S communication cable (SIG72) CB1 to CEC enclosure.v Network Interface Controller/Clock Card M06.v Processor backplane location MB1 (see symbolic FRU “SYSBKPL” on page 464 ), and processor(location M03 or M04).This ends the procedure.9. Perform the following:a. Reinstall one of the cards that you removed in step 2 (See page 167), in the following order:v M01v M02v M05b. Reconnect the ac power cable to the unit that you are working on.c. Power on the system.Does a power reference code occur?v No: Continue with the next step.v Yes: Exchange the last card that you reinstalled in this step.This ends the procedure.10. Have you reconnected all the cards?v Yes: Replace the following one at a time:– V/S communication cable (SIG72) CB1 to CEC enclosure.– Network Interface Controller/Clock Card M06.– Processor backplane location MB1 (see symbolic FRU “SYSBKPL” on page 464 ), andprocessor (location M03 or M04).This ends the procedure.11. No: Repeat step 9 (See page 168), reinstalling next card.Power PIP8: For use by authorized service providers.A power supply fault or load fault has occurred in a FC 5078, FC 0578, FC 5088, or FC 0588.
