Management module

Management module overview

The HPE Adaptive Rack Cooling System has a management module, which can be accessed remotely
through the web interface. The management module analyzes, queries, and manages various
measurements and warning and alarm messages from the unit.
The management module analyzes measurements provided by each sensor or module, generates any
necessary warning or alarm messages, and then sends them to the web interface. When a new warning
or alarm occurs, the warning and alarm messages appear on the operator display as well as on the web
interface Alarms menu and Alarm History menu. If an alarm relay is installed on the HPE Adaptive Rack
Cooling System and enabled in the appropriate web interface menu, it is also activated and an audible
alarm is signaled by the internal beeper.
The management module performs regulation operations such as:
• Retrieving all sensor measurements at a rate of approximately once per second.
• Analyzing all measurements and generated alarm and warning messages
• Controlling fan speeds and water valve positions
• Sending various system values to the web interface
The web interface displays various measurements and warning and alarm messages from the
management module. Also, various system values can be set through the web interface and sent to the
management module. For more information about the web interface, see the HPE Adaptive Rack Cooling
System Web Interface User Guide.
