%May 14 21:37:35:713 2010 H3C DEV/4/BOARD TEMP TOOHIGH:
Board temperature is too high on Frame 0 Slot 0, type is MPU.
The output shows that the temperature inside the router has exceeded the upper threshold 75°C (167°F).
In this case, the fans of the router will rotate at full speed.
Generally, after the fans rotate at full speed for a certain period, the temperature inside the router will
drop below 75°C (167°F), and the following information appears on the configuration terminal:
