    • Automated control is provided of rotational velocity of an air-moving device cooling an electronics subsystem of an electronics rack. The automated control includes: automatically responding to a failure event associated with the electronics subsystem of the rack by setting rotational velocity of the air-moving device to a first upper limit (RPM1) above a normal operating limit; sensing motor temperature of a motor of the air-moving device; automatically increasing rotational velocity of the air-moving device to a second upper limit (RPM2) if the sensed motor temperature is below a first predefined temperature threshold (T1), wherein RPM2>RPM 1; maintaining rotational velocity of the air-moving device at the second upper limit while the sensed motor temperature is below a second predefined temperature threshold (T2), wherein T2>T1; and returning to normal operating rotational velocity of the air-moving device subsequent to servicing of the electronics rack responsive to the event.
    • 提供了冷却电子机架的电子子系统的空气移动装置的旋转速度的自动控制。 自动控制包括:通过将空气移动装置的旋转速度设定在高于正常操作极限的第一上限(RPM1)来自动响应与机架的电子子系统相关联的故障事件; 感测气动装置的电机的电机温度; 如果感测到的电动机温度低于第一预定温度阈值(T1),则将空气移动装置的旋转速度自动增加到第二上限(RPM2),其中RPM2> RPM1; 在感测到的电动机温度低于第二预定温度阈值(T2)的同时保持空气移动装置的旋转速度处于第二上限,其中T2> T1; 并且响应于该事件,在对电子机架进行维修之后,返回到空气移动装置的正常操作旋转速度。
