Temperature
Operating 10° to 35°C (50° to 95°F) with a maximum
temperature gradation of 10°C per hour
NOTE: For altitudes above 2950 feet, the maximum
operating temperature is derated 1°F/550 ft.
CAUTION: The maximum number of memory modules
and hard drives supported on 1U and 2U node
configurations, with 130W (4 and 8 core) and 135W
processors, depends on the power supply installed.
