This reports the administratively configured fan-speed policy setting applying to this fan, per its fanSpeedPolicyAdminState property, for example low, balanced, high-power, or max. This is the setting an admin actually chooses to trade off acoustic noise and power draw against cooling headroom for a chassis, and it's what to check first if a chassis seems louder or runs hotter than expected compared to a similarly configured one. An adminState of 'high-power' versus 'balanced' on two otherwise identical chassis explains why one runs its fans audibly faster than the other.
