4.14.6 Hot Swap Fan Support
Some chassis and server boards provide support for hot-swap fans. These fans can be
removed and replaced while the system is operating normally. The BMC implements fan
presence sensors for each hot swappable fan. When a fan is replaced, the fan speed for the
domain is temporarily set to high (kick-start) to ensure proper fan starting.
Note: See the server or workstation Technical Product Specification that applies to your product
for more detailed information
4.15 Acoustic Management
Acoustic management refers to enhanced fan management to keep the system optimally cooled
while not creating unnecessary noise.
4.15.1 Fan Profiles
The system can be configured through a BIOS setup screen option to give preference to meet
the target acoustic level for the system at the expense of system performance, or to provide
enhanced system performance at the expense of louder fans. This is accomplished with fan
profiles. At the system boot, the BIOS will query the BMC to determine what fan profiles are
supported. The BIOS indicates the chosen setup screen option to the BMC.
4.15.2 Interactions with DIMM Thermal Management
4.15.2.1 Thermal Profile Data
The BIOS requires knowledge of various characteristics to use as input into its calculations for
DIMM throttling setup. This is dependent on which fan profile is enabled. The BIOS retrieves
this platform-specific information from the BMC at system boot.
The BMC supports this with Thermal Profile Data SDRs, which allow this data to be stored in
the BMC’s SDR repository and can be customized per platform and per fan domain. On
systems that support multiple profiles, each Thermal Profile SDR can apply to one or more
profiles in a given fan domain.
4.16 PSMI Support
Platforms that use the Intel
®
5000 Series Chipsets support PSMI v1.44 compliant power
supplies. Some power supplies may not support certain optional features, such as current
monitoring.
