When the warning levels are reached an AutoSupport will be generated and if the critical levels are reached the storage system will shutdown. Sensor 1 is in the shelf, sensor 2 is in the A module and Sensor 3 is in the B module. If the warning threshold is reached, a warning AutoSupport is generated and if the critical threshold is reached on a shelf it will not power off.
