Technical Guide

Environmental specifications
The table below details the environmental specifications for the platform. For additional information about environmental
measurements for specific system configurations, see https://www.dell.com/learn/us/en/uscorp1/product-info-datasheets-
safety-emc-environmental .
An important feature of having a broad menu of different categories is to allow the same platform model to have different
operational ranges depending on the MRD defined.
A list of range categories for different configurations shall be identified by thermal team as early in the project as possible.

Table 29. Operational Climatic Range Categories
Category A2 Allowable Operation
Temperature Ranges (For Altitude <900 meters or 2953 feet) 10 to 35°C (50 to 95°F) with no direct sunlight on the
platform
Humidity Percent Ranges (Non-Condensing at all times) 8%RH with -12°C minimum dew point to 80%RH with 21°C
(69.8°F) maximum dew point
Operational Altitude De-Rating Maximum temperature is reduced by 1°C/300 meters
(1.8°F/984 feet) above 900 meters (2,953 feet)
