Chapter 2 Cabinet and Environmental Specifications 17
Environmental Requirements
This section describes the environmental conditions that are prerequisite to installing
a cabinet.
Temperature, Humidity, and Altitude
TABLE 2-2
lists operating and nonoperating temperature, relative humidity, and
altitude ranges for a typical cabinet.
Table 2-4 lists the acceptable temperature and humidity ranges in which the Sun
StorageTek 6540 array is designed to operate. Better reliability is obtained when
equipment is operated at nominal temperatures (air-conditioned environments).
