Blower modules

The BladeCenter unit comes with two hot-swap blower modules for cooling
redundancy. The blower speeds vary depending on the ambient air temperature at
the front of the BladeCenter unit and the temperature of internal BladeCenter
components. If the ambient temperature is 22°C (72°F) or below, the BladeCenter
unit blowers will run at 30% of their maximum rotational speed, increasing their
speed as required to control internal BladeCenter temperature. If the ambient
temperature is above 22°C (72°F), the blowers will run at 80% of their maximum
rotational speed, increasing their speed as required to control the internal
BladeCenter unit temperature. If a blower fails, the remaining blower continues to
cool the BladeCenter unit and blade servers. Replace a failed blower as soon as
possible, to restore cooling redundancy. See the Hardware Maintenance Manual
and Troubleshooting Guide for instructions.
