Intel® Server Board S2400SC TPS Platform Management Functional Overview
Revision 2.0 Intel order number G36516-002 65
Note:
1. The above features may or may not be in effective depends on the actual thermal
characters of a specific system.
2. Refer to the Intel server system TPS for the board in Intel chassis thermal and acoustic
management
3. Refer to Fan Control Whitepaper for the board in 3rd party chassis fan speed control
customization.
The server system supports multiple fan control profiles to support acoustic targets and
American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE)
compliance. The BIOS Setup utility can be used to choose between meeting the target acoustic
level or enhanced system performance. This is accomplished through fan profiles. The BMC
supports eight fan profiles, numbered from 0 to 7.

Each group of profiles allows for varying fan control policies based on the altitude. For a given
altitude, the Tcontrol SDRs associated with an acoustics-optimized profile generate less noise
than the equivalent performance-optimized profile by driving lower fan speeds, and the BIOS
reduces thermal management requirements by configuring more aggressive memory throttling.
The BMC only supports enabling a fan profile through the command if that profile is supported
on all fan domains defined for the given system. It is important to configure platform Sensor
Data Records (SDRs) so that all desired fan profiles are supported on each fan domain. If
no single profile is supported across all domains, the BMC, by default, uses profile 0 and does
not allow it to be changed.
