Action
Replace the system board and chassis assembly, as described in
"Replacing the FRU system-board and chassis assembly" on page 264.
1. Measure the ambient room temperature to see if it is in within the
upper limit of the normal operating range. The upper limit is less than
35 degrees C or 95 degrees F. If the temperature exceeds this limit, you
must bring down the room temperature until it is within the limit.
When the temperature is within range, retry the operation.
2. If the temperature is within the acceptable range, check the front and
rear of the BladeCenter unit to verify that the each is free of
obstructions that would impede the airflow. If there are obstructions,
you must clear the obstructions. Also clean the air inlets and exits in
the BladeCenter unit drawer as required. If you cleared obstructions,
retry the operation.
3. Verify that the fans in the BladeCenter unit are working correctly. If
not, replace fans that are not turning or that are turning slowly. If you
replace fans, wait for the unit to cool and retry the operation.
4. If the cooling components are functioning correctly, replace the system
board and chassis assembly, as described in "Replacing the FRU
system-board and chassis assembly" on page 264.
