A Storage Administrator notices two fans in a Dell PowerStore are faulted.

A five-minute timer starts upon the second fan fault and the system shuts down automatically after the timer expires

CPU clock speed is reduced by 50% to lower internal temperatures and the system continues normal operations

An increased fan speed signal is sent to the surviving fans and the system continues normal operations

Upon the second fan fault, all host I/O is terminated immediately and the PowerStore goes through the halt and vault process and shuts down
