Environmental requirements and specifications
This section describes the environmental requirements and specifications for the
DS5020 storage subsystem, including temperature and humidity, altitude, airflow
and heat dissipation, shock and vibration requirements, and acoustic noise levels.

Temperature and humidity

Table5 on page 21 lists the acceptable temperature and humidity ranges for the
DS5020 storage subsystem when in storage or in transit. Table6 on page 21 lists
temperature and humidity ranges for the storage subsystem in typical Information
Technology(IT) or office environments.
Note: Substantial deviations from the suggested operating range, in either
direction, if sustained for extended periods of time, will expose the unit to
greater risk of failure from external causes.
Important: The operating environment air temperature must be 22° C (72° F) or
lower.
