Environmental requirements and specifications
This section describes the environmental requirements and specifications for the storage expansion
enclosure, including temperature and humidity, altitude, airflow and heat dissipation, shock and
vibration requirements, and acoustic noise levels.
Temperature and humidity
Table 7 lists the acceptable temperature and humidity ranges for the DCS3700 storage expansion
enclosure when in storage or in transit.
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.
