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.
