The system detected a room ambient over-temperature warning or fault.

1. Is the room temperature less than 35 degrees C or 95 degrees F?
   • No: Notify the customer. The customer must bring the room temperature within normal range. Continue with the next step.
   • Yes: Continue with the next step.
2. Are the system front and rear doors free of obstructions?
   • No: Notify the customer. The system must be free of obstructions for proper air flow. Continue with the next step.
   • Yes: Continue with the next step.
3. If applicable, do all the positions in the processor subsystem contain processors or fillers?
   • Yes: Continue with the next step.
   • No: Fill any open positions with processors or fillers. This ends the procedure.
4. Do all the power supply positions contain power supplies or fillers?
   • Yes: Continue with the next step.
   • No: Fill any open positions with supplies or fan books. This ends the procedure.
5. Are you working with reference code 7201?
   • Yes: This indicates that the room temperature is too high. The customer must bring the room temperature to less than 35 degrees C or 95 degrees F. If the room temperature is less than 35 degrees C or 95 degrees F, continue with the next step. This ends the procedure.
   • No: Continue with the next step.
6. Perform the following:
   • For model 8204-E8A, exchange the control panel. Use the following table to determine the part number for the field replaceable unit (FRU). Then continue with the next step.

     CCIN or FFC	Type and model	Part number	Description	Location code
     	8204-E8A	42R5505	Operator panel	Un-D1

   • For model 9406-MMA or 9117-MMA, exchange processor 1 and processor 2, one at a time, until either the problem is resolved or you have replaced both processors. Then continue with the next step.

     For each unit, starting with the primary unit and then the secondary units, use the following table to determine the part number for the field replaceable unit (FRU):

     CCIN or FFC	Type and model	Part number	Description	Location code
     	9406-MMA, 9117-MMA	10N9146	3.5 GHz POWER6 - 2 core processor book	Un-P2-C1
     	9406-MMA, 9117-MMA	10N9144	4.2 GHz POWER6 -2 core processor book	Un-P2-C1
     	9406-MMA, 9117-MMA	10N9139	4.7 GHz POWER6 -2 core processor card	Un-P2-C1

7. After each FRU is exchanged, is the error code that sent you to this procedure still reported?
   • No: The problem has been corrected. This ends the procedure.
   • Yes: Replace the next FRU on the list. If all FRUs on the list have been replaced, call your next level of support. This ends the procedure.
