Dell PowerStore Planning Guide

If the system exceeds the maximum ambient temperature by approximately 10°C (18°F), the nodes in the system begin an orderly shutdown that saves cached data, and then shut themselves down. Link control cards (LCCs) in each expansion enclosure in the system power down drives but remain powered on.

If the system detects that the temperature has dropped to an acceptable level, it restores power to the base enclosures and the LCCs restore power to their drives.
