Table 8. Thermal Settings (continued)
Object Description Usage Example
MFSMinimumLimit
Read Minimum limit for MFS
Values from 0 to
MFSMaximumLimit
Default is 255 (means None)
To display the lowest value that
can be set using
MinimumFanSpeed option.
racadm get
system.thermalsettin
gs.MFSMinimumLimit
MinimumFanSpeed
• Allows configuring the
Minimum Fan speed that is
required for the system to
operate.
• It defines the baseline (floor)
value for fan speed and
system allows fans to go
lower than this defined fan
speed value.
• This value is %PWM value
for fan speed.
Values from
MFSMinimumLimit to
MFSMaximumLimit
When get command reports
255, it means user configured
offset is not applied.
To make sure that the system
minimum speed does not
decrease lower than 45% PWM
(45 must be a value between
MFSMinimumLimit to
MFSMaximumLimit):
racadm set
system.thermalsettin
gs.MinimumFanSpeed
45
ThermalProfile
• Allows you to specify the
Thermal Base Algorithm.
• Allows you to set the system
profile as required for
thermal behavior associated
to the profile.
Values:
• 0 — Auto
• 1 — Maximum performance
• 2 — Minimum Power
To view the existing thermal
profile setting:
racadm get
system.thermalsettin
gs.ThermalProfile
To set the thermal profile to
Maximum Performance:
racadm set
system.thermalsettin
gs.ThermalProfile 1
ThirdPartyPCIFanRespon
se
• Thermal overrides for third-
party PCI cards.
• Allows you to disable or
enable the default system
fan response for detected
third-party PCI cards.
• You can confirm the
presence of third-party PCI
card by viewing the
message ID PCI3018 in the
Lifecycle Controller log.
Values:
• 1 — Enabled
• 0 — Disabled
NOTE: The default value
is 1.
To disable any default fan speed
response set for a detected
third-party PCI card:
racadm set
system.thermalsettin
gs.ThirdPartyPCIFanR
esponse 0
Modifying thermal settings using iDRAC settings utility
To modify the thermal settings:
1. In the iDRAC Settings utility, go to Thermal.
The iDRAC Settings Thermal page is displayed.
2. Specify the following:
• Thermal Profile
• Maximum Exhaust Temperature Limit
• Fan Speed Offset
• Minimum Fan Speed
For information about the fields, see the Modifying thermal settings using web interface.
