5.6. Cooling Module Maintenance
5.6.1 Notes on Cooling Module Maintenance
Redundant cooling modules: The system is equipped with four (4)
cooling blowers, two (2) within each cooling module. These cooling
modules control the internal operating temperature and therefore their
working integrity should be maintained at all times.
Detecting a failed cooling module: If a cooling module fails, system
firmware and Galaxy Array Manager manager will deliver warning
events. The LEDs located on the rear of the enclosure will light red and
an audible alarm will be triggered.
Airflow Concern: Once you are notified that a cooling module has
failed, it should be replaced as soon as possible. A failed module should
only be removed from the system when you have a replacement module
immediately available.
