 CAUTION 

Ensure that proper airflow is maintained in the processor voltage regulator circuit.  Failure to do 
so may result in damage to the voltage regulator circuit.  The processor voltage regulator area 
(item A in Figure 24) can reach a temperature of up to 85 

o

C in an open chassis. 

Figure 24 shows the locations of the localized high temperature zones.
