Power & Cooling Fan Failure Detection Function
FRM220-CH02/SMT standalone chassis supports "Power & Cooling Fan Failure Detection"
function. When power warning or failure occurs, users can immediately be notified of the warning or
fault via power LED indicator or "Status" page via NMC card (if this card is inserted).
For fan failure detection, the chassis will use "Auto Sensor" default mode to decide the fan speed if
the NMC card is not used. "Auto Sensor" mode will sense the fan speed depending on the power
current automatically and issue LED warning or alarm notice when the condition meets the threshold
value. When NMC card is inserted, users can select the desired fan speed. Available fan speed
options are FAN 0 (FAN off), FAN1, FAN2, FAN3, FAN4 (Full Speed).
