10 Tach3 In Tachometer for fan3
11 Tach4 In Tachometer for fan4
12 Tach5 In Tachometer for fan5 (outermost fan – close to wall of chassis)
Each fan within the module is capable of supporting multiple speeds. If the internal ambient
temperature of the system exceeds the value programmed into the thermal sensor data record
(SDR), the Baseboard Management Controller (BMC) firmware will increase the rotational
speed for all the fans within fan module.
The fan module is a single component. The individual fans that make up the module are not
swappable or individually replaceable. Should a fan fail, the entire module will need to be
replaced. A tab on the side of the fan module makes replacement of the module tool-less and
very simple. The fan module is not hot swappable. The server must be turned off before the fan
module can be replaced.
