Features
For fan group 1, when all appropriate temperature sensors register temperatures of 50 degrees C or lower, group 1 fans run at 60% of maximum speed. If firmware detects any sensor reading (on the baseboard or any IOM) above 50 degrees C, all group 1 fans will increase to 100% of maximum speed. In addition, if firmware detects a failure of any fan in group 1, all other group 1 fans will be increased to 100% of maximum speed.
For fan group 2, behavior is similar. When all appropriate temperature sensors register temperatures of 50 degrees C or lower, group 1 fans run at 60% of maximum speed. If firmware detects any sensor reading (on the rear of the baseboard or any power supply sensor) above 50 degrees C, all group 2 and 3 fans will increase to 100% of maximum speed. In addition, if firmware detects a failure of any fan in group 2 or 3, all other group 2 and 3 fans will be increased to 100% of maximum speed.
