Enable/Disable Smart Thermal Shutdown
By default, the operating system and server are turned off when the PowerVault 220S and PowerVault 221S enclosures reach a critical temperature of 0 or 50
degrees Celsius. Using the Enable Smart Thermal Shutdown task, however, you can specify that only the enclosure, and not the operating system and
server be turned off when the enclosure reaches a critical temperature.
If the enclosure has virtual disks that are channel-redundant, then the enclosure can be turned off while redundant data continues to be available on another
channel. For more information, see Channel Redundancy and Thermal Shutdown.
To enable or disable thermal shut down:

1. Select the Storage tree view object.

2. Click the Information/Configuration subtab.

3. From the Global Tasks drop-down menu, select Enable Smart Thermal Shutdown or Disable Smart Thermal Shutdown. Depending on the option that
is currently selected, the Available Tasks drop-down menu displays only one of these tasks at a time.
