As BMC needs to poll HSCBP sensor continuously, new sensor 0xF0 has been added and the same is clamped forDomain 4 which is same as HSC BP temp sensor 0x01.As the power supplies and the hard disks must always have sufficient cooling, the finalpower supply fan speed RPM must be the maximum fan speed required by items 1, 2 3and 4 above.3.28.4 Power Supply Failure ManagementSince the system supports several power supply configurations, this section will describe thesystem level fan speed control reaction to some specific failure modes.System Configuration refers to the initial non-failure or non-hot swap configuration. Thefollowing table is limited to rotor failures for the power supply fans only. This is not based on anysystem fan failures.Table 17.
