PSU/Cooling Module
The PS 2000 Series system has two redundant hot-swappable PSU/cooling modules that
provide power and help with the airflow, providing an efficient ventilation.

When the cooling modules operate under normal conditions, the cooling fans run at a low
speed. The cooling fans raise their rotation speed to increase the airflow under the following
conditions:
•
Component failure: If the cooling module, PSU, or temperature failed.
•
Elevated temperature: If the temperature breaches the upper threshold set for any of the
interior temperature sensors.
During the initialization stage, the cooling fans operate at a high speed. The speed is lowered
when the initialization is complete and no errors are detected.
NOTES:
•
The PSU/Cooling Modules have specific installation orientations for left and right slots.
Refer to the label on the back of the system.
•
There are two upper temperature thresholds: one for event notification and the other for
triggering high fan rotation speed. You can change the preset values for event notification
using the firmware – embedded configuration utility. Refer to the firmware operation
manual for details.
