Specifications and Characteristic Data
Environmental Specification
Operating temperature and humidity ranges may vary depending upon the
mass storage devices installed. High humidity levels can cause improper
operation of disk drives. Low humidity levels can aggravate static electricity
problems and cause excessive wear of the disk surface.
