Control system
The MCS 5042 includes a control system that constantly monitors the air temperatures, water temperatures, and flow rate. The management module attempts to maintain the air temperature at the target set point. If the set point temperature cannot be maintained, the MCS 5042 management module will generate an alarm and notify facility management systems as configured.
Note:
For site evaluations and technical consulting services for your site, see the
HP mc-Series 5042 User Guide.
Before installing and running active components
Prior to starting up any active components (servers, storage devices, and so on) mounted in the MCS 5042, the following steps must be performed:
1.Ensure that the chilled water source is on and flowing prior to the
2.Ensure that the MCS 5042 is fully operational and running before turning on the servers and closing the front and rear cabinet doors.
Caution:
If the MCS 5042 is left running in manual mode for a period of time without an adequate heat load being generated by servers or other computing and networking devices, excess condensation might occur within the cabinet or system.
For more information on the installation of the MCS 5042, see the MCS 5042 documentation on the HP website (http://h20000.www2.hp.com/bizsupport/TechSupport/DocumentIndex.jsp? contentType=SupportManual&lang=en&cc=us&docIndexId=64179&taskId=101&prodTypeId=34475 89&prodSeriesId=3657806).
