5.2.2.1.5 Fan Control
The chassis fans run in the autonomous mode or the manual control mode and are
configurable via the Set Fan Speed Control command. When the fans are in the
autonomous mode, the fan control speed is determined by the aggregated temperature
level and the selected fan speed profile.Since only one cooling domain (cooling zone) is
supported, one setting is applied to all operating fans. Note that at low temperatures the
system may turn off some or all fans.
5.2.2.1.6 FRU Present State
There are two versions of the Get FRU Present State command. As shown in Table 5-12
Get FRU Present State Version 1 , the command also returns the manufacturer’s IANA
number, Product ID, and the device revision. Such information may not be available if either
the FRU does not provide the information or the FRU is in such a state that it cannot provide
the information to the BMC. In either case, zeros are returned.
