Because these temperatures might be significantly higher than the temperatures of the other equipment in the data center, it may be necessary to adjust the set-points of the CRACs or CRAHs upwards so as not to over-cool the air. Most standalone CRACs and CRAHs use return side temperature regulation rather than supply side. Since the supply side air temperature is the parameter of interest to meet the 15-32° C limits for the proper operation of Superdome2, the return air set-point may need to be increased upwards to maximize the capacity of the CRACs or CRAHs. IMPORTANT: Care must be taken when adjusting the set-point of any CRAC or CRAH such that the actual inlet temperature specified for any equipment is not exceeded. For more information about general site preparation guidelines, see the Generic Site Preparation Guide. Air quality specifications Chemical contaminant levels in customer environments for HP hardware products must not exceed G1 (mild) levels of Group A chemicals at any time, as described in the current version of ISA-71.04 Environmental Conditions for Process Measurement and Control Systems: Airborne Contaminants. See http://www.isa.org/ for more information. For more information about general site preparation guidelines, see the Generic Site Preparation Guide.
