SMART Thermal Shutdown

Does my enclosure support this feature? See Supported Features.

Enclosure management provides a feature which automatically shuts down the operating system and

turns off the server and enclosure, when the temperature of the enclosure drops below the minimum

threshold value or exceeds the maximum threshold value. The temperature, when shutdown occurs, is

determined by the Minimum Failure Threshold and the Maximum Failure Threshold value. These

thresholds are default settings that cannot be changed.

NOTE: Thermal shutdown does not apply to the LSI PCI-e U320, LSI SAS 9207-8e, LSI SAS 9300-8e,

LSI SAS 9206-16e controllers, and any SAS or SATA internal or external storage.

Thermal Shutdown for the 20xS and 21xS Enclosures

For the 20xS and 21xS enclosures, the operating system shuts down and the server turns off when the

enclosure reaches 0 degrees celsius or 50 degrees celsius. The enclosure turns off after the server is

turned off.

Thermal Shutdown for the 220S and 221S Enclosures

For the 220S and 221S, the operating system shuts down and the server turns off at 0 degrees celsius or

50 degrees celsius if you have not implemented Channel Redundancy and Thermal Shutdown. The

enclosure turns off only when you have implemented channel redundancy enabled smart thermal

shutdown using the command-line interface (CLI) and is set at 0 degrees celsius or 50 degree celsius.

This does not result in data loss because the redundant data resides on the enclosure attached to the

other channel.

The 220S and 221S enclosures automatically turn off when their temperature reaches 55 degrees celsius.

This shutdown occurs even if channel redundancy is implemented or if Storage Management is installed.

You can enable smart thermal shutdown using the command-line interface. For more information, see

the Server Administrator Command Line Interface User’s Guide.
