Power and Thermal Resource Tree

The API section name has been changed to "Power and Thermal resource tree." The subsections are "PowerSubsystem," "ThermalSubsystem," etc.

Description: We will follow DMTF spec (2020.4) to deprecate the Thermal and Power schema starting with Gen 14. Reference link: https://redfish.dmtf.org/schemas/Redfish_Release_History.pdf.

PATCH FansFullSpeedOverrideEnable

Note: The FansFullSpeedOverrideEnable property is supported since BMC firmware versions Gen 13 1.12 and Gen 14 1.10.

URI: /redfish/v1/Chassis/1/ThermalSubsystem

Method: PATCH

Value: true, false

Payload:

{

"FansFullSpeedOverrideEnable": false

}

Response: 200

Notes: 

  • Set FansFullSpeedOverrideEnable to false.

  • Fan mode will be the mode of/redfish/v1/Managers/1/Oem/Supermicro/FanMode.

  • If the user modifies other fan modes via IPMI or oem redfish (such as PUE) with FansFullSpeedOverrideEnable as true, then the mode of /redfish/v1/Managers/1/Oem/Supermicro/FanMode will be PUE.

  • Whether FansFullSpeedOverrideEnable is true or false, this does not change the mode of /redfish/v1/Managers/1/Oem/Supermicro/FanMode.
