Over- temperature Failures

A temperature sensor mounted on the array’s controller board signals over- temperature status. Each status is triggered at a different temperature.

Indicators

•Display/operation:$51:$51,1*panel displays one of the following messages:

7(03&5,7&5,7,&$(user/-definable, 45 degrees C default) (standard: 50 degrees C)

•Audible alarm sounds (if enabled).

•	If 7(03	displays, all drives will be spun down (if enabled).
Handling

Table 6: Array Temperature

If the array’s temperature exceeds either the :$51,1*or &5,7,&$/ threshold, the alarm sounds and the appropriate message appears on the display/ operation panel. Both the alarm and the display message will remain until you touch a key on the panel (the up-arrow key is preferred to clear the alarm because it will not clear the error display).

Even if the temperature has gone below both over-temperature thresholds, this setup ensures that you will be aware of an over-temperature situation, even if the temperature returned to normal before you could intervene. When the alarm and display message have been cleared, you can determine the array’s current temperature by invoking the 7(036(16256command in the display/ operation panel $55$<,1)2menu.
