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 13 lists the acceptable temperature and humidity ranges for the EXP810
storage expansion enclosure when in storage or in transit. Table 14 lists
temperature and humidity ranges for the storage expansion enclosure in typical
Information Technology (IT) or office environments. Table 21 on page 26 lists
temperature and humidity ranges for the storage expansion enclosure in a
Telco/NEBS-3 compliant environment.
Note: Substantial deviations from the suggested operating range, in either
