Determine Temperature/Humidity Requirements The following table lists the computer room temperature and humidity specifications for rp7400 servers. Temperature and humidity specificationsa Parameter Recommended Operating Range Recommended Maximum rate of change (per hour) Temperatureb Operating Humidity 41o to 104o F (0o to 40o C) 15% - 80%, non-condensing at 65o C 50o F nonrepetitive 10o C nonrepetitive (repetitive maximums not tested) 30% RH/hour a. These are recommended values. For operation outside these ranges, contact your Hewlett-Packard site preparation specialist. b. At altitudes up to 3,000 meters. NOTE Operating ranges refer to the ambient air temperature and humidity measured at the cabinet cooling air intake vents. 69
