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 8 lists the acceptable temperature and humidity ranges for the EXP395
storage expansion enclosure when in storage or in transit. Table 9 on page 15 lists
temperature and humidity ranges for the storage subsystem in typical Information
Technology (IT) or office environments. Table 10 on page 15 lists temperature and
humidity ranges for the storage expansion enclosure in a NEBS/ETSI compliant
environment.
Note: Substantial deviations from the suggested operating range, in either
