You must set the server altitude so that the server can adjust its fan speeds and monitor the surrounding environmental conditions required for its elevation.
Set the server altitude using the SP system_altitude property.
Setting the system_altitude property causes the server to adjust the temperature thresholds so it can more accurately detect any abnormality in the air intake temperature. However, even if you do not set the system altitude, the server still detects and responds to any abnormality in the air temperature, such as the temperature of the processors.
ok #. ->
-> set /SP system_altitude=altitude
Replace altitude with the altitude of the data center in meters. The possible values are 0 to 3000 meters. The default value is 200m.
