System Description 13
Cooling Subsystem
CAUTIONS
The chassis top cover must be installed and closed for proper system
cooling.
Cooling components must be hot-swapped within a limited time period.
This time period applies only to the time that the cooling component is
removed from the system, not from the time of failure.
The cooling subsystem consists of a hot-swap, redundant (5+1) system fan array installed in the
fan bay. The single bank of six Delta* FFB0612EHE-S18Z hot-swap system fans provide the
airflow necessary to cool the system components. These fans are installed in the fan bay that is
located within the power bay. The fans connect to the fan baseboard. The figure below shows
the location of the fans in the power bay.
